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

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

Pounce. If Amaguq 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 21 Strength saving throw or be knocked prone.

Surprise Attack. If Amaguq surprises a creature and hits it with an attack during the first round of combat, the target takes an extra 14 (4d6) damage from the attack.
