This strange item consists of an animated arm and three-fingered claw attached to a heavy leather belt reinforced with strips of metal.

As its most basic function, a spare hand can grasp or carry any object you could normally carry in one hand, freeing your normal hands for other tasks. A spare hand can hold magic items such as wands and rods for easy access, but you cannot activate those items while they are so held. Transferring an item to or from a spare hand is a free action. Whenever your spare hand is not carrying an item, you gain a +2 competence bonus on Climb, Escape Artist, and grapple checks.
Without further augmentation from an infusion (see below), a spare hand cannot do anything other than hold an item—it cannot wield a weapon, retrieve a stored item, or perform any other task.

If you power a spare hand with a 1st-level infusion (see the EBERRON Campaign Setting), it gains additional qualities. Once per round, you can command the hand to stow an item or retrieve a stowed item (including a weapon) as a free action. If you instead expend a 2nd-level infusion, the spare hand gains the above ability and can also hold a buckler or light shield, freeing your normal hand while still providing a bonus to AC from the shield. You still incur any armor check penalty or other drawbacks of holding the shield, and are subject to normal penalties if you are not proficient with the shield. If you expend a 3rd-level infusion, a spare hand gains all the above abilities and becomes capable of wielding a light weapon. You can command a spare hand to make off-hand attacks with this weapon as if you were wielding it. A spare hand attacks using your normal attack modifier plus any appropriate penalties for an off-hand attack.

Using an infusion to power a spare hand requires 10 minutes and the expenditure of an infusion of the appropriate level. An infusion powers a spare hand for 24 hours.
