Poison

Uncommon (Inhaled)

When released, this poison fills a 10-foot radius around the source. You can accurately throw a vial of it (shattering on impact) at a point up to 30 feet away, or release it by other means. A creature subjected to this poison must make a Constitution saving throw with a DC equal to the crafter's Poison DC.
On failure, they take 2d4 Poison damage and become Poisoned for 1 hour. At the end of a poisoned creature’s turn, it can repeat the saving throw, ending the condition on success.
This effect lingers in the area it was released for 1d4 rounds. A strong wind will clear away and disperse the poison. A creature that enters the area for the first time must save against the poison.
