Lostbelt No.5.5 - Hell Realm Mandala - Heian-kyo Gourai Issen
Section 13 - Arrow 3
An assisted solo with Waver's help as this is probably the hardest fight this chapter.
Another Boss fight with interesting mechanic. Every turn, Ibuki will gain a layer of B, A, Q and NP dmg invul stacks for her 1st and 2nd HP bar. Once you break her 2nd HP bar, she will turn all stacks into extra HP for her 3rd HP bar, but will stop gaining these layers every turn.
Invul Pierce CE / Servants are strongly recommended here.
Her NP also applies Invul Pierce before dmg so be careful.
