People say Labyrinth is hard, they must not have the Demon Layer. Just go one shot sofia until your level can max cap all your stats. Ez pz.
It's necessary to get as many perks as possible. I have a park from the Angel that I get 10% Arousal and Energy every turn so I never run out of energy and with Calm Mind and Cleanse Lust my arousal never passes 25% full.
Well not necessary but helpful
I got my levels from Demon Layer spamming on Sofia ezpz
