Bastion of Duplicity (Exalted)

While holding this shield, you have a +3 bonus to AC. This bonus is in addition to the shield's normal bonus to AC.

While attuned to this relic, the wielder's Charisma score becomes 26 and once per day, the wielder can use this relic to cast Major Image, Programmed Illusion, and Glibness.

Also, when successfully struck by an attack, roll a d20.  On a 1, you take double damage.

Shields require the Utilize action to Don or Doff. You gain the Armor Class benefit of a Shield only if you have training with it.
