You're contradicting yourself (and me), and I was replying to both of you. If I say that spells are unrelated to Perversity and you say that Deep Sleep unlocks Perversity 6, one of us is clearly wrong (hint: it's not me).Unless that means there's a way to achieve Perversity 6 without the usage of Deep Sleep, I don't see how I was wrong. I never said anything about needing the night scenes to unlock Perversity 5, only that you needed it and Deep Sleep to hit Perversity 5+1. I also didn't say anything about spells being related to perversity, nor did the person before me, beyond needing Perversity 5 and Deep Sleep to reach Perversity 6.
I didn't know about Perversity 6 being temporary though, as I've used it multiple times in a row without any problem.
Deep Sleep has nothing, absolutely nothing, to do with this.
