Lost resolve while having prayer beads boon.

Prayer beads did not stop my resolve from being damaged. I was on an amazing run and got relaxed thinking I was invulnerable for a room. Obviously I was wrong.

I believe this was from an on death effect, such as the orbs that chase you before exploding.

Does look like your character died. (Not Resolve, but life wise)
I think if you "really" die your resolve will go to zero aswell.

But that is only my guess.
