Gunnery Expertise.  Barrekk's Rifled doesn't require reloading.

Superior Critical. Barrekk's weapon attacks score a critical hit on a roll of 18–20.

Sharpshooter. Attacking at long range doesn't impose disadvantage on Barrekk's ranged weapon attack rolls. His ranged weapon attacks ignore half cover and three-quarters cover. Before he makes an attack with a ranged weapon that he is proficient with, he can choose to take a -5 penalty to the attack roll. If the attack hits, you add +10 to the attack's damage.

Sneak Attack (1/Turn): Barrekk deals an extra 14 (4d6) damage when he hits a target with a weapon attack and has advantage on the attack roll, or when the target is within 5 feet of an ally of him that isn't incapacitated and he doesn't have disadvantage on the attack roll.

Divine Precision (Recharge 5-6): Barrekk channels divine energy into its next Holy Jezail attack. On a hit, the target takes an additional 14 (4d6) radiant damage and must succeed on a DC 14 Wisdom saving throw or be frightened of him until the end of his next turn.

Thundering Horizon (3/Day): Barrekk imbues its Holy Jezail with magical energy, causing his next shot to crackle with thunderous force. When the hunter hits with its musket attack, the target takes an additional 12 (2d10) thunder damage, and all creatures within 10 feet of the target must make a DC 14 Dexterity saving throw, taking 12 (2d10) thunder damage on a failed save, or half as much damage on a successful one.

Hunter's Mark: As a bonus action, Barrekk can choose a creature it can see within 90 feet and mystically mark it as its quarry. He deals an extra 1d6 damage to the target whenever he hits it with a weapon attack, and he has advantage on any Wisdom (Perception) or Wisdom (Survival) checks it makes to find it.
