Mummified Hand (AV p. 175)
Property: The hand has one ring item slot that you can use in addition to your own ring item slots. As long as you hold the mummified hand, you gain the benefit and can use the powers of any ring placed on one of its fingers. If two or more rings are placed on the mummified hand, none of the rings function. You cannot benefit from more than one mummified hand.
The hand also gives you an extra hand item slot.
The severed hand of the Prophet Alvito.
