Amarok

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

Shadow Camouflage. The amarok has advantage on Dexterity (Stealth) checks made in dim light or darkness.

Evasion. If the amarok is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.

Pounce. If the amarok moves at least 10 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 14 Strength saving throw or be knocked prone.

Surprise Attack. If the amarok surprises a creature and hits it with an attack during the first round of combat, the target takes an extra 7 (2d6) damage from the attack.

Multiattack. The amarok makes three attacks: one with its bite and two with its claws.

Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 3) piercing damage. If the target is a creature, it must succeed on a DC 14 Strength saving throw or be knocked prone.

Claws. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 3) slashing damage.

Evade. The amarok adds 3 to his AC against one attack that would hit it. To do so, the amarok must see the attacker.
