Cerberus Guardian (Mass Effect 3)

Talon Ammo Counter. Whenever the guardian makes an M-385 Talon attack, add 1 to its Talon ammo counter. Once the counter reaches 4, the guardian cannot use its M-358 Talon until it uses a bonus action to reload.

Team Fighter. The guardian has advantage on attack rolls against a creature if at least one of the guardian's allies is within 5 feet of the creature and the ally isn’t incapacitated.

Impenetrable Defense. The guardian carries an enormous heavy shield. While wielding this shield, normal attacks from in front of the guardian have no effect, and critical hits land as regular hits. If subjected to 45 lbs. or more of force (typically from biotic abilities, powerful impacts, or environmental effects), the guardian staggers, making it susceptible to normal damage for 1d4-1 turns. The guardian immediately stops staggering on its turn. If subjected to 90 lbs. or more of force, the shield is wrenched from the guardians hands, and they take damage normally. The guardian takes damage normally if flanked or attacked from behind.

Multiattack. The guardian makes four M-358 Talon (shot) attacks.

M-358 Talon (Strike). Melee Weapon Attack: +6 to hit, reach 5 ft., 1 target. Hit: 7 (2d6) bludgeoning damage.

Shield Bash. Melee Weapon Attack: +6 to hit, reach 5 ft., 1 target. Hit: 14 (4d6) bludgeoning damage, and the target must succeed on a dc18 strength saving throw or be knocked prone.

Stun Baton. Melee Weapon Attack: +6 to hit, reach 5 ft., 1 target. Hit: 5 (2d4) bludgeoning damage and 2 (1d4) lightning damage, and the target must succeed on a dc16 constitution saving throw or be stunned until the end of their next turn.

M-358 Talon (Shot). Ranged Weapon Attack: +5 to hit, range 80/320 ft., 1 target. Hit: 9 (2d8) piercing damage, and the guardian has +1 added to its Talon ammo counter.
