My lvl 100 HC character was killed by an after death effect from the new pit boss, Mother’s Judgement. Instant kill after loot was on the ground. The same projectile hit me during the boss fight and seemed to do only a few thousand dmg then. I had 20k+ life but at that point no active defenses up.

In general, the pit feels much better balanced for HC this season, but it would be nice if someone were assigned to assess each patch for HC issues.
