Miracle of Grimnir gives all players a 20% maximum health buff if the marked monster is killed. However, if a player is dead, they will miss out on this bonus.
I don’t think it used to work this way, so maybe something broke in an update.
Steps to Reproduce (Required):
Buy Miracle of Grimnir
Start map. Have someone die while the marked boss is still alive
Slay the boss
Take note: all alive players will receive an increased maximum health buff, while the dead player will miss out on it permanently
Grimnir also appears not to bless you if the boss forgot to exist. We were fighting one in the Citadel of Eternity when it up and vanished in front of my eyes (not ledged, not killed normally) and none of us received the max HP buff. He seems very finicky about what’s worth a blessing.
