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 (Wolf or Hybrid Form Only). Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 15 (2d8 + 6) piercing damage. If the target is a humanoid, it must succeed on a DC 14 Constitution saving throw or be cursed with werewolf lycanthropy.
