Illusion Shell

Regular
This illusion makes a chosen object look, sound, and feel different. The base object must be of the appropriate size and shape. The illusion may be disbelieved, but is otherwise stable. However, it will not move about unless the underlying object moves. Damage done by the underlying object is unaf-fected. For example, an illusion shell of a horse could be cast over a wood-en horse. It would stamp, nicker, and smell like a horse, but could not be ridden! Concentration is not required to maintain the illusion.

Duration: 1 minute.
Cost: 1 for an object small enough to be hand-held, or 2 for larger objects. Half that cost to maintain.
Prerequisite: Simple Illusion.

Item
For 200 times the base cost, the spell can be made permanent; it will not be disbelieved!
