Meteor Shield

This amulet has six charges. While wearing this amulet, the wearer may use an action to cause six tiny meteors, each measuring 1 inch in diameter, to encircle them. Whilst active, the wearer can perform any of the following actions. If the action requires a save, the DC is 18.

As a bonus action, the wearer may expend one charge, sending a meteor streaking towards a target within 120 feet of them. That target must make a Dexterity saving throw or take 2d6 fire damage, or half on a successful save.

Upon taking fire damage, the wearer may use a reaction to expend one charge and cause one meteor to absorb some of the flames, gaining resistance to the triggering damage.

When targeted by a melee attack, the wearer may use a reaction to expend one charge, causing a meteor to flash brightly. The triggering attack is then rolled at disadvantage.

Expending each charge reduces the number of orbiting meteors by one. These meteors remain for one hour or until all charges are expended. The amulet regains all six charges after a long rest.
