History of Court of Jesters

Court of Jesters is a 15-point triumph in the Kingslayer seal: complete all encounters in the King's Fall raid with a full fireteam of clanmates.

How to complete

1. Get six players who are all in the same clan. Shacknews: "Ensure that everyone in your Fireteam is in the same clan and this one will activate."
2. Finish the whole raid. TheGamer says any difficulty works and there are no weapon or subclass restrictions.
3. If your clan can't field six, join a clan temporarily for the run.

Seal

Part of the 21 triumphs needed for the Kingslayer title, which also include elemental, challenge and Master-difficulty triumphs that can often be combined in one run. Both guides predate later changes to the raid, so check in-game that the triumph is still tracked.
