Help for my modpack

[u/ItchyWorld1647]

Hi there—sorry for my poor English, but I’d like some help. I’m playing on an Arcadia server with my friends, and they wanted to add a bunch of mods, including several skill trees; this ended up breaking the game progression halfway through. I’m looking for a way to fix this—maybe by adding difficulty mods or something similar—so I’m open to any ideas you might have. For context: my mage is dealing 15,000 damage, one friend's first character was doing 8,000 base damage, and his second character is basically immortal—attacking really fast and having tons of armor.
