Allosaurus Fragilis

Pounce. If the allosaurus moves at least 30 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 18 Strength saving throw or be knocked prone. If the target is prone, the allosaurus can make one bite attack against it as a bonus action.

Multiattack. The Allosaurus attempts to grapple a target and then makes two attacks against that target: one with its bite and one with its claw.

Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 19 (2d12 + 6) piercing damage.

Claw. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 15 (2d8 + 6) slashing damage.

Kick. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 17 (2d10 + 6) bludgeoning damage.

Brutal Grapple. While the allosaurus has grappled a large or smaller target it can make a kick attack against it as a bonus action
