Flask of Curses
This item looks like an ordinary beaker, bottle, container, decanter, flask, or jug. It may contain a liquid, or it may emit smoke. When the flask is first unstoppered, all within 30 feet must make a DC 17 Will save or be cursed, taking a -2 penalty on attack rolls, saving throws, and skill checks until a Remove Curse spell is cast upon them.
