What it is:
A bow that self deletes after specified time.
Timer countdown shows in weapon attributes list.
Message sent to player when item deletes (meant to avoid player confusion when the item deletes).
 

Why?
This is my solution to giving players an over-powered item and making it so they can't keep it forever.

Note:
*** If you change the timer, be sure to do it for all three.

If you want the timer to show up at the bottom of the attributes list instead of under the name, find AddNameProperty (there's two of them) and change to GetProperties
