I've tried searching for this because I figured it would have already been asked, but couldn't find anything.

How would I create a custom Bound Items spell?

I know how to create the weapon/armor in the CS, and I know a little scripting, though I'm a bit rusty on that end. But how would I add them to a bound-item spell that mimics the vanilla game spells, including the removal of currently equipped items and re-equipping them once the spell ends?
