Bone blight

Bone blight was an arcane spell from the schools of alteration and necromancy that allowed a wizard to erode the victim's bones.

Powers
The spell's magic caused the victim's bones to slowly melt away, turning them into a mound of flesh. This spell had no effect on the undead. The victim's bones became brittle and susceptible to breaking during the first day after casting. After the first week the victim experienced painful bone fractures until eventually the bones dissolved, leaving the victim as a mound of flesh and dying painfully. Naturally healing was impossible while under the effect of bone blight, and magical healing merely slowed the excruciating process.

Components
In addition to verbal and somatic components, this spell required as a material component a drop of aqua regia to cast.

History
This spell was found within the Book of Shadows, a tome based upon the oration of the necromancer Nebt Bhakau of Zakhara.
