The nobility domain is the purview of deities who charge their followers to elevate, select, test and protect the leadership of towns and kingdoms. The gods’ faithful are often found in the courts and royal houses devoted to leaders who dwell there. These gods believe that strong leadership and community unity behind that leader is essential. They usually create celebrations around coronations and dates important to the ruling families.
When you choose this domain at 1st level, you gain proficiency with heavy armor.
Starting at 1st level, you gain the ability to hinder attacks intended for others. When a creature attacks a target other than you that is within 5 feet of you, you can use your reaction to impose disadvantage on the attack roll. To do so, you must be able to see both the attacker and the target. You interpose an arm, a shield, or some other part of yourself to try to throw the attack off target.
Starting at 2nd level, you can use your Channel Divinity to strike with supernatural accuracy. When you make an attack roll, you can use your Channel Divinity to gain a +10 bonus to the roll. You make this choice after you see the roll, but before the DM says whether the attack hits or misses.
Starting at 6th level, when you or a creature within 30 feet of you takes acid, cold, fire, lightning, or thunder damage, you can use your reaction to grant resistance to the creature against that instance of the damage.
At 8th level, you gain the ability to infuse your weapon strikes with divine energy. Once on each of your turns when you hit a creature with a weapon attack, you can cause the attack to deal an extra 1d8 cold, fire, or lightning damage (your choice) to the target. When you reach 14th level, the extra damage increases to 2d8.
At 17th level, you gain resistance to bludgeoning, piercing, and slashing damage from nonmagical weapons.
