I should've been more specific! I meant when you have the armor/weapon/whatever and use the spell (I intend for these to be only one cast), that the item will not poof.
Funky's answer is the easiest way to do it. Make the power use 2 charges, and give the item 3. It'll be able to be used once, after which charges will decrease from 3 to 1. Then it won't be able to be used anymore, since a second use would require more charges than it has left. Because it has one charge left, it won't be destroyed.
