Nightmare Act 3 Quest 6
Frozen, Fire Chain, teleporty guys with big swords in a tight staircase with no kiting room

Almost got out XD
Fire Chains have been by far the hardest mod to deal with so far. Fire Chains, Arcane is hilariously annoying to dance around XD Especially when it comes on a naturally fast and wiggly mob like scavengers or those wraiths.
Next!! God I love HC XD. Shooting for Hell!
