The blighted

More or an anti-druid than a true druid, blighted Druids have more in common with necromancers than others of the druidic path. Separating themselves from the natural world, they can take on unnatural states and steal life with a vampiric touch. Simply moving through a forest causes vegetation around blight druids to wilt and die.

Who knows what dark road blighted druids went down to lead them to hate nature they way they do. For the sake of the world, one would hope it happens to no other.
