Staff of Earth, Variant (5e Equipment)

Staff, rare (requires attunement)

This staff can be wielded as a magic quarterstaff that grants a +2 bonus to attack and damage rolls made with it. While holding it, you have a +2 bonus to spell attack rolls.
The staff has 10 charges for the following properties. It regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff loses its properties and becomes a nonmagical quarterstaff.
Spells. You can use an action to expend 1 or more of the staff's charges to cast one of the following spells from it, using your spell save DC: catapult (1 charge), meld into stone (3 charges), stone shape (4 charges), stoneskin (6 charges), or wall of stone (5 charges).
You can also use an action to cast the mold earth spell from the staff without using any charges.
