Properties
When drunk or applied to the skin, the user must make a DC 12 Constitution saving throw, becoming paralyzed for 1d4 rounds on a failed save as their muscles seize up. On a success, the user's melee attacks deal 3 additional damage for 2d6 rounds. After this time, the user gains one level of exhaustion, regardless of the saving throw result.
