Light Motes

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

Collection

Your position decides the mote type: standing in bright areas drops Light Motes, while shadowed areas drop Dark 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 Light 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 white pillar within 30 seconds and fire to disperse it. Dispersing both matching pillars opens the door to the next pair.

In the Phalanx Echo fight, light and shadow positions shift after each pillar is dispersed. In the Kell Echo fight, dispersing a matching pillar after collecting enough motes makes a Kell Echo copy flee.
