Armory Golem

Armored Up. The Golem counts as though it is wearing metal armor for the purposes of various spells and effects.

Constructed Mind. When the Golem is Stunned or Paralyzed, it acts as though it is Restrained instead.

Defensive Stance. While the Golem is not within 10 ft. of a hostile creature, it can take the Dodge action as a free action.

Multiattack. The Golem makes two Deadly Weapon attacks. If both attacks hit their target, the target falls Prone.

Deadly Weapon. Melee Weapon Attack:  +10 to hit. reach 10 ft., one target. Hit: 26 (2d20 + 5) bludgeoning damage. If this attack causes a creature to drop to 0 hit points, the target immediately fails one death saving throw.

Hell Breaks Loose (Recharge 5-6). The Golem makes one Deadly Weapon attack against all creatures within 10 ft. of it. If no attacks hit, then the Golem can move up to 5 ft. and use this attack once more - if it misses all attacks the second time, it cannot use this action until it recharges.
