Champagne of Risk

Any creature that enters the pool of champagne of risk experiences a rush of good luck and must succeed at a Will saving throw each round or give in to the supernatural fortune, which is as intoxicating as it is fickle. Whenever an affected creature makes a d20 roll, it rolls twice and takes the better result. The effect is unstable and only lasts while the creature remains in the pool, and for 1 round while outside it. A creature affected by the pool cannot be affected by it again for 24 hours. If a creature rolls a natural 20 while under this effect, it loses its benefits and instead suffers a –4 penalty on attack rolls, saving throws, skill checks, and concentration checks for 1 day. This is a curse effect. Creatures under the effect of the life bubble spell are unaffected by the pool's fumes.
