As an action, you can create a vial of liquid that contains three easy-to-miss bubbles shaped like Zs. A creature can drink the contents as an action. The creature must make a Fortitude saving throw.

On a failure, it is falls unconscious for the duration.

This effect ends for a creature if it takes damage or someone uses an action to shake or slap it awake. Additionally, a creature can repeat the saving throw each minute or if it hears an extraordinarily loud noise such as the thunderwave spell, ending the effect on itself on a success.

Undead and creatures immune to being charmed aren’t affected by this spell.

Augment

Sleeping Gas. You can expend 1 additional catalyst to so the potion is in gas form. As an action, a creature can throw this vial at a point within 5 meters, shattering it on impact. Each creature in a sphere centered on that point must make the Fortitude saving throw.
