You have resistance to acid damage and your equipment is immune to acid damage while you hold this 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: beluud's corrosive caress (new) (1 charge), melf's acid arrow (2 charges), glistening acid slick (new) (4 charges), water to acid (new) (4 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 dissolves into slime and is destroyed.
