Armor (Shield)

Rare Requires Attunement

This silver shield is polished to a mirror finish. Its front is made from a pair of metal doors with lion-headed fixtures. Reflections seen in the shield's surface appear distorted, as if they're seen through a strange fog. While attuned to the shield, you suffer none of the appearance or frailty of old age, although you can still die from it. The shield has 4 charges and regains all expended charges daily at dawn. While holding the shield, you can cast either dimension door (4 charges) from it as an action, or misty step (2 charges) as a bonus action. When used to cast a spell in this way, the shield's doors open up to reveal a swirling portal through which you, the shield itself, and any other teleported creature or object are pulled as part of the spell. The doors close again when you reappear in the new location.
In addition, while you're attuned to the shield, a creature can use it as a tuning fork required for the plane shift spell, although the shield itself can't be used to cast the spell. You must be a willing creature that's also targeted by the spell in order for it to be used in this way. The shield can be magically attuned to any plane of existence you choose as part of the spell, which you determine at the time the spell is cast.*
