Animated Guardian

Antimagic Susceptibility. The armor is incapacitated while in the area of an antimagic field. If targeted by dispel magic, the armor must succeed on a Constitution saving throw against the caster's spell save DC or fall unconscious for 1 minute.

False Appearance. While the armor remains motionless, it is indistinguishable from a normal suit of armor.

Multiattack. The guardian makes two attacks, only one of which can be a Maneuver.

Halberd. Melee Weapon Attack: +4 to hit, reach 10 ft., one target. Hit: 7 (1d10 + 2) slashing damage.

Maneuver: Brace. The guardian can make an attack against the next creature that enters its range without expending a reaction.

Maneuver: Cleave. The guardian makes a Halberd attack against up to three different creatures within a 10-foot cone. On a hit the attack deals half damage (rounding up) to each creature.

Maneuver: Rush. The guardian moves 10 feet in a straight line before making a Halberd attack against a creature within range. On a hit the attack deals an additional 1d6 damage and must make a DC 13 Strength saving throw or be knocked prone.

Riposte. If a creature within 10 feet of the animated guardian misses it with a melee attack, the guardian can immediately make a Halberd attack against that creature.
