Dismembered

You have had a hand physically severed, but not truly, removed by a magical effect. Though you have lost your hand, your hand continues to function. 

• You cannot use weapons or use items that require two hands, and you have disadvantage on ability and skill checks to perform actions that would normally be performed with two hands. 
• You gain the ability to cast the find familiar spell without expending a spell slot or expending material components. When you cast this spell you summon your own dismembered hand. You cannot cast find familiar again in this manner until after you have completed a long rest. The hand has the statistics of a crawling claw and otherwise behaves as a normal familiar. You may have your hand and a standard familiar at the same time. Any feature or ability that effects your familiar also effects your hand. 
• Your hand does not disappear until a minute has passed after it has been reduced to zero hit points. If your hand is at zero hit points you may use an action to spend a hit dice. Your hand heals an amount equal to the result. If a minute passes while the hand is at zero hit points, the hand disintegrates and disappears. 
• Your hand makes all skill checks and saving throws using your bonuses instead of the bonuses of a normal crawling claw. It makes all skill checks with disadvantage.
