Spell: Wither

It appears that although Regenerate is a spell in D&D edition 3.5, the corresponding "Wither" spell has been excluded. So although there's a convenient way to attach limbs, there's no specific magical way to remove them. Hence the entry below.

Wither Limb

Necromancy

Level:	Clr 7, Drd 7, Sorcerer/Wizard 7
Components:	V, S
Casting Time:	1 standard action
Range:	Touch
Target:	Living creature touched
Duration:	Instantaneous
Saving Throw:	Fortitude negates (harmless)

The subject’s bodily extremities (arms, legs, tails, or even extra heads on multi-headed creatures) shrivel and fall off. After the spell is cast, the physical degeneration is complete at the end of 1d4 rounds.

Withering also causes 4d8 points of damage +1 point per caster level (maximum +35). It is equally effective on all creatures which have bodily extremities including nonliving creatures such as golems or undead.

Casters wishing to invoke this spell verbally invoke a curse or speak a word to remove bodily integrity, while forming an unwholesome gesture with hands or posture.
