Feat: Starlight Armor
Frequency once per day
You armor yourself in the light of distant suns, shielding yourself from harm. The armor grants you resistance 7 to piercing, bludgeoning, and slashing damage. The armor also sheds bright light for 20 feet (and dim light for the next 20 feet).
Whenever an adjacent creature attacks you, the attacker must attempt a Will save against your spell DC at the end of its action. On a failure, it becomes Dazzled until the end of its next turn. Regardless of the result of the save, the attacker is temporarily immune until the end of its next turn. The dazzling effect has the light and visual traits.
When you reach 17th level, the resistance increases to 10.
