Monks of the Way of the Sumotori reject the traditional martial artist's focus on speed and dexterity in favour of size and strength. These imposing warriors maintain a strict diet and training regime that allows them to grow immensely large and strong. Their strikes carry with them immense weight and power, and yet they do not close their fists. They possess the strength to wield virtually any weapon, and yet choose to fight using only their immense bodyweight and technical knowledge of grapples and throws. Their path is one of principle, honor and unwavering dedication. The Sumotori way is steeped in tradition and spirituality -their rituals include the stomping of feet to drive away demons and evil spirits, the clapping of hands to summon the gods to witness their power, the spreading of salt over the arena and the consumption of sacred water to purify both the battleground and their own bodies of darkness and impurity. It is said that the art of Sumo was first born from the gods themselves, and the Sumotori seek to honor these gods through their devotion to righteous and glorious combat.

OPTIONAL RULES The nature of the Sumotori warriors is that of respect, honor and inner strength. As such, especially lawful Sumotori will likely adhere to the following rules, while those that have tailored their martial art for war may leave these specific values behind. Weapons. Part of a sumo's combat ritual is a raised-arm display to signify to their opponent that they are fighting without weapons. As such, Way of the Sumotori monks may reject the use of weapons completely. Unarmed Strikes. In addition, the use of closed-fist punches are outlawed in Sumo, and a monk that follows the honorable principles of the martial art may exclusively use open palm slaps and jabs for their unarmed strikes.
