Armblade Claw

A claw is a simple, bladed melee weapon worn as a glove.

An armblade is a magic weapon that attaches to your arm, becoming inseparable from you as long as you're attuned to it. To attune to this item, you must hold it against your forearm for the entire attunement period. As a bonus action, you can retract the armblade into your forearm or extend it from there. While it is extended, you can use the weapon as if you were holding it, and you can't use that hand for other purposes.

Special: Attached. You can't be disarmed of this weapon, but donning or doffing the weapon takes an action. You can use a hand equipped with a claw to hold items, but can't attack with the claw while doing so. Additionally, you have disadvantage on attack rolls using other weapons held in your clawed hand.

Light: A light weapon is small and easy to handle, making it ideal for use when fighting with two weapons.
