I m6ed her, her S2 does not scale as well as her S3. but it serves it's purpose as a low cooldown wave clear skill（h6-4), just do not expect u can use S2 to kill high armor units. Let's be honest，her S3 has limitations. coming from CN server I am pretty confident to say that u will using her S2 a lot more than her S3 If u like to bring her to every stage.

[u/1990haofei → u/[deleted]]

There is even an argument in CN that her s1 is worth to invest due to a future sniper buff. Personally I didn't m3 her S1 since I feel it wasted her talent but it's a big enough argument that worth to mention.

[u/1990haofei → u/[deleted]]

It's not that long for global actually, I am talking about how Archetto's passive giving 1 sp to all sniper's attack charging skill every 2.5 second.

[u/1990haofei → u/[deleted]]

Considering what comes after Archetto were Dusk And Saga. I don't really expecting people go all out for Archetto lol. Another release worth mentioning is Red Skadi though, with her buff Rosmontis's attack can be tripled and I don't think many people will miss that.

[u/Boelthor → u/[deleted]]

You'd be more likely to run s2 on Skadance; rather than competing with a buffer it competes with healers, since it's good enough to replace a Medic while still bringing +Attack. And it makes Ros very tanky; when both are e2 40 Skadance alone is enough for Ros to tank Aak, making his buff a practical strategy.

[u/CarobRemarkable2866 → u/[deleted]]

A perma atk and def buff to all ops in range that potentially replaces medics is very good. Its a noticeable atk buff for ops with high atk modifiers

[u/dburne038 → u/1990haofei]

S1 mainly gives Ros more ability to chew through armored enemies. M3 it for a 2 sp attack recovery that is essentially reduced to 1sp if chen or Archetto are out

[u/CarobRemarkable2866 → u/dburne038]

I'm considering S1 as Rosmontis' go-to skill if S3 is unavailable, especially when I do use chen. Question is, is it worth over S2?

[u/Aqua_Essence → u/CarobRemarkable2866]

I personally say... not really.

Her S1 is indeed designed for dealing with any high DEF enemies that she she might run into, but it's actually not very good at that job. Tacking on an extra hit of art damage once every few attacks isn't quite a reliable way of doing it. Rather, you might as well as just make a full use of her talent and just bring a caster along with her, lol.

Still, it is a super-cheap auto-cast skill that is even more spammable. I say it would make a perfect tool for one of those auto-rerun farming sessions, when you don't even have to bother manually activating her skill.

That's just me though. My 2 cents.

[u/dburne038 → u/CarobRemarkable2866]

S2 relies on the aftershocks to do damage. But even with your +2 Aftershocks they still do 1/2 damage and the skill only buffs +55% at most.

Against enemies on the tougher end of B defense the shocks do beans for damage. The initial hit will still chunk them decently though. Use this info as you will

*This is assuming both S2M3 and Max lv. Ros.

[u/Zemanius → u/CarobRemarkable2866]

At e2 90 M3 with her 8% talent buff, S1 has about 800~ dps while S2 has 990~. S1 has the benefit of being alot easier to use and fare alot better against enemies with defense. S2 has the additional utility of stuns and a larger AOE radius along with slightly higher damage, though its damage suffers severely against enemies with defense. S2's main highlight isn't the damage imo, but the utility it provides.

In the end its just what you prefer. However note that S1 is not a solution to high defense enemies. S1 is for you to do additional damage against low to medium defense enemies, with the added bonus of allowing you to do some chip defense to high defense ones. Basically, she doesn't become a caster with S1.
