Death Magic

Death Magic (死の魔法 Shi no Mahō) is a Black Art utilized by Zeref.

Description
Death Magic is a Black Art Magic which gives its users the ability to cause any living thing around them to die. Sometimes this magic is uncontrollable, causing it to burst out randomly, killing anything within a certain radius around the caster. However, when the weight of life is forgotten and the user fails to care about people's lives, it allows him to fully control the Magic at his will. Certain things can protect people from this spell such as Natsu Dragneel's scarf.
