Yuppie Water is a one-shot treasure card.
"Use during any combat. Usable once only, and only to help Elves, +2 to each Elf in the battle."
Yuppie Water is a one-shot worth 100 Gold. It is very powerful if there are many elves in the battle, reaching up to heights of +6, but without Elves, is useless. It also can't help monsters, only players. It won't be much of a loss if you just pass it away.
