Cathedral Guardian

Might of the Cathedral. Cathedral Guardians can Smite to deal additional (+4) damage to any Beast or Monstrosity.

Iron Will. Will never stand down from duty, and cannot be persuaded from combat once a fight has begun. The only way to peacefully end a battle with a Cathedral Guardian is to roll a perfect Intimidation check (NAT 20).

Bless Thy Weapon. The knight shrouds it's weapon in a mist of light. Grants advantage on attacks for 2 turns.

Reveal Thy Truth. One random party member will have their AC reduced by 5 for 2 turns, or until they are damaged, which will return it to normal.

Stand Down. The Cathedral Guardian lets out a groan, compelling entities nearby (Up to 30 ft.) to lay down their weapons and stop fighting. May be avoided by a successful CHA check (>14). If a creature is affected, they may be assisted by another creature so long as they are not suppressed.

Guardian's Gauntlet. Melee Weapon Attack: +2 to hit, reach 10 ft., 1 target. Hit: 5 (1d8 + 3) [Bludgeoning] damage. 

Strike. Melee Weapon Attack: +4 to hit, reach 15 ft., 1 target. Hit: 5 (1d10 + 3) [Bludgeoning] damage. 

Strength of the Communion. Cathedral Guardians gain bonus actions when they are in groups. For every additional Cathedral Guardian within 50 ft. they gain 1 bonus action.
