You have advantage on saving throws against curses and against being petrified while you hold this eerie staff made of petrified 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: bane (1 charge), bestow curse (3 charges), jinx (new) (4 charges), or remove curse (3 charges). You can increase the spell slot level of bestow curse by one for each additional charge you expend.

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 white mist and is destroyed.

Curse. This staff is cursed, and becoming attuned to it extends the curse to you. The identify spell is deceived by the curse and falsely omits the curse from the properties it reveals about the staff. As long as you remain cursed, you are unwilling to part with the staff, keeping it within reach at all times. In addition, you have disadvantage on all saving throws except those against curses and against being petrified, and any creature within 60 feet of you that tries to use magic to remove a curse or end the petrified condition must succeed on a DC 15 Charisma saving throw or the magic fails. The curse upon you can be removed if you are targeted by the remove curse spell or similar magic, but only after the staff has been destroyed.
