Sorry if there is a topic for this one but i could not find it.
So I was leveling new character and when i fought boss in The Tomb of Morditas i died to it while my projectiles were still flying around me. Those projectiles did dmg to the boss even after i died and killed it. Boss dropped some items but when i clicked the respawn button i was presented with new fight thus making it possible to kill it again while dead getting more items and repeating the whole process.
