Warg Rider Prime

Rider. The warg has a rider who has 93 (11d8+44) hitpoints and AC 16 (chain mail).  Melee attacks against him have disadvantage due to his raised position. Ranged weapons attacks against him have disadvantage due to the speed of the warg mount. If he dismounts treat him as a normal orc war chief with AC 14 (hide) and animal handling +3 as an extra skill. If the warg dies the rider takes 3 (1d6) fall damage and is treated as dismounted.

Charge. If the duo moves at least 20 feet straight toward a target and then hits it with a melee attack from the rider on the same turn, that target must succeed on a DC 14 Strength saving throw or be knocked prone. If the target is prone, the warg can make one bite attack against it as a bonus action.

Keen Hearing and Smell. The warg matriarch has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Pack Tactics. The warg matriarch has advantage on an attack roll against a creature if at least one of the wolf's allies is within 5 feet of the creature and the ally isn't incapacitated.

Rampage. When the warg matriarch reduces a creature to 0 hit points with a melee attack on its turn, the warg matriarch can take a bonus action to move up to half its speed and make a bite attack.

Multiattack. The warg makes two bite attacks or one bite attack and two rider attack.

Bite. Melee Weapon Attack: + 6 hit, reach 5 ft., one target. Hit:  16 (2d10 + 6) piercing damage. If the target is a creature, it must succeed on a DC 15 Strength saving throw or be knocked prone. 

Greataxe. Melee Weapon Attack: +6 to hit, reach 5 ft., one creature. Hit: 14 (1d12 + 4 plus 1d8) slashing damage.

Spear. Melee or Ranged Weapon Attack: +6 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 12 (1d6 + 4 plus 1d8) piercing damage, or 13 (2d8 + 4) piercing damage if used with two hands to make a melee attack.

Primal Howl (1/Day). Each beast creature of the warg matriarch’s choice that is within 30 feet of it, can hear it, and not already affected by Primal Howl gain advantage on attack rolls until the start of the warg matriarch's next turn. The warg matriarch can then make one attack as a bonus action.
