Trolls are generally found in rather uninhabited places, and vary greatly in their physical appearance. What they do all seem to have in common is that they are quite strong, extremely hardy, and have an amazing capacity to heal damage quickly. While not too smart, not too wise, and being shunned by most races, trolls are not so bad as people might think, and can be quite a welcome addition to any group.
Trolls are protected by their leather-like skin, and can utilize their claws to inflict damage in addition to using weapons. They shun direct sunlight however, and lose their incredible capacity to heal damage when the sun is upon them.
