Undead Fortitude. If damage reduces the zombie to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, the zombie drops to 1 hit point instead.

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

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 4 (1d8) piercing damage + 3 necrotic damage. If the target is a humanoid, it must succeed on a DC 12 Constitution saving throw or be cursed with werewolf lycanthropy.

Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 7 (2d4 + 3) slashing damage.
