Boris

Rampaging Charge. If Boris moves at least 40 feet straight toward a target and then hits it with a tusk attack on the same turn, the target takes an extra (2d6) slashing damage. If the target is a creature, it must succeed on a DC 15 Strength saving throw or be knocked prone.

Crazed Endurance (Recharges after a Short or Long Rest). If Boris takes 15 damage or less that would reduce it to 0 hit points, it is reduced to 15 hit point instead.

Going HAM. Once a day Boris can make three attacks on the same target and if the target is already dead by the first attack Boris can attack the next closest enemy

Masterful Pack Tactics. Whenever Boris is within 5ft of ally and they are not incapacitated or unconscious he gets plus 5 and advantage on his attacks 

Tusk. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (6d6 + 5) slashing damage.

Ram. Melee weapon attack. 5ft range. 1d20+10 to hit. 7d8+5 bludgeoning damage. After using this attack Boris takes half of the damage he deals.

Tusk Parry. As a reaction Boris adds 2 to his AC until his next turn.
