Dragon Staff (5e Equipment)

Staff, rare (requires attunement by a druid, sorcerer, warlock, or wizard)

The staff has 7 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: burning hands (1 charge), fireball (3 charges), or scorching ray (2 charges).
You can also use an action to cast the fire bolt spell from the staff without expending any charges.
The staff regains 1d4 + 3 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff blackens, crumbles into cinders, and is destroyed.
