As an action, the wearer can transform the mask into the armor or back again. The armor cannot be removed against the wearer’s will while they are conscious. It provides a (+3) bonus to defense or Armor Class, as appropriate to the game system, and does not impede ordinary movement, speech, or vision.

While armored, the wearer can make a melee attack with either arm-mounted weapon as a normal weapon attack. Choose bludgeoning, piercing, or slashing damage when the weapon forms. Each deals 1d8 damage, uses the wearer’s normal attack bonus, and counts as magical. The weapons do not occupy the hands.

As a bonus action, the wearer can summon or dismiss the sword and shield. The sword deals 1d8 magical slashing damage, or 1d10 when wielded in two hands. The shield grants a (+2) bonus to defense or Armor Class while held. They vanish if separated from the wearer by more than 10 feet.

As a reaction when the wearer or an ally within 10 feet is hit by an attack, the wearer can expend 1 charge to reduce the damage by 3d10. If this reduces the damage to 0, the protected creature may immediately move up to 10 feet without provoking a reaction or opportunity attack.

The wearer has advantage on checks or saving throws made to resist being frightened or knocked prone. Once per dawn, when the wearer would be reduced to 0 hit points but not killed outright, they instead drop to 1 hit point and the armor sheds bright light in a 30-foot radius for 1 minute.
