Wand of Lightning Bolts

Wand Magical Rare (this item requires attunement)

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 Lightning Bolt 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 1d6 + 1 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.

Lightning Bolt

A stroke of lightning forming a line 100 feet long and 5 feet wide blasts out from you in a direction you choose. Each creature in the line must make a Dexterity saving throw. A creature takes 8d6 lightning damage on a failed save, or half as much damage on a successful one. The lightning ignites flammable objects in the area that aren’t being worn or carried. At Higher Levels (With more charges): When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot above 3rd. (Each extra charge)
