Abate Dracorage

The longer a Dragon Magi fights, the angrier and more determined they become, the more power they draw from within themselves - an emotional powersource. This is why the Abate Dracorage spell was created, specifically to fight against Dragons. Upon casting this spell, the rage will drain from the targeted Dragon Magi, and as they calm their power levels will drop, rendering any Dragon's Rage magic completely ineffectual.
