Last one, since thread is no longer active. This is original, just like my first post:
You open up a crate to find...
A large, black-steel goblet and a canteen of holy water. A singular ring of silver, embedded with glowing onyx stones, wraps around the mouth of the cup.
As you pour the holy water into the unholy grail, you are surprised as the water explodes into a brilliant green fire. The fire is warm to the touch, not hot, and exudes a dark purple mist.
Drinking the fire from this goblet will transmogrify you into an animated skeleton. You will, however, be granted eternal life so long as you drink from it once every month.
