Very easy floor than most of them. Just need a good team (mine kinda budget too kekw)
Phase 1: Kill ads, Lilibet deals 50% of ur max hp as extra dmg , as long as u healthy (above 30%) she can never kill your team. (prefer to have buffs all the time for lilibet but its not really needed and fights are kinda easy)
Phase 2:
List to remember
1) Non atk will give straze's curse debuff on the unit, u have to atk after doing non atk ( you cant tama s3 s2, so u must s3 s1) if u do, you get full team strip and stunned.
2) When straze is buffed, he gain cr when attacked.
3) Straze has a buff where it become stronger when he takes a turn, to remove it, you must crit him (twice i think?) with single target atk
4) Straze s3 deals max hp dmg but is reduced with the amount of buffs you have, buff up when straze going to s3.
5) Straze at 40% hp become Fastus, He now gain anti crit every turn and every non crit u do has a chance to get atk buff when attacked AND reset his s3 CD by 1 turn.
6) Straze (both form) ALWAYS full cleanse after he move
7) Straze s3 on Fastus form does def pen if he has higher atk than the target, best to strip his atk buff or dont give him (if his going to s3, hit ads)
8) You must not have any buffs when Fastus s3 else it will change to a random debuff. (Tama can just cleanse it on idol tbh)
9) Straze s3 gets stronger on every use
beside that its pretty nice and straightforward fight.
