Can the Fel/Fire/Shadow Energies be used to heal/shield in WoW?! I need it for something. The Ember Tap is capable to restore HP . Also when you sacrifice your demon this allows you to be shielded for 200% of the amount sacrificed?! What about Fel Energy ?! When Ember Tap becomes green warlocks use its Fel Version. What about Shadow Energy ?! Is Vampiric Aura a Shadow Spell ?! Or Fel Spell ?! I need answers please !!
