There are several different ways to beat the Sumo Wrestler.
* '''Natural''' - Simply raise your Arm Strength , Agility, Dexterity, and Endurance to a point that he no longer presents a challenge
* '''Polymorph''' - [[Polymorph]] yourself into a more powerful creature
* '''Trap''' - Place a bear trap or mine in front of the sumo's house, and lay some bananas behind it to tempt him. He will come over to eat the bananas, and probably get wounded or even dismembered from your trap. Just make sure that you don't kill him on accident and that you place the trap outside of his house not in it.
