The Wand of Unstable Arcane Force (5e Equipment)
From D&D Wiki
Wand, rare (attunement by a sorcerer)
This wand builds up arcane energy from spells you cast. Every time you cast a spell that consumes a spell slot, you gain a charge. The wand may hold a maximum amount of charges equal to your level.
As an action, you may spend at least 1 charge to unleash a bolt of energy at a creature that you can see within 120 feet of you. You deal an amount of force damage to the creature equal to double the amount of charges spent.
Whenever you spend charges roll 1d20. If you roll at or below the amount of charges spent, roll on the Wild Magic Surge table(5e PHB pp. 104).
