Circle of the Saurian

Subclass of: Druid

The Circle of the Saurian represents a unique path for Druids who forsake civilization to embrace the majesty of the dinosaur world. These Druids dedicate themselves to understanding and protecting the most primeval creatures, forming deep bonds with dinosaurs and becoming their guardians. Their lives are spent wandering through untamed landscapes—jungles, deserts, and mountains—where they commune with these titanic beings, learning their ways and advocating for their preservation. While outsiders may view them as savage for their primal companions and lifestyles, those who understand the depth of their commitment see them as the epitome of loyalty. Through their Circle Spells, they gain powers reflecting their connection to the natural world and their dinosaur companions, from communicating with animals to summoning the forces of nature itself. The core of their circle is being able to bond to a dinosaur, transforming it into a powerful ally on their journey. This bond goes beyond mere companionship, allowing for shared abilities, senses, and even forms, making the Circle of the Saurian Druids unparalleled masters of prehistoric might and ancient wisdom. 

Druids of the Circle of the Saurian are those who have turned from the ways of civilization and instead made it their goal to protect and understand the most ancient of creatures. These druids are known for going years without speaking to another humanoid; instead trekking through jungles, deserts, and mountains while bonding with dinosaurs as they go. While some consider the druids of this circle to be the most savage of all, those who truly get to know them would instead describe them with one word: loyal.

At 3rd, 5th, 7th, and 9th level you gain access to the spells listed for that level in the Circle of the Saurian Spells table. Once you gain access to one of these spells, you always have it prepared, and it doesn’t count against the number of spells you can prepare each day.

Saurian Companion

2nd-level Circle of the Saurian feature

When you choose this circle at 2nd level, you form a bond with a dinosaur and it becomes your saurian companion.

Choose a dinosaur from the following: centrosaurus, dromaeosaurus, or pterodactyl.

Add your proficiency bonus to the companion’s AC, attack rolls, and damage rolls, as well as to any saving throws and skills it is proficient in. Its hit point maximum equals its normal maximum or four times your druid level, whichever is higher. Like any creature, the companion can spend Hit Dice during a short rest. Your druidic circle also causes the companion to gain the benefits listed on the Saurian Companion table below while the dinosaur is bonded to you. Otherwise, it is a normal dinosaur.

The saurian companion takes its turn on your initiative, and obeys any verbal commands that you issue to it. You can issue a command as a bonus action. If you don't issue any commands to the companion, it defends itself from hostile creatures but otherwise takes no actions.

If you are incapacitated or absent, the saurian companion acts on its own, focusing on protecting you and itself. The companion never requires your command to use its reaction, such as when making an opportunity attack.

You can end the bond between your saurian companion and yourself as an action, releasing it back into the wild. In the event a saurian companion dies, you must succeed on a Wisdom saving throw or gain 3 levels of exhaustion. The DC for this saving throw is 8 + your druid level + your poficiency bonus. When you are without a saurian companion, you can spend 8 hours meditating over another dinosaur, as your spirits link together and form a new bond.


Centrosauri are large, quadrupedal dinosaurs that are often mistaken for the triceratops. They have the similar double horns on their nasal bridge, but differ from the triceratops in that they have a row of small spiked horns running along the length of their frill, instead of the double horns on their foreheads. A centrosaurus grows to between 9 and 10 ft in length, and weighs upwards of 400 pounds.

Easily Tamed. Centrosauri are a favored beast of burden in many tropical regions where they are used from everything from plowing fields to pulling carts filled with produce or passengers. Most centrosauri are easily domesticated if raised in captivity and even wild centrosauri are said to be susceptible to domestication with the proper training. Some centrosaurs also serve as beasts of war, charging into battle with a rider guiding it into the fray. When trained for war centrosauri are terryfing to behold and usually suffer from intense aggression if ever removed from battle and used for more domestic purposes.

Special Ability:



Dromaeosauri are small, bipedal dinosaurs akin to the velociraptor. Dromaeosauri are noticeably heftier and sturdier built, with long tapering tails that help them counterbalance themselves when they race along to catch prey. They are known for their hunting tactics, in which they give chase to wear down their prey before pouncing and tearing them apart with their razor-sharp talons and teeth. Fully grown dromaeosauri reach lengths of 4 ft. and weigh upwards to 40 pounds.

Scouts. Many domesticated dromaeosauroi are used as scouts or hunters, using their speed and survival skills to easily track prey and elude danger. While difficult to train a dromaeosaurus makes an excellent companion for those that wander wild regions. Tamed dromaeosauri frequently corral prey for their masters, much like a classic hound dog, chasing down animals for the benefit of their masters.

Skittish. Dromaeosauri are naturally skittish unless accompanied by a large number of other dromaeosauri or other allies and tend to flee battle if the tides turn even slightly against them. Because they are so cowardly they are better equipped for stalking smaller prey and it is rare that a dromaeosaurus will attempt to attack anything larger than a Tiny creature without the company of many other allies.

Special Ability:



Pterodactyls are winged dinosaurs commonly found in mountainous regions or near the sea where they can easily swoop down and snatch prey. While grounded, they are easily targeted as prey themselves, so most pterodactyls will remain in flight whenever possible, perching high off the ground when they must land. Full grown pterodactyls reach lengths of 5 feet with wingspans of 10 feet, and weigh around 50 lbs. Their beaks are lined with tiny teeth, and are excellent for impaling prey.

Nesters. Pterodactyls are well known for making nests on the sides of cliffs or gorges safe from predators far off the ground. These locations are often close to shorelines or sources of water where the pterodactlys can easily swoop down and snatch fish or other prey from the water before returning to their nests. These nesting sites are usually populated by dozens of pterodactyls raising their young, and prime nesting spots are frequently fought over during nesting seasons.
