Agni

You have resistance to fire damage while you hold this staff.

The staff has 4 charges. While holding it, you can use an action to expend 1 or more of its charges to cast fireball from it, using your spell save DC. Using more charges adds 1d6 per charge expended to the damage.

This staff amplifies the power of your fire magic, whenever you cast a spell with the fire damage type, it is cast as if from a spell slot higher.

The staff regains 1d2 + 1 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.

Notes: Resistance: Fire, Druid, Sorcerer, Warlock, or Wizard, Damage, Control, Combat, Warding
