You have resistance to poison damage and you have advantage on saving throws against poison while you hold this staff made from gnarled and knotted wood.

The staff has 10 charges. While holding it, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC: protection from poison (2 charges), ray of sickness (1 charge), stinking cloud (3 charges), or toxic breath (new) (3 charges).

The staff regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff evaporates into purple gas and is destroyed.
