This creature resembles a blackish-brown warhorse that rears, exposing six muscular legs and terrible hooves.

Kathlins are powerful, six-legged horses that spend their time roaming the temperate plains they call home. They generally avoid contact with civilized races, preferring the seclusion of their homeland above all else.

Kathlin congregate in herds and two types of herds can be encountered; bachelor or mixed. A bachelor herd consists of all males. Each male in such a herd is young and hasn’t reached full maturity yet. The second type of kathlin herd is a mixed herd that contains both females and males. In a mixed herd, there will always be at least one male for every three females (it’s part of the harem-like structure of the kathlin society).

When a bachelor male reaches maturity, it leaves the bachelor herd and seeks out a mixed herd where it selects up to three females to mate with. Should the kathlin select a female that is mated with another male, a battle ensues. The male that wins this fight claims the female as its own.

Kathlins can be trained as mounts or beasts of burden. Young are usually easier to train than older kathlins, and males make better mounts than females. They can also be trained to serve as a mount in combat. They are fearless creatures and do quite well in such situations. Trained properly, a kathlin makes an excellent combat steed. When fighting, a kathlin rears back on its hind legs and slashes with its hooves or gnashes at a foe with its bite.

Non-domesticated or untrained kathlin back away from combat if overwhelmed. They do not do so out of fear but are intelligent enough to know when they are beaten.

Training a Kathlin

A kathlin requires training before it can bear a rider in combat. To be trained, a kathlin must have a friendly attitude toward the trainer. Training a friendly kathlin requires six weeks of work and a successful DC 15 Wisdom (Animal Handling) check.

Kathlin young are worth 5,000 gp on the open market. Professional trainers charge 1,000 gp to rear or train a kathlin.

Carrying Capacity Carrying Capacity: A kathlin is unencumbered up to 300 pounds; lightly encumbered from 301 to 600 pounds; and encumbered from 601 to 900 pounds. It cannot carry more than 900 pounds, A kathlin can drag 4,500 pounds.
