Selected Brawling Weapons
History & Background (Dossier)
Creatures, or animals, are often born with a powerful set of naturally evolved weapons such as claws, horns, teeth, tails, etc. But sophonts often evolve to emphasize greater intelligence to the minimalization or exclusion of natural weapons and armor.
However, even an unarmed and unarmored sophont like a human being, still possesses a considerable number of basic weapons in the form of fists, feet, and martial arts. A melee combat involving brawling weapons can be dangerous with improvised weapons or even unarmed combat.
