Find Zaeim. Find Zaeim or Priest Sazeer in Champion's Dawn. Follow the "trail of dead" to locate the Awakened Sunspear champion. Get the coin from the Awakened Sunspear. Enter the cave. Search the cave for the Awakened Sunspear Champion. Defeat Koss.

Use your springer to get atop the platform where renown heart NPC Priest Sazeer and Elder Priest are overlooking Champion's Dawn. They can be found directly south of the Champion's Dawn Waypoint, at the renown heart icon on the map (south of the Mastery Point at the top of the high rock pillar). There are ladders leading up to them, but these are not interactable and you need to use the Springer. Speak with them, and then head south down to the shoreline, reaching the cave entrance to the Grotto of the Defeated. Follow the dead bodies to the instance marker and enter the instance. Inside the instance, interact with the chain by the gate to open it. After some dialogue, the elite Awakened Koss Dejarin will fight you: Try to fight him adjacent to any Slimy Rock — the skill provided by these objects acts as a quick CC sufficient to break his defiance bar on demand. Don't attack him with his shield up, he will reflect projectiles back at you. A stun break may prove useful, as he will occasionally fear you by shouting his name. The mission is complete once the remaining dialogue plays out.
