Wither Limb
By the power of Rot I Corrupt you and wither your <name of limb>.
This spell causes the target’s limb named in the spell to become a wither husk, and useless until it is restored in some manner or until the spell expires after one day (at spell reset).
When casting the spell, the target must be a limb of the creature capable of function and support.
For example, on a humanoid target the only limbs available would be the Right Arm, Right Leg, Left Arm or Left Leg.
The Target is free to otherwise move about; as best they can be depending on which limb was withered.
