Devil's tail

Devil's tail was a transmutation spell that gave the caster a tail.

Effects
On casting devil's tail, a tail grew from the caster's body. This black or red 3-foot-long (91.44 cm) tail was spiked at the end. This tail's value lay in its potential as a weapon. The caster had it so well under control that it could be employed as a weapon even in conjunction with other hand-held ones. However, doing such a thing was detrimental to the accuracy of the attacks. The spell had a minimum duration of an entire minute and lasted longer the stronger the caster was.

Components
The casting of devil's tail required somatic and verbal components.

History
The only known way to obtain devil's tail was through the Diabolic domain, a suit of spells that was not granted by all infernal entities.
