This magic item is designed to be worn on the left arm. The wearer can take a "Use an Object" action to activate or deactivate this magic item, making a bladed "arm" protrude from the base.

While activated:

• The wearer suffers disadvantage on all Dexterity(Stealth) checks, as the item emits a magical buzzing noise.
• The wearer can attack with the bladed arm, provided they are not holding an item in their left hand, dealing 2d8 Piercing Damage. This attack counts as Finesse, and if you are attuned to this item, you also have proficiency.

"A prototype weapon,  partially infused with magic to allow for high-damage takedowns, albiet at the cost of stealth."

Notes: Damage: Piercing, Stealth Disadvantage: Impose
