You have a +2 bonus to attack and damage rolls made with this magic quarterstaff. When you hit with a melee attack using this staff, you can expend 1 charge to deal an extra 1d6 force damage to the target. Additionally, while holding it you gain a +2 bonus to AC, saving throws, and spell attack rolls.
Spells. While holding this staff, you can use an action to expend charges to cast one of the following spells, using your spell save DC and spell attack bonus: magic missile (1 charge), __ray of enfeeblement_ (1 charge), __levitate_ (2 charges), __hold monster_ (5 charges), __lightning bolt_ (5th-level version, 5 charges), __wall of force_ (5 charges), __cone of cold_ (5 charges), __fireball_ (5th-level version, 5 charges), globe of invulnerability (6 charges).
The staff has 20 charges and regains 2d8+4 expended charges each dawn. When the last charge is expended, roll a d20. On a 20, the staff immediately regains 1d8+2 charges. On a 1, the staff loses its magical properties, apart from its +2 bonus to attack and damage rolls.
Retributive Strike. You can use an action to destroy the staff, releasing its magic in a 30-foot-radius explosion. Roll a d6. On an even result, you teleport to a random plane of existence and avoid the explosion. On an odd result, you take damage equal to 16 × the number of charges in the staff. Every other creature in the area makes a DC 17 Dexterity saving throw . On a failed save, a creature takes damage based on how far away it is from the point of origin, as on the Retributive Strike table. On a successful save, a creature takes half as much damage.

|---|---|
| 10 feet away or closer | 8 × charges in the staff |
| 11 to 20 feet away | 6 × charges in the staff |
| 21 to 30 feet away | 4 x charges in the staff |
