Let me throw in my 2 cents about her.

Fritili...Fritila...Fri.... ah fuck it, Choco Lily - after bloomed is a very powerful character, even more so if its against multiple enemies. I have her as the finisher (as in: the last girl in line to act) in my DMM team build around crits and skill activation.
Her special - especially if powered up by other girls before she gets to go (blooming ability) - thus reason why she is the finisher, if all girls activate on that turn, can almost double the damage output. Now once the actual Crit mechanic is introduced, you do the numbers.... or dont - simply take my word for it - she is very powerful - and unlike Dendro who looses her umpf after the first turn (granted seldom anything survives that first turn), Frit. just keeps on going, stacking that power up every single turn more and more till it hits the cap.

Yes she is not Kerria level of broken (Kerria is plain and stupid retarded, if this game had PVP this would be an autoinclude character for every whale....then again I dont think if there would be PVP she would be this OP for longer than a month before she would get nerfed drastically.) but as far as huge amounts of damage goes, she is certainly in the uppper echeleons once Bloomed.
