Unicorn tortoises are magical creatures that make their homes in deep temperate forests, caves, and the upper levels of abandoned ruins. They are about 2' tall, 3 1/2' long and weigh 180-300 pounds. They are gray in color with two narrow purple strips down the top of the shell.
Unicorn tortoises graze upon all manner of plants and fungi. They are prized as a source of food and their shell has many uses. Unicorn tortoises are surprisingly challenging prey as their magical nature gives them an unnaturally high movement rate.
COMBAT: Unicorn tortoises are not aggressive, preferring to use their speed to escape predators. If cornered or otherwise forced to defend itself, they will seek to charge their opponents where possible, using their speed and mass. While of animal intelligence, they attempt to fight as a herd, by singling out opponents for mass attacks.
CHARGE: Unicorn tortoises can charge, where time and space allow, gaining a +2 bonus to attack and damage, due to their magically-enhanced speed and agility. A bipedal opponent weighing the same or less than than the unicorn tortoise, must make a successful saving throw when struck by a charge or else they will be knocked down.
Note: This creature was originally created by James Raggi's Random Esoteric Creature Generator for Classic Fantasy Role-Playing Games and their Modern Simulacra, although it has gone through several iterations since.
