You have resistance to necrotic damage and you have advantage on saving throws against disease while you hold this ashen gray staff.

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: blindness/deafness (2 charges), contagion (4 charges), harm (6 charges), or spasm (new) (1 charge).

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