No where in the in-game documentation says this item is one time use. Please update that. Very frustrated at the moment.

Not everything needs to be mentioned in the manual, and this, in my opinion, is obvious enough not to be a problem.
Sorry.

How is this at all obvious? It looks like and physically acts like a wand in the world. Wands don't disappear. It would take 10 seconds to add it to the in game book.
