A riftwalker can heal their entity by drawing rift energy from the void and focusing it on their minion. Knowledge of rift energy flow is known to help the effect of this spell. It also works on other riftwalker entities, allowing you to assist in the regeneration of anothers entity. If a riftwalker casts this spell on his/her own magic entity, the spell will be reflected back on the riftwalker, healing him/her. The more knowledge of 'Energy revival' the magic entity has, the more the spell will heal the master.
