Defeating Gilded Fateline's Knell grants this reward:
You have the gift of life! When you die, you instead become immune to damage and negative effects. After 4.5 seconds you are brought back from the dead, healing for 16000 and radiating out a wave of renewal energy dealing 50000 Magic Damage and stunning enemies for 5 seconds. This can occur only once. Rebirth only lasts 15 minutes and only takes effect within the bounds of the Night Market.
