Allosaurus

The classic great hunter of its age, wielding a gaping jaw like a serrated hatchet that it swings down into prey and tears free. It hunts alone or in loose, squabbling packs. It rules woodland and floodplain across a wide territory, scavenging as readily as it kills, and it will worry a great herbivore for days on end - opening wound after wound until the giant simply falls.

Hatchet Bite: slashing, melee 10 ft, +2 to hit, 2d10+4 slashing. Claws: slashing, melee 5 ft, 1d8+4 slashing. Ripping Bite: against a wounded or prone target the bite deals an extra 2d6, cooldown 2 rounds.

Pack Hunter: +2 to hit a target already engaged by another large predator. Keen Smell: tracks blood for miles. Senses: Night Vision (60 ft).
