CALAMITY
Cleaving heavy attack
Fateline aims a heavy attack at the tank. It cleaves in a cone.
What to do
Block and do not stay next to the tank.
Mournful Catacomb is the Gilded dungeon in Sorrow's Friend for Night Market. Gilded Fateline's Knell is the only boss.
Very simple fight. The boss goes away at 70% and 35%, and a single person has to follow them while the rest of the group stays in the main room dealing with adds.
Drop Growing AoE away from the group and stay out of Line Beam , Sunburst , and Wrathstorm . At 70% and 35%, Fateline disappears for Aspect of Rage or Aspect of Sorrow , adds spawn in the main room, and one player takes the portal.
If Sunburst hits one player alone, it leaves the crater and extra fire. If one other player stacks on the target, it is only the meteor hit.

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.
