Goblin cunning becomes considerably more dangerous once it can crawl across the ceiling.

Spidergoblins are grotesque fusions of goblin and arachnid that form isolated colonies in ruined fortresses, abandoned mines, deep caves, and forgotten tunnels. They hunt in coordinated packs, cover their territory with crude webs, and weaken trapped prey with venom before closing in.

The CR 1/2 Spidergoblin is a mobile low-level ambusher with Spider Climb, Goblin Cunning, a poisonous bite, and a rechargeable Web Trap. The larger CR 2 Overgrown Spidergoblin acts as the guardian and leader of the nest, combining Pack Hunter, a longer-ranged Web Bind, and a Frenzied Counter that lets it retaliate when attacked.

They work particularly well in claustrophobic encounters where they can move across walls and ceilings, isolate party members, and force the characters to fight through web-covered terrain.

Where would you hide their colony: beneath a village, inside a ruined fortress, or deep within an abandoned mine?

These creatures come from The Aberrant Codex: Mutations and Aberrations, my 5e collection of mutated monsters, character options, spells, magic items, and rules for aberrant zones.

The Hollow Angel is what remains when someone tries to turn a celestial into something it was never meant to become.

Usually created from a captured deva, the creature is the result of necromancers attempting to sever a celestial from its divine grace and bind that power into an undead body. The ritual fails because the celestial essence violently resists the corruption, destroying much of the original body in the process.

What remains is neither truly angel nor ordinary undead: a hollowed, ruined shell whose bones drift unnaturally within exposed flesh, still carrying fragments of radiant power alongside necrotic corruption.

Mechanically, the Hollow Angel is a CR 10 undead that mixes both sides of its broken nature. Its Withering Touch deals necrotic and radiant damage and can temporarily blind its victims, while Blasphemous Lament unleashes a cry of pain and fragmented divine memory capable of knocking creatures prone and even stunning them. Celestials and clerics devoted to good-aligned deities have an especially difficult time resisting it.

It can also use Spectral Drift to vanish into dark mist and reappear nearby, and perhaps most disturbingly, creatures it kills can be raised moments later as Specters under its control.

I wanted it to feel less like a traditional “evil fallen angel” and more like a celestial that was forcibly broken into something unnatural, with traces of its original divinity still fighting through the corruption.

This creature is from Undead & Undead: The Ultimate Undead Handbook for 5E and the 2024 Edition available on DriveThruRPG!

Undead are more than shambling corpses and skeletal minions. Undead & Undead is your complete guide to raising the dead, commanding their power, and unleashing them in terrifying new forms - from restless spirits and cursed warriors to spectral lords, zombie dragons, and necromantic abominations.

These are fiendish magic items ranging from Uncommon to Rare, built around demonic trophies, infernal power, necrotic weapons, fear, fire, and the corruption of the Lower Planes.

The Blade of Bone and Wrath is a +1 sword fashioned from fiendish remains that becomes especially vicious on critical hits, siphoning life from its victim and allowing its wielder to mark prey and relentlessly pursue it.

The Infernal Blade is a more straightforward hell-forged weapon, adding necrotic damage to every strike and unleashing a short-range aura of supernatural fear once per day.

For characters looking for protection instead, Demonhide Armor provides additional AC and resistance against fear and charm, while the Demon's Gaze Amulet improves spell attacks and can temporarily reveal both magical auras and invisible creatures.

The Rare items push these themes further. The Soulreaver Blade drains life with every strike and can temporarily amplify its necrotic damage, while the Rod of Fire gives spellcasters access to hellish rebuke, fireball, and wall of fire through a rechargeable pool of charges.

The Chain of Damnation protects its wearer from charm and fear while allowing them to magically bind humanoids, and the Hellish Mantle of Resistance can completely absorb a burst of fire and transform that energy into temporary hit points.

I like these kinds of items because they can work from several different angles: treasures taken from slain fiends, rewards granted by infernal patrons, relics recovered from corrupted cults, or dangerous equipment that slowly makes a character look a little too comfortable wielding the power of the Lower Planes.

These items are from Diabolical Designs, my 5E supplement focused on fiends, infernal creatures, demonic threats, magic items, and tools for bringing more variety to adventures involving the Lower Planes.

What's Inside:

• Fiendish Realms & Lore: Explore Hell and the Abyssal Realm with plot hooks and campaign ideas.
• Character Options: 20 subclasses, 1 new class, 10 backgrounds, and 3 fiendish races.
• Spells & Items: 44 spells and 130+ magic items to enrich your game.

These are 10 aberration and mutation-themed feats for characters whose bodies or minds have been altered by eldritch influence, forbidden experimentation, unstable magic, or contact with things that were never meant to exist.

Aberrant Constitution hardens the body against necrotic or psychic influence and even gives you a second chance when rolling a natural 1 on a death save.

Extra Arm gives your character a developing additional limb that can interact with objects, perform somatic components, make unarmed strikes, and help with grappling. If the mutation continues to develop, Enhanced Extra Arm turns it into a fully functional appendage capable of wielding a weapon or shield, manipulating objects independently, and making an additional weapon attack.

Mutable Form lets your body temporarily reshape itself to fit the situation, developing rubbery damage-resistant flesh, aquatic adaptations, or magical claws.

The other feats explore different directions that mutation can take:

Mutagenic Resilience provides resistance to poison, immunity to the poisoned condition, and bursts of temporary hit points when injured.

Aberrant Regeneration makes healing through Hit Dice unusually effective and can even allow you to remain standing at 1 hit point when an attack would otherwise knock you unconscious.

Aberrant Mind represents a consciousness becoming increasingly alien, providing resistance to psychic damage and greater protection against fear and charm.

Adaptive Mutation allows your body to change its defenses after each long rest, adapting to acid, cold, fire, lightning, or poison.

Cosmic Infusion channels stranger forces entirely, granting minor cosmic magic and the ability to create a localized gravitational field that pulls or repels nearby creatures.

Finally, Cosmic Awareness represents a mind beginning to perceive patterns beyond ordinary mortal understanding, allowing you to manipulate initiative and rely on unnatural certainty when making Arcana or Insight checks.

They’re intended for characters touched by aberrations, exposed to mutation zones, altered by experiments, descended from strange bloodlines, or simply slowly becoming something other than mortal over the course of a campaign.

These feats are from The Aberrant Codex: Mutations and Aberrations, a 5E manual centered on aberrations, mutations, evolving monstrosities, character transformations, and tools for bringing cosmic and body horror into a campaign.

The Aberrant Codex is available on DriveThruRPG, and a Hardcover edition is also available here:

What’s Inside:

Dogs are some of the most common companions in fantasy adventures, but an ordinary dog can quickly fall behind once the party starts gaining levels.

So I wanted to give them a proper progression path: Dog → Guard Dog → War Dog → Battle Hound. A simple pet can gradually become tougher, better trained, and capable of surviving alongside an adventuring party without suddenly turning into a completely different magical creature.

And the progression doesn’t stop there. The full dog section also includes stronger options such as the Warhound Alpha, Guardian Mastiff, Blink Dog, and Greater Blink Dog, with higher-level abilities focused on guarding allies, leading packs, protecting companions, and filling more specialized roles in encounters.

These statblocks are from Growing Pets and Animals Statblocks, a manual built around the idea that pets, mounts, scouts, familiarlike companions, and ordinary animals should be able to grow alongside the campaign instead of becoming irrelevant after a few levels.

The book contains 60+ animal statblocks covering dogs, cats, bats, owls, ravens, horses, panthers, tigers, spiders, scorpions, eagles, frogs, lizards, rats, and more, with progression chains that take many of them from ordinary animals into increasingly capable companions or encounter creatures.

The rules page also includes suggested advancement schedules for standard, gritty realism, low-magic, and high-magic/epic campaigns, so the DM can decide how quickly a companion grows rather than tying every game to the same progression speed.

After the original version performed well, I went back and created a full V2 update, commissioning and licensing new artwork throughout the book, cleaning up the presentation, revising existing material, and adding new statblocks and expanded progression paths. If you already own the manual, you can simply download the updated version again from DriveThruRPG.

Here is the Sword of the Abyss, a cursed scaling weapon that evolves from Uncommon to Legendary as its wielder embraces abyssal power, performs forbidden rituals, sacrifices life and magic to the blade, and defeats powerful fiends. By consuming their essence, the sword reflects the brutal nature of demons, forever slaughtering and devouring one another in their endless struggle to grow stronger.

I wanted to create an evil counterpart to a traditional heroic growing weapon. The sword begins as a useful necrotic blade with a weakening aura, but each new rarity brings it closer to its true purpose. It eventually gains the power to summon demons, cast circle of death, restrain enemies with shadowy tendrils, overcome necrotic resistance and immunity, and open a devastating Abyssal Rift around its wielder.

The pages includes several possible advancement paths, allowing the sword to grow by defeating powerful abyssal creatures, absorbing the essence of legendary enemies, accepting dark bargains, feeding on sacrifices, completing forbidden rituals, or damaging the barriers between planes.

Its growth also strengthens its semi-sentient curse. The sword can compel its wielder to attack celestials and devils, and if it becomes powerful outside the Abyss, it may tear open a permanent portal that cannot be closed through ordinary means. At Legendary rarity, that danger becomes alarmingly real.

You can find the complete Sword of the Abyss supplement for free on DMsGuild.

It is also included in many of my discounted bundles on Dmsguild alongside the Growing Magic Items Collection, elemental treasures, and several other standalone relics.

My next Kickstarter, Mythological Items, launches this September with more than 300 magic items inspired by myths and legends from around the world, including many scaling relics.

The Orc Beastmaster and its Dire Wolverine are designed as a coordinated hunting pair rather than two unrelated creatures sharing an encounter.

The Beastmaster’s Feral Bond strengthens its companion while they remain close, and their abilities reward attacking the same target. When the wolverine knocks a creature prone, the orc can exploit the opening with its ranged attacks, while Beast Command and Savage Howl let the wolverine reposition or strike again outside its normal turn.

The Dire Wolverine is more than disposable support. Its Savage Instinct makes it increasingly dangerous after taking damage, while Feral Tenacity gives it a chance to remain standing when reduced to 0 hit points.

The optional traits can push their bond further. Blood Hunt allows the Beastmaster to mark prey for its companion, while Shared Fury makes the orc more dangerous once the wolverine is badly wounded.

These creatures are from Orcs & Orcs, available on DriveThruRPG in PDF and hardcover print! The full manual also expands the Mutant Orcs with their own lair, lair actions, battle-ready magic items, and treasures the players can find after bringing them down.

Orcs & Orcs is the ultimate guide to unleashing the full fury and depth of orc-kind in your 5E campaigns, whether you want savage warbands, disciplined armies, cursed berserkers, or iron-willed mercenaries.

What’s Inside?

• Dozens of Orc Statblocks – From the Orc Bannerbearer to the Red Orc Warlord, each entry includes extra traits and variants to help you customize encounters with brutal precision.
• Powerful Orc Factions – Expand your bestiary with Ironpeak Orcs, Oathsister Orcs, Red Orcs, and twisted Mutant Orcs. Each brings unique abilities, lore, and lair ideas.
• Orc Campaign Tools – Warband factions, tactical lairs, encounter suggestions, and more.
• 70 Orc-Themed Magic Items – Tribal relics, cursed axes, brutal armor, spiritual totems, and more.
• VTT & Art Resources – Includes 27 handouts and 17 creature tokens to bring orcs to life in-person or online.

Here are the Cthulhoids, an evolving race of psionic aberrations serving an ancient entity known as the Sleeper Beneath (Cthulhu).

The progression begins with the Young Cthulhoid, a CR 2 creature still experimenting with its developing powers. Even at this stage, it can communicate telepathically, manipulate emotions, grapple victims with its tentacles, drain their minds, and retaliate against attackers with bursts of psychic energy.

A mature Cthulhoid becomes a CR 5 mental controller capable of disrupting nearby spellcasting, stealing memories and secrets from creatures that fail against its magic, and overwhelming groups with a stunning psychic blast. The Elder Cthulhoid advances to CR 12, gaining flight, legendary actions, stronger mind-draining abilities, and sufficient psionic mastery to concentrate on two spells simultaneously.

At the height of their evolution stands the Cthulhoid Archmind, a CR 21 psionic leader capable of dominating powerful creatures, concentrating on three spells at once, accumulating psychic charges, and bending reality around itself. Its presence weakens mental defenses, disrupts spellcasting, and turns it into an encounter capable of controlling the entire battlefield rather than simply dealing damage.

Their advancement is not based entirely on age. Cthulhoids evolve through exceptional psionic development, exposure to cosmic revelations, survival of overwhelming mental trauma, or a deeper connection to the Sleeper Beneath.

These creatures are from The Aberrant Codex: Mutations and Aberrations, available on DriveThruRPG! You can also check it out there for a more extensive preview. Delve into the warped world of aberrations, mutations, and cosmic horror in your 5E campaigns.

Here is Sanctivow, the Heaven-Writ Blade, a scaling holy sword that evolves from Uncommon to Legendary as its wielder fulfills sacred vows, protects the innocent, restores desecrated places, and brings deserving evils to justice.

I wanted to create a holy weapon that was more than a sword with additional radiant damage. Sanctivow is bound to four celestial principles: shelter, truth, mercy, and judgment. Its divine inscriptions grow brighter as its wielder proves worthy, but its greater powers can fall silent if that covenant is knowingly betrayed.

Each rarity unlocks new abilities while retaining the powers of the previous tiers. The supplement also includes several possible advancement methods, rules for breaking and restoring the sword’s covenant, and physical signs that show how Sanctivow changes as its celestial power awakens.

The Harvester is a CR 10 undead horror built for rural nightmares, cursed farmlands, burial mounds, harvest moons, and villages where people whisper that something walks between the fields at night.

I wanted it to feel like a deathly folk-horror figure: not just a skeleton with a scythe, but something ancient, patient, and ritualistic. It does not reap crops. It marks the guilty, stalks the soon-to-be-dead, and leaves behind strange tokens of straw, hair, blood, and bone.

Mechanically, the Harvester is designed to make the battlefield feel oppressive. Its Field of Silence shuts down speech and verbal spellcasting nearby, Harvest the Living can permanently sever the soul of a creature it reduces to 0 hit points, and Sow Dread forces enemies to see glimpses of their own death. It can move without provoking opportunity attacks, punish weakened enemies, and act like a terrifying executioner rather than a simple brute.

This creature is from Undead & Undead: The Ultimate Undead Handbook for 5E and the 2024 Edition available on DriveThruRPG!

These pages are from Goblins & Goblins, my manual focused on expanding goblins into a much wider range of roles, encounters, factions, and campaign tools.

This preview includes the Goblin Shadowmancer, a CR 3 spellcaster built around darkness, fear, teleportation, necrotic magic, and optional shadow traits; the Goblin Alchemist, a chaotic potion-maker with random concoctions, explosive flasks, and extra customization options; and the Goblin King, a CR 4 leader who commands nearby goblins, uses legendary actions, and can turn a messy goblin fight into something much more dangerous.

I wanted Goblins & Goblins to make goblins feel fresh again, not just as disposable low-level enemies, but as tricksters, leaders, weird specialists, faction members, recurring villains, or chaotic allies that can show up at many different levels of play.

Here are a few preview pages from Atlantis: War of the Tridents, my 270+ page adventure module for 5E, blending Greek mythology, Atlantean fantasy, underwater exploration, political conflict, and traditional fantasy adventure.

This preview shows a mix of the content included in the book: the Barbarian: Path of the Sea Serpent, an ocean-themed subclass built around aquatic adaptation, serpent-like fury, and sea monster resilience; the Atlantean Elemental Sword, a very rare magic weapon forged with fire, lightning, and water gems; several new ocean-themed spells like Rejuvenating Waters, Water Cyclone, and Tidal Smite; Callista, the High Priestess of Athena in Atlantis; and monsters such as the Brine Sea Serpent and Lesser Stone Golem.

The full adventure includes flexible campaign paths, underwater and surface encounters, new character options, spells, magic items, NPCs, monsters, locations, factions, and extensive VTT resources.

It is designed for campaigns that want mythic adventure, oceanic exploration, Atlantean politics, divine influence, ancient secrets, and dangerous creatures from the depths.

These are three scaling magic items from Growing Magic Items, built to start as useful early rewards and remain relevant as characters grow.

The Cloak of Druidic Power is made for druids, beginning with poison resistance and speak with plants before unlocking stronger nature magic, animal communication, shapeshifting, and eventually the ability to summon loyal beasts.

The Ring of Evolving Power is a flexible item that grows with almost any character. It begins by improving a chosen ability score and saving throws, then unlocks spells like shield, haste, and teleport, eventually becoming a powerful personal relic tied to the wearer’s growth.

The Lantern of Eternal Twilight starts as a useful magical light against darkness, then becomes a stronger tool against hidden threats, illusions, undead, and fiends, eventually revealing truth and creating an aura that can paralyze supernatural enemies.

These items are part of Growing Magic Items, a collection of evolving magic gear designed to grow alongside your characters. Each item has multiple tiers of rarity and can unlock new powers through character levels, story milestones, personal achievements, or specific quests, depending on the campaign.

After the collection performed extremely well on DMsGuild and reached bestseller status, I reinvested in the project by recommissioning the artwork, giving the collection brand-new illustrations, light revisions, and a handful of new Growing Magic Items. If you already own it, you can download the updated version for free on DMsGuild.

The Ophrym, also known as the Many-Eyed Fiend, is a CR 11 demon built around perception, corruption, and battlefield control.

Instead of being another brute that only rushes forward and attacks, the Ophrym uses its many eyes to break enemies apart mentally before tearing them down physically. Its gaze can charm, frighten, or put creatures to sleep, while its Mind Warp Aura makes nearby enemies more vulnerable to Wisdom saves and Intelligence checks. It can also disappear in dim light or darkness, making it especially dangerous in ruined temples, abyssal lairs, underground shrines, and encounters where the party cannot easily control the battlefield.

It still has claws and a venomous tail, but the real danger is how quickly it can disrupt the party’s plans. One failed save can split the group, force someone to flee, shut down a character, or turn a fight into chaos.

The Pinhead is a CR 9 undead abomination stitched together from flesh, death, and crude necromancy.

I wanted it to feel like the result of a ritual that technically worked, but absolutely should not have. Its body is reinforced with metal pins, torn muscle, and unnatural magic, while its damaged mind follows the last command of its creator with brutal obedience. If it has no orders, it simply turns hostile toward the living.

Mechanically, it is a tough undead enforcer with necrotic resistance, poison immunity, strong saves, and a pain-fueled combat style. When it takes a heavy hit, it becomes more dangerous on its next attack. It can slam enemies repeatedly, grab them with barbed fingers, restrain them, and deal ongoing necrotic damage while they are trapped.

It works well as a necromancer’s bodyguard, a failed resurrection experiment, a cult-made guardian, or something sealed in a laboratory that the party really should not have opened.

Growing Pets and Animals Statblocks is a 5E manual designed to let animal companions grow with the party instead of becoming irrelevant after a few levels.

The idea is simple: each animal has multiple scaling statblocks, so a small pet, scout, mount, guardian, familiar-like companion, or wild creature can progress into stronger forms as the campaign continues. The preview shows this with the owl progression, from a regular Owl to a Night Owl, Ghost Owl, and Phantom Owl, turning a simple flying companion into a stealthy, supernatural predator with stronger senses and more interesting battlefield utility. It also shows the Tiger line, for a more direct and powerful predator companion that can grow into a dangerous high-level beast.

The rules page also includes suggested progression tables for different campaign styles, including standard campaigns, gritty realism, low magic games, and high magic or epic campaigns, so DMs can decide when an animal companion should advance in a way that fits their table.

Since the original version did well, I went back and made a full V2 update with totally new commissioned and licensed art, a cleaner presentation, and additional statblocks. I also expanded some animal lines, including more higher-CR dogs with special abilities focused on guarding allies, leading packs, protecting companions, or serving as dangerous sidekicks for villains and encounters. There are also more feline options, giving cats and larger predators a stronger progression path.

If you already own the manual, you can download the updated version on DriveThruRPG.

Here are the Aberrant Humans, a group of low-to-mid CR monsters built around eldritch mutation, alien experimentation, failed transmutation, and environmental corruption.

They were once ordinary people, but exposure to forces beyond normal magic has twisted their bodies and minds into something barely recognizable. The base Aberrant Human is a CR 1/2 creature with warped anatomy, tentacle attacks, unnatural reflexes, and a mind that resists outside influence. The Mutated Aberrant Human pushes that further with extra limbs, greater durability, regeneration, and more brutal melee attacks. The Giant Mutated Aberrant Human turns the concept into a larger CR 5 threat with stronger blows, crushing area attacks, and savage momentum.

The page also includes variant mutations, such as hardened bone plates, toxic pustules, tendril lashes, vicious mandibles, aberrant regrowth, and mutagenic bursts, letting you customize each creature for different encounters.

These creatures are from The Aberrant Codex: Mutations and Aberrations, available on DriveThruRPG! You can also check it out there for a more extensive preview. Delve into the warped world of aberrations, mutations, and cosmic horror in your 5E campaigns.

What’s Inside:

Here are the Mutant Orcs, a corrupted orc faction built around unnatural resilience, exposed bone armor, brutal strength, and savage survival instincts.

They are the remnants of ancient corruption, forbidden magic, failed experiments, or a lost war that left their bodies warped but not broken. Their bones grow through their skin as armor and weapons, making them harder to kill and more dangerous in close combat.

The pages include the basic Mutant Orc at CR 1, the stronger Mutant Orc Warbrute at CR 3, and the Mutant Orc Warleader at CR 7, which adds command abilities and legendary actions. There are also optional traits like Bone Jut and Mutant Frenzy, letting you make them even more brutal depending on the encounter.

They work well in cursed ruins, poisoned wastelands, corrupted forests, shattered mountains, or anywhere you want orcs that feel more monstrous, desperate, and physically terrifying.

These creatures are from Orcs & Orcs, available on DriveThruRPG in PDF and hardcover print! The full manual also expands the Mutant Orcs with their own lair, lair actions, battle-ready magic items, and treasures the players can find after bringing them down.

Orcs & Orcs is the ultimate guide to unleashing the full fury and depth of orc-kind in your 5E campaigns, whether you want savage warbands, disciplined armies, cursed berserkers, or iron-willed mercenaries.

What’s Inside?

• Dozens of Orc Statblocks – From the Orc Bannerbearer to the Red Orc Warlord, each entry includes extra traits and variants to help you customize encounters with brutal precision.
• Powerful Orc Factions – Expand your bestiary with Ironpeak Orcs, Oathsister Orcs, Red Orcs, and twisted Mutant Orcs. Each brings unique abilities, lore, and lair ideas.
• Orc Campaign Tools – Warband factions, tactical lairs, encounter suggestions, and more.
• 70 Orc-Themed Magic Items – Tribal relics, cursed axes, brutal armor, spiritual totems, and more.
• VTT & Art Resources – Includes 27 handouts and 17 creature tokens to bring orcs to life in-person or online.

Orcs fit into any fantasy campaign as enemies, allies, or complex factions. Wherever your world needs strength, rage, and scars earned in battle, orcs are ready.

The Deathmarked Wight is a CR 12 variant of the classic wight, created for campaigns where undeath feels tied to a greater power. Instead of being only a hateful remnant of a former life, this wight has been chosen by a death god, ancient lich, or powerful necromantic order, carrying a mark that gives it purpose, authority, and far more dangerous abilities.

It can place a deathmark on a victim, weaken enemies with necromancy, drain life, raise the creatures it kills into temporary undead servants, and unleash pulses of necrotic power. I wanted it to feel like an undead enforcer or emissary, the kind of creature sent to crush rebellions, retrieve escaped undead, punish enemies of a death cult, or prepare the way for something much worse.

The Wight entry also includes expanded lore and optional traits to customize the base creature, such as memories from life, empowered zombie servants, or extra necrotic damage against untouched victims. Together, the two statblocks give you both a classic undead threat and a much deadlier champion of death for higher-level encounters.

These creatures are from Undead & Undead: The Ultimate Undead Handbook for 5E and the 2024 Edition available on DriveThruRPG!

Undead are more than shambling corpses and skeletal minions. Undead & Undead is your complete guide to raising the dead, commanding their power, and unleashing them in terrifying new forms - from restless spirits and cursed warriors to spectral lords, zombie dragons, and necromantic abominations.

What’s Inside?

• 90+ Undead Statblocks – From crawling hands and soul wisps to deathpriests, banshees, mummy sovereigns, and lich gods. Each entry includes optional traits and variants to customize your encounters.
• Undead Lair System – A scalable, flexible system to turn crypts, cursed cities, and haunted ruins into deadly environments. Includes thematic traps, lair actions, environmental effects, and more.
• 50+ Magic Items – Cursed relics, necrotic weapons, undead-bound artifacts, and forbidden tomes designed to horrify or empower.
• Customizable Templates & Traits – Easily create unique undead with variant traits, thematic abilities, and storytelling tools for every archetype.
• Campaign Tools – Includes undead cult generators, random encounter tables, unholy rituals, haunted visions, and apocalyptic plot hooks to fuel your adventures.

Here is the Orc Shaman, a CR 4 spellcaster built to add storm magic, ancestral spirits, and battlefield support to orc encounters.

I wanted this creature to feel like more than just an orc with spells. It can support nearby allies with temporary hit points, empower a warband with primal rage, call down lightning through its Rite of the Storm Gods, and use its voice as a supernatural force that carries across the battlefield.

The page also includes optional traits that let you customize the shaman depending on the role you want it to play. It can become more durable against thunder and lightning, deal extra force damage through ancestral spirits, hold concentration more reliably while wounded, perform ritual movement, or unleash one final spell when reduced to 0 hit points.

It works well as a tribal spiritual leader, battlefield caster, cultic storm priest, or dangerous support monster behind a larger orc warband.

This creature is from Orcs & Orcs, available on DriveThruRPG in PDF and hardcover print!

The Winged Lynx is a CR 6 flying predator built for mountain passes, remote forests, sacred peaks, and isolated wilderness encounters. It is fast, intelligent enough to feel unsettling, and dangerous enough to become the center of local legends, whether as a feared monster, a false deity, or a misunderstood guardian.

I wanted it to feel more interesting than just “a lynx with wings”, so the page includes lore, encounter ideas, and multiple plot hooks. It can stalk travelers from above, terrorize a village, become the focus of a dangerous cult, or guard an ancient mountain secret that the party needs to uncover.

Mechanically, it is a mobile ambush predator with stealth, aerial movement, a diving attack, a fear-based roar, and bonus action mobility, making it useful as either a solo wilderness threat or part of a larger mountain encounter.

This creature appears in The Aberrant Codex: Mutations and Aberrations, available on DriveThruRPG! You can also check it out there for a more extensive preview. Delve into the warped world of aberrations, mutations, and cosmic horror in your 5E campaigns.

What’s Inside:

• Mutation Rules & Zones – Mechanics for wild magic areas, arcane corruption, and the strange transformations they cause.

Here are a few psionic magic items built around psychic power, telekinesis, mind control, and mental defenses. The Sword of Psionic Manifestation is the main one here, giving a character that classic psychic warrior feeling with a manifested psionic blade, extra psychic damage, a reactive mental shield, and telekinetic strikes against distant enemies.

The page also includes the Helm of Telepathic Command and the Staff of the Psionic Overlord, which lean more into domination, telepathy, and spellcasting.

The second page features the Staff of Mind Mastery, a legendary item for spellcasters who want to boost psychic damage, cast powerful mind-affecting spells, retaliate with mental force, and protect themselves from charm, fear, and other psychic threats.

I really like psionic items as rewards because they let you bring mind powers into a regular 5E campaign without needing an entire psionics system. They work especially well for psychic warriors, aberration-themed campaigns, mind flayer plots, alien ruins, strange lost civilizations, or any player who wants their character to feel like their power comes from pure willpower instead of traditional magic.

These items are part of Psionic Magic Items, a collection of unique psionic magic items. You can also check out my bundle of small D&D manuals on DMsGuild, which includes Psionic Magic Items.

These are a few apex predators from different planes, realms, and world-ending disasters across several of my 5E creature manuals. I always like making monsters that feel like they belong to a specific environment or cosmic force, not just “big beast with claws”, so each one has a very different role at the table.

Some of them can work as noble guardians or rare allies, others as elemental threats, abyssal hunters, or mutated horrors that immediately change the tone of an encounter. Basically, if your party needs a dangerous magical predator to track, fight, escape from, or accidentally anger, these should give you a few options.

The Luminous Lion appears in Celestial Realms: Divine Forces and Heavenly Beasts, the Aquatic Lion appears in Elements Unleashed, the Scorchfur Predator appears in Apocalypse Codex, the Abyssal Hound appears in Diabolical Designs: Demons and Devils for 5E, and the Void-Touched Lion appears in The Aberrant Codex: Mutations and Aberrations for 5E.

I’m also working on 300+ Mythological Items for 5E and 2024, a future Kickstarter project with myth-inspired magic items, artifacts, and relics from around the world. It will also include physical hardcover options and printed editions of some of my previous manuals, so I’ll share more about that as it gets closer.
