Vial of Lichbanepotion, very rare

When thrown this vial of watery red fluid explodes into a fine mist with a radius of 30 feet centered on the point it was thrown. Any undead in this area is Stunned. At the beginning of an affected creature’s next turn and every turn afterwards it can make a DC 12 Constitution saving throw to end this effect. Additionally, a lich that is exposed to this effect takes an additional 30 days to rejuvenate the next time it dies.
