With the exception of Lust, I feel like ~30 Debuff+ Grail buff was enough to get your debuffs to ~100%. I think there was a resist here and there, but.

Even Dark Lilim is constantly resisting my debuffs. Like, it is not rare that only one of my three Def debuffs (A, B, B if first B resisted) goes through. No Grail buffs there, but geez.
