A relative of the triceratops, the pentaceratops has two additional “horns”, which are actually just its cheekbones. Its name means “five-horned face”. Although it is herbivorous, the pentaceratops becomes aggressive when threatened.

A pentaceratops has a body about 27 feet long and weighs about 13,000 pounds.

A pentaceratops attempts to frighten away would-be predators with its mere presence and the eyelike patterns that form on its frills. If still harassed, it simply tramples smaller creatures and lashes out with its larger horns against bigger threats.

Frightful Presence (Ex): A pentaceratops can inspire terror by charging or attacking. Creatures within a radius of 30 feet are subject to the effect if they have fewer HD than the pentaceratops. A potentially affected creature that succeeds on a DC 14 Will save remains immune to that pentaceratops’s frightful presence for 24 hours. On a failure, creatures with 4 or less HD become panicked for 4d6 rounds and those with 5 or more HD become shaken for 4d6 rounds. Pentaceratops ignore the frightful presence of other pentaceratops. Frightful presence is a mind-affecting fear effect. The save DC is Charisma-based.

Trample (Ex): Reflex half DC 24. The save DC is Strength-based.

Skills: A pentaceratops has a +8 racial bonus on Intimidate checks due to the eyelike patterns on its frill.
