Avabruck Pack-Keeper

Shapechanger. The werewolf can use its action to polymorph into a wolf-humanoid hybrid, or back into its true form, which is humanoid. Its statistics, other than its AC, are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies. This change does not occur at-will. They remain in humanoid form most of the time, only reverting to hybrid form during the full moon.

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

Pack Leader. The werewolf has trained a pack of wolves or large dogs that follow the werewolf wherever it goes. A pack leader will have 6 (2D4+1) wolves or dogs with it at any time. (Use the Dire Wolf stats for these.)

Multiattack. (Humanoid or Hybrid Form Only). The werewolf makes two attacks: two with its spear (humanoid form) or one with its bite and one with its claws (hybrid form).

Bite (Hybrid Form Only). Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) piercing damage. If the target is a humanoid, it must succeed on a DC 12 Constitution saving throw or be cursed with werewolf lycanthropy.

Claws. (Hybrid Form Only). Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 8 (2d4 + 3) slashing damage.
