Clockwork Gladiator

Brute. A melee weapon deals one extra die of its damage when the gladiator hits with it (included in the attack).

Shutdown. If targeted by dispel magic, the gladiator must succeed on a Constitution saving throw against the caster’s spell save DC or fall unconscious for 1 minute or until it takes any damage.

Unusual Nature. The gladiator doesn’t require air, food, drink, or sleep.

Multiattack. The gladiator makes three melee attacks or two ranged attacks.

Spear. Melee or Ranged Weapon Attack: +7 to hit, reach 5 ft. and range 20/60 ft., one target. Hit: 11 (2d6 + 4) piercing damage, or 13 (2d8 + 4) piercing damage if used with two hands to make a melee attack.

Shield Bash. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 9 (2d4 + 4) bludgeoning damage. If the target is a Medium or smaller creature, it must succeed on a DC 15 Strength saving throw or be knocked prone.

Parry. The gladiator adds 3 to its AC against one melee attack that would hit it. To do so, the gladiator must see the attacker and be wielding a melee weapon.
