Battle Formation. The Roayl Guard has been trained to fight in groups of three. If they are grouped up like this, they can move simultaneously and do so on the turn of the member that is highest in the initiative order. While grouped up, they gain a +2 bonus to their AC, their movement is halved and they can not use the Dash or Disengage action.

Naginata. Melee Weapon Attack: +5 to hit, reach 10 ft., 1 target. Hit: 8 (1d10 + 3) slashing damage. 

Naginata (Pole End). Melee Weapon Attack: +5 to hit, reach 10 ft., 1 target. Hit: 5 (1d4 + 3) bludgeoning damage. 

Nodachi. Melee Weapon Attack: +5 to hit, range 5 ft., 1 target. Hit: 10 (2d6 + 3) slashing damage.

Pole Attack. After making an attack with its Naginata, the Royal Guard can immediately make a Naginata (Pole End) attack as a bonus action.

Interception. When a creature the Royal Guard can see hits a target, other than it, within 5 feet of it with an attack, it can use its reaction to reduce the damage the target takes by 1d10 + 2 (to a minimum of 0 damage). The Royal Guard must be wielding a shield or a simple or martial weapon to use this reaction.
