By the end, I was killing everything in two or three turns. Projective Link is dangerous, because some hits teleport you or add extra damage/effects. I came close to the edge a few times towards the end, but I was dealing 20-30k bonus damage with Astrostoicism before other bonuses. Humbaba worked well, but sometimes the self-inflicted bleed effect was negated by high will power before I could convert it into healing.
