Low-Light Vision

The monster can see in dim light as though it were bright light, so it ignores the Concealed condition due to dim light.


Scent involves sensing creatures or objects by smell, and is usually a vague sense. The range is listed in the ability, and it functions only if the creature or object being detected emits an aroma (for instance, incorporeal creatures usually do not exude an aroma).

If a creature emits a heavy aroma or is upwind, the GM can double or even triple the range of scent abilities used to detect that creature, and the GM can reduce the range if a creature is downwind.

Clobbering Charge Two Actions

The pachycephalosaurus Strides up to its Speed. If it ends its movement within melee reach of a target, it can make a skull Strike against that target. If the pachycephalosaurus critically hits with this Strike, the creature hit is Stunned 1.

Sudden Shove Reaction (attack)

Trigger The pachycephalosaurus damages a Medium or smaller foe with its skull Strike

Effect The pachycephalosaurus digs in and flings its head up, shoving its foe away. It attempts an Athletics check against the target's Fortitude DC.

Critical Success The pachycephalosaurus pushes the opponent up to 10 feet away from itself and knocks the target Prone.

Success The pachycephalosaurus pushes the opponent back 5 feet.

Failure The pachycephalosaurus fails to push the opponent.

Critical Failure As failure, but the failed attempt leaves the pachycephalosaurus Flat-Footed for 1 round.

Pachycephalosauruses are normally peaceful herbivorous dinosaurs, but they grow much more violent during their mating season, when they fight one another to win over mates and warn away interlopers. They also defend themselves vehemently when potential predators stray too close to their herd. The pachycephalosaurus's skull has a distinctive dome-shaped crown surrounded by numerous blunt, bony horns. This feature, combined with the dinosaur's powerful, compact neck, allows it to make battering-ram-like charges capable of inflicting great damage.

Some humanoid groups have successfully trained pachycephalosauruses for use as mounts, but the creatures aren't particularly well suited to the task.

Pachycephalosauruses grow to a length of 15 feet and weigh 1,400 pounds.
