Wand of Dispel Magic

Wand, rare (requires attunement by an arcane spellcaster)

This wand has 7 charges. While you hold it, you may use an action to expend one or more charges to cast a spell. By expending one charge, you may caste dispel magic as if with a third level spell slot. For each additional two charges expended, the spell is cast at one spell slot higher.

The wand recovers 1d6+1 charges each day at dawn. If you expend the last charge, roll a d20. On a 1, the wand’s magic cancels itself out, turning the wand into a mundane stick.
