Type of feat: Spirit-eater
Prerequisite: Devour Spirit; must have restored the Wood Man
Required for: None
Specifics: You effectively reverse your ability to drain spirits, instead converting some of your spirit energy into HP for you and your companions. This ability fully heals all companions and raises any who have fallen unconscious. The amount of spirit energy it costs is proportionate to the amount of damage healed, to a maximum of one complete stage of the spirit energy bar. This ability can be the most potent way to reduce Craving as well - it causes you to lose an amount that is also proportionate to the amount of damage healed.
Use: Activate
