As two actions, you can create this bomb. As an action, a creature can throw this bomb at a point within 5 meters, where it explodes on impact. A cloud of nauseating, yellow fog spreads to fill a sphere twice as big as normal. The cloud spreads around corners, and its area is heavily obscured. The cloud lingers in the air for the duration.

A creature that enters the spell’s area for the first time on a turn or starts its turn there must make a Fortitude saving throw. If the creature doesn’t need to breathe or is immune to poison, the concoction has no effect on it.

On a failure, it spends its actions that turn retching and reeling.

A moderate wind (at least 15 kilometers per hour) disperses the cloud after 4 rounds. A strong wind (at least 30 kilometers per hour) disperses it after 1 round.
