This is a very modest update of the 5e Onocentaur I've posted before, bringing it in line with the post-Tasha's world. It may be old hat already, what with the D&D One playtest.
Onocentaurs have the torso, arms, and head of a human, and the legs and body of a donkey. Shaggy donkey ears grow from their head, and buck teeth are common.
They are smaller than their wild cousins, the noble centaurs, and more adapted to life among humans. They fit more easily into human-scaled buildings, and are much better climbers—Onocentaurs have an easy time navigating stairs and can even learn to climb ladders.
They are rustic creatures, often living on the rural outskirts of civilization, making their living close to the land, as farmers, herders, and artisans. They do not have a distinct culture of their own, adopting the customs and modes of the region.
Onocentaurs are often figures of ridicule. They are considered obstinate, dull, and unintentionally comical. An onocentaur might counter that they are steady, independent, and uninterested in the pretensions and fripperies that distract others.
Onocentaurs prefer short, simple given names, paired with an occupational name.
