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. The energy flow is
disrupted when in combat, however 'Energy revival' will allow a certain amount
of healing to still happen. 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.
