My attempt at a wizard spell - Armor Transposition

[Silva Stormrage]

This is surprisingly awesome, especially when used to nullify class features. Also, potentially hilarious. I suggest that the material components be a slug and a snail.

A slug and a snail would be somewhat hard to keep in a spell component pouch. Alive at least

Though this is an interesting spell. I would suggest making it target more creatures. Maybe 2 creatures plus one per 3 or 4 caster levels above 5. You need to compare this spell vs slow, stinking cloud, and other similar third level spells. Or maybe reduce the spell level to level two.

Also a question. What happens when you switch say, a ogre's suit of full plate to an ooze or another large sized creature that can't wear normal armor?
