Staff of Flame

The staff has 5 charges. As an action; expend 1 or more charges to cast a spell from it, using your spell save DC and spell attack bonus: burning hands (1 charge), chromatic orb (fire version only, 2 charges), or scorching ray (3 charges).
You can also use an action to cast the fire bolt cantrip without using any charges.
The staff regains 1d4+1 expended charges at dawn. If you expend the last charge, roll a d20. On a 1, the staff blackens, crumbles into cinders, and is destroyed.
