Centaur

Centaurs are apparently hybrid creatures that combine human and equine features. They are between six and seven feet tall (from hoof to head), and weigh between 600 and 1000 pounds. Aside from a few exceptional specimens, centaurs are mortal beings, and have a lifespan roughly equal to that of humans.   There are several distinct varieties of centaurs, which, despite physical similarities, have little to do with one another. The largest group, known as the Ixians, are native to the lands of Chymeria, though some dwell in the northern portions of Kadmeia as well. These centaurs are descended from Ixion, a tribal chieftain, and Nephele, a cloud nymph who assumed the form of Hera at Zeus' prompting. Ixion, who lusted after Hera, fell for Zeus' trap, and was punished, but not before Nephele became pregnant with Kentauros. As lustful as his father, Kentauros sired offspring from a herd of wild mares, and these became the first centaurs. Since then, they continue to live and travel in bands, and to exhibit the same behavior as their forbears. They are prone to pillage and internecine warfare, and but are particularly susceptible to the effects of wine. As Ixians are able to reproduce, there are apparently centaurides - female centaurs - among them, though the males tend to keep their whereabouts hidden from outsiders. Some centaurides do join their male counterparts in raiding expeditions.

Ability score increase: STR +1
Age: Lifespan equivalent to that of humans
Size: Centaurs are considered Size L creatures. 

• Their weight allowance is that of a Size L creature (i.e. double the amount normally allowable by their Strength;
• They use a die one size greater than that normally stipulated by their class (e.g. a centaur fighter would have d12 hit dice as opposed to d10
• On the other hand, as a Size L creature, centaurs receive a -1 penalty to their AC;
• A centaur can be mounted by a size M creature;
• Despite their size, a centaur's torso and arms are human-sized; therefore, they may not use very heavy weapons without the standard penalty;
• Centaur-sized armor, if available, will normally cost four times the listed price;
• Mountainous terrain is doubly difficult for centaurs, and they may only move through it at 1/4 their normal movement rate;
• Centaurs make all climbing checks at Disadvantage;

Movement: 50 feet/round
Hooves: A centaur's hooves are natural melee weapons, which can be used to deliver unarmed strikes. On a successful hit, they deliver 2d4 + STR modifier bludgeoning damage.
Charge: if a centaur moves at least 30 feet straight toward a target and then hit it with a melee weapon attack on the same turn, they can immediately follow that attack with a bonus action, making one attack against the target with their hooves.
