Wand of Fireballs
Source: Dungeon Master's Guide
Wand, rare (requires attunement by a spellcaster)
This wand has 7 charges. While holding it, you can use an action to expend 1 or more of its charges to cast the Fireball spell (save DC 15) from it. For 1 charge, you cast the 3rd-level version of the spell. You can increase the spell slot level by one for each additional charge you expend.
The wand regains expended charges daily at dawn. If you expend the wand's last charge, roll a d20. On a 1, the wand crumbles into ashes and is destroyed.
