When an item is set to have charges, whether it be 1 or
infinate, once it is right clicked one time it poofs as if its
set to be expendable, but it poofs before the spell casts
so you cast the spell as if its being cast by you and not
the item because the item no longer exists. I tried it
with all sorts of combinations of charges, maxcharges,
and Spellcharges settings and either got that or item out
of charges.
