This cut crystal bottle is filled with silvery liquid. The bottle’s stopper is a single piece of smoky quartz.

One round after you apply this elixir to your skin, it creates an invisible cloud of gas in a 10-foot radius that moves with you and persists for 5 rounds. You are immune to the cloud’s effects, but each round at the end of your turn every other creature in the area with 10 Hit Dice or fewer must make a successful DC 14 Fortitude save or fall asleep for 1 minute. Furthermore, each creature remaining in the area 1 round later (whether already asleep or not) must make a second successful DC 14 Fortitude save or fall asleep for 1 hour. Creatures with more than 10 Hit Dice are immune to the effect.
If you open the bottle but do not immediately apply the liquid, the cloud of gas spreads to fill a 5-foot-radius area, centered on the opened bottle or the place where the liquid was poured out. This cloud persists for 1 minute.
