History of Dark Motes

Dark Motes are a collectible in the Prophecy dungeon. They are dropped by Knight Echoes (a Taken Knight variant) when you are standing in shadow, and they are deposited at the black pillars to cleanse them.

Collection

Standing in shadowed areas drops Dark Motes, while bright areas drop Light Motes. The wisps at the edge of the screen show which type you are in. Collecting one type replaces any motes of the opposite type you are holding. Motes last 30 seconds.

Depositing

Collecting exactly five Dark Motes triggers a carry phase. The camera moves to third-person, you hold a large mote, and you cannot use weapons. Bring it to the black pillar within 30 seconds and fire to disperse it. Dispersing both matching pillars opens the door to the next pair.

In the Hexahedron fight, a probe indicates which pillar to use. In the Kell Echo fight, dispersing a matching pillar after collecting enough motes makes a Kell Echo copy flee.
