Fake Death

I haven't seen this bug before. It happened to me three times in literally half an hour after I added Berserk Aura to the build.

As you can see why the character dies and loses 0/1 health, while the character still has mana (MOM)

Technically the character is alive, because omen of ammelioration isn't spent and I can still return to the this map.
