Orcs have a bad reputation for violence and some assume that half-orcs are the same. To some extent, this is true. They are swifter to react physically than humans, but this might just as well take the shape of a good sailor. Their strong build helps with this. Unfortunately, this has also given them a reputation for being better with their hands than their brains. While this isn't an inherent trait, society pushes them towards manual labour in most places.
Half-orcs have a strong build with wide shoulders. Their lower jaw grows tusks that stick out up to a couple of centimetres. The jaw tends towards square. Their hair is usually black while their skin tone leans towards grey, green, or yellow compared to their human parent.
Pregnancy is only seven months, but often quite painful. The pain is mitigated if the mother has a high amount of adrenaline. Multiple births are not uncommon and even harder on the mother.
Half-orcs have inherited their orcish parent's ability to see in the dark.
