Bodyguard

Vigilant. The bodyguard can't be surprised.

Ward. The bodyguard is dedicated to the protection of another creature, called its ward. As long as the bodyguard is within 5 ft. of its ward and is not Incapacitated, attacks against the ward have disadvantage, and the ward has advantage on Dexterity saving throws. Moreover, instead of rolling initiative, the bodyguard can choose to act immediately after their ward in initiative order.

The bodyguard can spend 1 minute committing itself to the protection of a new ward, at which point the former ward's protection ends.

Multiattack. The bodyguard makes three Morningstar attacks. It can replace one of those attacks with Shield Bash.

Morningstar. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 22 (4d8+4) piercing damage.

Shield Bash. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 11 (2d10) bludgeoning damage. If the target is a Medium or Smaller creature, it must succeed on a DC 17 Strength saving throw or be knocked Prone.

Tireless Protector. When a creature within 5 ft. of the bodyguard is hit by an attack or makes a saving throw against a spell with no other targets, the bodyguard interposes itself. If the creature was hit by an attack, the attack hits the bodyguard instead. If the creature was the target of a spell, the bodyguard magically switches the target of the spell to itself, and automatically fails its first saving throw against the spell. 

If the bodyguard uses this ability to protect its ward, the bodyguard's reaction is not consumed.
