Hint for anyone that might wanna try doing this: at uptie 4 her defense skill becomes Sloth flavored, so you can use it a couple times early to generate resources for Effervescent Corrosion (which does not use Gluttony resources so you can use it to generate it resources for G Gregor passive) and for G Outis, Lcb Meursault and T Corp Don. Obviously this is unecessary if you get a ego resource relic early on but rng isnt always at your side.
Makes sense cuz under normal circumstances you see the S3 once or twice during a fight (Non-solo) but the S2 you can see it more frequently but not as frequently as S1. If the identity only cool skill is its S3 the id will be just bad to play with through most of the fight except for a couple times, even ids with super broken S3s like Rabbit cliff have good S2s
