Eidolon

The Eidolon is an Elementalist boss found in the Iron Mines of Moladune, Ring of Fire and Abaddon's Mouth missions. There is also an NPC very similar to Eidolon called Ice Beast in Mineral Springs.

The player is told to kill the Eidolon during the Iron Mines of Moladune mission. During the Ring of Fire mission, defeating the Eidolon completes the secondary objective. In Abaddon's Mouth mission, killing the Eidolon is optional and not considered part of the mission itself.

Defeating the Eidolon and returning its Spectral Essence to the Ancient Seer allows the player to have their armor infused.
