Dust of the Mummy

This poison is created during a mummy's embalming process, distilled from the dead creature's removed organs. A creature subjected to this poison must succeed on a DC 12 Constitution saving throw or be cursed with mummy rot. The cursed creature can't regain hit points, and its hit point maximum decreases by 10 (3d6) for every 24 hours that elapse. If the curse reduces the creature's hit point maximum to 0, the creature dies, and its body turns to dust. The curse lasts until removed by the remove curse spell or similar magic.

Poison: Poison use is controversial or even illegal in many societies due to the often subtle and deadly nature of poisons. Check with your GM before purchasing poison to determine which poisons are allowed in your game.

Inhaled: These poisons are powders or gases that take effect when inhaled. Blowing the powder or releasing the gas subjects creatures in a 5-foot cube to its effect. The resulting cloud dissipates immediately afterward. Holding one's breath is ineffective against inhaled poisons, as they affect nasal membranes, tear ducts, and other parts of the body.
