Death Spider (Wizard Spell)

This horrible spell causes one of the victim's own limbs to instantly become a mindless, hairy black spider. The spider twists about and starts eating the victim's flesh, doing 1-2 points of damage per round. Anything worn or carried by that limb drops away.
The victim is allowed an initial save against the spell. If it fails, only a remove curse in tandem with a polymorph spell, or a limited wish or more power­ful means, will end the condition. (A dispel magic will be effective only if cast within 2 rounds of the touch that confers the death spider condition.) The afflicted limb can be severed and burned to destroy the death spider. If done within a round of its cre­ation, only a hand or foot will be lost (with 1d4+1 points damage, a system shock roll, and the loss of the limb's mobility and abilities). If left until longer, the entire limb will have to go, with the loss of 1d12+4 hit points and a system shock roll.
A death spider has no poisonous bite or other spider powers, but if unchecked it will inexorably consume its entire host.
One day after the host is entirely eaten, the spi­der will exhibit the web spinning, venom, and other abilities of the spider type it resembles, becoming a giant-sized spider of that type.
The material components of this spell are a small live spider of any sort, a drop of the digestive juices of any creature, and a tooth (from any source).
Notes: Common for drow, who guard it zeal­ously; uncommon for neogi; otherwise very rare.
