High in the mountains of the mysterious isle of Krikta lies a remote monastery populated by immense grapplers known as rikishi. Rikishi practice the ancient weaponless fighting art of sumo wrestling. Sumo emphasizes use of the rikishi's considerable weight as a weapon to crush his enemies. An experienced rikishi can use his bulk to move mountains. All rikishi possess some levels of monk, but multiclass monk/fighters are often attracted to the offensive capabilities of the class. Other classes are not often found on the rikishi's path.

Weighty Blow: At 1st-level, the rikishi learns to put all of his weight behind his blows. When attacking with an unarmed strike, the rikishi adds his Constitution modifier (if positive) in addition to his Strength modifier to his melee damage rolls. This ability, making use of heavy, ponderous swings, cannot be used in conjunction with a flurry of blows.
Improved Trip: The rikishi gains Improved Trip as a bonus feat at 2nd-level. The free melee attack can be used against an overrun opponent.
Canny Wrestling: A 3rd-level rikishi no longer provokes attacks of opportunity when attempting to start a grapple.
Mighty Grappler: At 4th-level, the rikishi gains greater mastery over his considerable bulk. He gains a +4 bonus to grapple checks. At 8th-level, this bonus increases to +8.
Trample: At 5th-level, the rikishi gains the Trample ability as described in the Monster Manual.
Improved Overrun: The 6th-level rikishi is treated as one size category larger when making an overrun attempt. At 9th-level, he is considered two sizes larger.
Bear Hug: The 10th-level rikishi can make a grapple check to break his opponent's spine. The opponent is entitled to a Fortitude save, the DC being the rikishi's grapple check result. A creature failing the save is permanently paralyzed. The paralysis can only be reversed by a heal spell or stronger magic.
