For the Godhunter mythic path from Mythic Paths of the Lost Spheres:
Feed the Fallen (Mythic)
You offer your Detria to the remnants of the spirit within you kindling its failing powers to new life.
Prerequisites: Gather Detria mythic power
Benefit: You may use your Detria to restore power to a spirit’s expended ability. The Detria must be of a spell-level equal to or greater than the spirit to be restored and is consumed by this feat. The exhausted ability can only be restored once per spirit until a normal cooldown period has passed again for the ability.
