You have resistance to fire 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: Burning Hands (1 charge), Fireball (3 charges), or Wall of Fire (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 blackens, crumbles into cinders, and is
destroyed.
