Terrorbirds are tall, broad, grounded Avians known for their brute force.
Keen sight: Avians have advantage on Perception skill checks that rely on sight.
Talons: Avians deal unarmed strikes with 1d4 slashing damage.
Ground charge: If Terrorbirds move at least 15 feet in a straight line toward a creature and hit with a melee attack, the creature must succeed on a Strength saving throw (DC = 8 + Strength modifier + proficiency bonus) or be knocked prone.
