This Prosthetic Arm moves as if it were a standard arm with the same motion and mortar function to the user. The component does not feel pain and crashes small items with its enhanced strength quite easily. The arm has runes carved around it that form a very small/passive anti-magical barrier preventing the item from being dispelled. This anti-magical barrier can not be copied down or replicated by any spell caster.
The arm also has a force energy attack feature, when the wearer takes damage they can use a reaction to release a wave of force energy around them in a 10-foot radius and pushes the attacker back 5 feet. The attacker makes a dexterity saving throw, on a successful save the attacker takes half damage and does not get pushed back, on a failed save the attacker takes full damage and gets pushed back. The damage dealt is 1D10.
Notes: Damage: Force, The arms runes recharge over a period of time
