BoarFolk Warier

Charge. If the boar moves at least 20 feet straight toward a target and then hits it with a Hammer swing attack on the same turn, the target takes an extra (3d6) Bludgeoning damage. If the target is a creature, it must succeed on a DC 11 Strength saving throw or be knocked prone.

Relentless (Recharges after a Short or Long Rest). If the boar takes 12 damage or less that would reduce it to 0 hit points, it is reduced to 1 hit point instead.

Hammer swing. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4 (1d6 + 1) Bludgeoning damage.

Shout: the BoarFolk Warier squeals and shouts for its fellows, this bonus action only works if the boar is below 6 HP, if it rolls a 10 or above on a 1d20 roll it will succeed in calling on its fellows if it is above 6 HP the call of another warier is replaced with the BoarFolk Warier being healed 1d6 of HP  

Rigid and anger motivated.
