  • 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 13 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.


  • Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 15 (2d10 + 4) piercing damage.
  • Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage.


While smaller than the more famous Tyrannosaurus rex, the allosaurus is a fearsome predator. It is far stealthier than its larger kin and more likely to strike in ambush from behind large trees. Allosauruses tend to travel in pairs, either mated pairs or a pair of siblings of the same sex. Territorial, allosauruses are known to track foes for miles before making their presence known in a snarling, roaring attack.
