Bugbear Huntmaster

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

Go for the Throat. As a bonus action, the bugbear huntmaster targets one beast within 30 feet that can see and hear the bugbear. The beast can use its reaction to move up to half its speed and make one melee attack against a creature. If the beast hits, the hit is automatically a critical hit.

Slay Foe (1/turn). The bugbear huntmaster deals an extra 9 (2d8) damage with its weapon attack if it hits a creature that doesn't have all its hit points

Summon Beast (Recharges after Short or Long Rest). The bugbear huntmaster summons 1d2 worgs. The beasts appear in unoccupied spaces within 30 feet of the bugbear and acts as its allies. The beasts act right after the bugbear on the same initiative count and fight until they're destroyed. They disappear when the bugbear dies. 

Surprise Attack. If the bugbear huntmaster surprises a creature and hits it with an attack during the first round of combat, the target takes an extra 7 (2d6) damage from the attack.

Multiattack. The bugbear huntmaster makes two melee attacks or two ranged attacks.

Greatsword. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 12 (4d6 + 3) slashing damage.

Hunting Bolas. Ranged Weapon Attack: +6 to hit, range 20/60 ft., one target. Hit: 5 (1d3+3) bludgeon damage. The target must succeed on a DC 14 Strength saving throw or be restrained and knocked prone. As an action, the restrained creature can make a DC 14 Strength check, escaping on a success. The effect ends if the hunting bolas is destroyed. The hunting bolas has AC 10, 5 hit points, resistance to bludgeoning damage, and immunity to poison and psychic damage.
