Divine Magic : Death Flame

Death Flame is a type of divine magic that is considered the only good-aligned magic of its kind. It requires a great deal of willpower to use and is said to come from Flax The Greater, the God of the Heart. The magic imbues the user with a small portion of Flax's powers, but the strength of the magic is amplified by the user's deep belief in Flax.
The magic takes the form of a bright, golden flame, and is often used to heal the injured and to ward off the forces of darkness. It is said that the flame has the power to purify and cleanse, and those who possess the magic are often seen as protectors of the innocent.
The use of Death Flame requires great responsibility and discipline, as the user must be in complete control of their willpower and their emotions in order to wield it properly. Those who are able to master the magic are highly respected and revered within their communities, and often serve as leaders and healers.
