(Dinosaur) Sinornithosaurus

Sinornithosaurus is a small, agile dinosaur belonging to the Dromaeosaurid family. With a length of approximately 3 to 4 feet, it possesses a sleek and streamlined form, covered in feathers of varying colors, providing excellent camouflage within its forested habitat.

Its keen sense of smell allows Sinornithosaurus to detect potential prey from a distance, making it a proficient hunter. With sharp claws and a powerful jaw, it delivers swift and precise attacks, often using its speed to outmaneuver larger foes.

Despite its limited intelligence, Sinornithosaurus displays remarkable coordination within its pack, effectively utilizing pack tactics to bring down larger creatures. While it primarily relies on instinct, it can demonstrate cunning and resourcefulness in securing food and evading danger.

Found in the shadowy recesses of dense woodlands, Sinornithosaurus moves effortlessly through trees, using its climbing ability to its advantage. Although not inherently aggressive, it will defend itself fiercely when threatened.

    Keen Smell. Sinornithosaurus has an acute sense of smell, granting it advantage on Perception checks related to scent.

    Pounce. When Sinornithosaurus moves at least 20 feet in a straight line towards a creature and hits it with a claw attack on the same turn, the target must succeed on a DC 12 Strength saving throw or be knocked prone. If the target is prone, Sinornithosaurus can make one bonus bite attack against it.


    Multiattack. Sinornithosaurus can make three attacks: one bite and two claws.

    • Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 3) piercing damage.
    • Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d4 + 3) slashing damage.
    • Talon Rake (Recharge 5-6). Sinornithosaurus makes two claw attacks against one target. If both attacks hit, the target is grappled (escape DC 13). While grappled, the target is restrained and takes 5 (1d4 + 3) slashing damage at the start of each of its turns. Sinornithosaurus cannot use this attack while grappling a creature.


    Evasive Maneuver. When Sinornithosaurus is hit by an attack, it can use its reaction to halve the damage received from the attack.
