Special Traits

  • Grasslands Camouflage. The compsognathus has advantage on Dexterity (Stealth) checks made to hide in tall grass.
  • Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a Tiny compsognathus. The swarm can’t regain hp or gain temporary hp.


  • Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) piercing damage.


The curious bipedal lizard lets out a musical chirp. More chirps respond from within the nearby grass, becoming a sinister chorus.

Compsognathus readily bond with their pack mates, and a young compsognathus without a pack is often willing to serve a spellcaster as a familiar. Such compsognathus have the following trait.

Compsognathus is one of the smallest carnivorous dinosaurs. Its stature leads many to underestimate the deadly nature of a pack of these beasts.

Kobold Pets. Compsognathus are often kept by kobolds as pets. Kobolds are particularly fond of building traps that feed swarms of the dinosaurs by placing them at the bottom of a hidden pit or rigging a cage full of the creatures to drop on the heads of unsuspecting adventurers.

Little Dinosaurs, Big Appetites. Though compsognathus are small, they live in large packs. Compsognathus are not afraid of larger prey when they hunt together as a swarm and will seek out a meal worthy of the pack.

Silently Surrounds. Compsognathus are naturally stealthy thanks to their size and ability to blend in with natural terrain. They hunt in tall grass or areas of dense foliage, spreading out to surround their prey before attacking.
