So i just casually played in ppl with this mode and got (bug or maybe its been secret) domain fusion where you fusing the sightless: traitor for salvation (one with madness area) and random guy with [Empty] area. When i started to fuse it red text apeared: make the enemy in area se true void. Any ideas on it?

P.s. forgot about it: then i fused it and activated area my game crushed and i never got that again
