SPECIAL TRAITS

  • Hold Breath. The spinosaurus can hold its breath for 1 hour.
  • Reptilian Affinity. The spinosaurus never willingly attacks a reptilian Humanoid, such as a lizardfolk or dragonborn, unless attacked first. If magically forced to attack such a creature, the spinosaurus has disadvantage on attack rolls against it. This trait doesn’t function if the spinosaurus’s rider or tamer directs it to attack.

ACTIONS

  • Multiattack. The spinosaurus makes one Bite attack and one Claw attack.
  • Bite. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 24 (3d12 + 5) piercing damage. If the target is a Medium or smaller creature, it is grappled (escape DC 15). Until this grapple ends, the target is restrained, and the spinosaurus can’t Bite another target.
  • Claw. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 15 (3d6 + 5) slashing damage.

Spinosauruses As Mounts

Spinosauruses mate each year in the winter. A male spinosaurus brings food and helps build an enormous nest of reeds, sticks, and mud. Then the male departs, leaving the female to lay and care for the eggs. Spinosaurus eggs are typically found in nests along riversides or deep in marshes. They are sometimes stolen and sold, generally to lizardfolk and sometimes to daring humans with a knack for training animals. These eggs are worth as much as 2,000 gp apiece; live young are worth twice that. Characters eager for spinosaurus mounts, however, should note that buying or domesticating such an enormous carnivore requires vast quantities of food and patience. They do not take easily to domestication.

Before it can be ridden in combat, a spinosaurus must practice bearing the weight of its trainer and passengers. They rarely master more than a handful of tricks, but they are extremely comfortable in the water and can be trained to be are aware that some of their riders may not breathe water.

An adult spinosaurus can carry up to six tons as cargo.

Riding a spinosaurus requires an exotic saddle, riding platform, or howdah.
