Shield of the Hidden Lord

While holding this shield, you gain a +2
bonus to AC and resistance to fire damage.
The shield has 3 charges. You can use an action to expend 1 charge to cast fireball or 2 charges to cast wall of fire from the shield (save DC 21 for each). The wall of fire spell lasts for 1 minute (no concentration required). The shield regains all expended charges daily at dawn.
