Aroura High Guard

Shield Bastion. While wielding a heavy shield, the Aurora High Guard grants half cover (+2 AC) to allies within 5 feet.

Radiant Bulwark. When the High Guard takes damage, it can reduce the damage by 15 (3d8 + 2). If the damage is reduced to 0, it emits radiant energy; creatures of its choice within 10 ft. gain 10 temporary hit points. (Recharge 5–6)

Aura of Resolve. Allies within 10 feet have advantage on saving throws against being frightened or charmed.

Guardian’s Interception. When a creature the High Guard can see attacks a target within 5 feet of it, the High Guard can use its reaction to impose disadvantage on the attack roll.

Actions

Multiattack. The Aurora High Guard makes two attacks with its greatsword or one greatsword attack and one shield bash.

Greatsword of Freedom. Melee Weapon Attack: +9 to hit, reach 5 ft., one target
Hit: 14 (2d6 + 5) slashing damage plus 9 (2d8) radiant damage.

Shield Bash. Melee Weapon Attack: +9 to hit, reach 5 ft., one target
Hit: 10 (1d8 + 5) bludgeoning damage, and the target must succeed on a DC 17 Strength saving throw or be knocked prone.

Radiant Linebreaker (Recharge 5–6). The High Guard sweeps its greatsword in a 15-foot cone of radiant force. Each creature in that area must make a DC 17 Constitution saving throw, taking 27 (6d8) radiant damage on a failed save, or half as much on a success. Creatures that fail are also pushed 10 feet away.

Shield Wall Stance. Until the start of its next turn, the High Guard gains +2 AC and creatures provoke opportunity attacks from it even if they take the Disengage action.

Unbreakable Stand (1/Day). When reduced to 0 hit points, the High Guard instead drops to 1 hit point and immediately gains 30 temporary hit points.
