Aerosaur

The aerosaur has advantage on saving throws against spells and other magical effects.

The aerosaur makes one Bite attack and one Talons attack.

Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 27 (3d12 + 8) piercing damage. If the target is a Huge or smaller creature, it has the grappled condition (escape DC 18). Until this grapple ends, the target has the restrained condition, and the aerosaur can't Bite another target.

Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 24 (3d10 + 8) slashing damage.

The aerosaur beats its wings, creating bursts of thunderous force. Each creature within 10 feet of the aerosaur must make a DC 20 Strength saving throw. On a failed save, a creature takes 38 (7d10) thunder damage, is pushed up to 30 feet horizontally from the aerosaur, and has the prone condition. On a successful save, a creature takes half as much damage and is pushed up to 15 feet horizontally from the aerosaur.
