Reporting this sort of second hand.
My son just created a level 1 artificer, completed the grotto, then realised after completing 2 other quests that he still had Protection from Death on his buff bar while he was standing in the village.
He managed to complete 2 more quests before a mob feared him.
From that point on he was helpless and unable to die!!!
Logging out and back in sorted the buffs.
I didnt experience this myself when I played my wizard earlier so im wondering if it has something to do with the changes to artificer infusions cast on equipment.
