How can I beat the strap‑on demoness (3rd demon general)? No strategy is working — she keeps healing way too fast!
Put all your skill points (tab to the left of Ability points) into Arcane. Also bring a Light potion with you, you'll want to keep her frozen as much as possible. I let the Celestian meter charge all the way to the top at the start by tediously paging through the sex cutscene at the start of the battle.
