Traits

Herd Instinct. While within 30 feet of another friendly Camptosaurus or allied beast, the Camptosaurus has advantage on Wisdom (Perception) checks and Dexterity saving throws.

Fleet-Footed. The Camptosaurus can take the Dash action as a bonus action on its turn.

Keen Senses. The Camptosaurus has advantage on Wisdom (Perception) checks that rely on sight or smell.

---

Actions

Multiattack. It makes two attacks: one with its Kick and one with its Tail.

Kick. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 3) bludgeoning damage, and the target must succeed on a DC 13 Strength saving throw or be knocked prone.

Tail. Melee Weapon Attack: +5 to hit, reach 10 ft., one target. Hit: 11 (2d6 + 3) bludgeoning damage.

Stampede (Recharge 5–6). The Camptosaurus charges up to 30 feet in a straight line. Each creature in its path must make a DC 13 Strength saving throw, taking 14 (4d6) bludgeoning damage on a failed save, or half as much damage on a success. A creature that fails its save is also knocked prone.

---

Reactions

Tail Sweep. When a creature the Camptosaurus can see moves into its reach, it makes one Tail attack against that creature.

---

Legendary Actions

The Camptosaurus can take 2 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature’s turn. The Camptosaurus regains spent legendary actions at the start of its turn.

• Quick Step. The Camptosaurus moves up to 20 feet without provoking opportunity attacks.
• Defensive Posture. The Camptosaurus braces itself, gaining +2 AC until the start of its next turn.
• Warning Call (Costs 2 Actions). The Camptosaurus emits a resonant bark. Each allied beast within 30 feet that can hear it gains advantage on the next attack roll or saving throw before the start of the Camptosaurus’s next turn.

Tactics

Camptosaurus avoids confrontation whenever possible, relying on its agility and herd coordination to escape predators. When forced into battle, it begins with Stampede to scatter attackers, then uses Quick Step to reposition while delivering swift Tail Sweeps. Herds coordinate through warning calls, forming defensive circles around their young—unyielding walls of muscle, speed, and instinct.

Exceptionally dumb and slow, this is easy prey for any hungry predator, typically too stupid to run until one of its herd number is killed

Camptosaurs are particularly stupid and skittish herbivorous dinosaurs. A camptosaurus is usually around 20 feet long, with about a third of that being tail. They are brightly colored, with stripes and wattles being used by the males to attract mates. This, combined with their dull minds, might have led them to extinction if not for two things-they are quite fast, and their sense of smell is incredibly acute. They have been known to live in herds amongst brachiosaurs or camarasaurs: the sauropod’s long necks and keen eyes and the camptosaur’s sensitive noses compliment one another and keep the herds aware of most dangers.

COMBAT

Camptosaurs always flee from combat, but they will lash out with their tails if cornered or knocked down.

*A camptosaurus’s tail slap is treated as a secondary attack and adds only half the camptosaurus’s Strength bonus to the damage roll.

Keen Scent (Ex): A camptosaurus can detect creature through scent up to 60 feet away.

Stampede (Ex): A frightened herd of camptosaurs flees as a group from a perceived danger, literally running over creatures in their path. Large or smaller creatures caught in a camptosaur stampede take 1d12 points of damage for every five camptosaurs in the herd (Reflex DC 14 halves). The save DC is Strength-based.

SPECIAL ABILITIES

Fleet-Footed (Ex)
A Camptosaurus can take the run action through difficult terrain at only half penalty. When it charges or runs, its base speed increases by 10 feet.

Herd Instinct (Ex)
While within 30 feet of another Camptosaurus, it gains a +2 morale bonus on Reflex saves and Perception checks.

Reactive Step (Ex)
Once per round, when a creature moves adjacent to the Camptosaurus, it may take a 5-foot step without provoking attacks of opportunity, even if it has already taken one this round.

Stampede (Ex)
When three or more Camptosauruses charge in the same round, they can move through the same squares. Any creature in their path must succeed at a DC 15 Reflex save or take 3d6 bludgeoning damage and be knocked prone. The save DC is Strength-based.

TACTICS

Before Combat
Their herds are vigilant and skittish, using their scent and sight to detect predators at great distances. They attempt to flee long before danger reaches them.

During Combat
If trapped, a Camptosaurus kicks at attackers, then pivots with a tail slap before retreating. Herds coordinate to trample and overrun threats using their stampede ability.

Morale
If reduced to half its hit points or separated from its herd, a Camptosaurus flees at full speed, using fleet-footed to escape.

DESCRIPTION

Swift, muscular herbivores roughly 20 feet long and over a ton in weight. They travel in tight herds across fern-covered floodplains and forest edges, grazing on cycads and low vegetation. Though nonaggressive, they react to predators with startling unity—stomping, kicking, and stampeding in thunderous waves of survival instinct. Their mottled brown-green hides help them blend with Jurassic foliage, while their wary eyes and sharp hearing ensure few creatures catch them unprepared.
