Shield of the Warrior Maiden

Armor (shield), rare

So long as you hold this shield, you automatically know the physical status of any creature you can see within 30 feet. You know how badly injured they are, if they are dying, or if they are merely playing dead.

In addition, whenever you are adjacent to a prone ally at fewer than its maximum hit points, or a prone ally suffering from any condition, you can spend your reaction to grant your shield bonus against melee or ranged attacks targeting them. You can use this ability even if you cannot see the attacking creature.
