Ordeal of Iron

Ordeals of Iron: The survival rate was 0% and is run by Ohm. Ohm uses his sword to try to slash someone's heart. If it hits, the person will instantly die. In addition, he rigs his territory with Milky Dials full of iron cloud linked to pressure plates on the ground. If his victim accidentally steps on one of these plates, the dials shoot the iron cloud out in the form of barbed wire, shredding them.

This was the last ordeal in Skypiea arc and only Chopper and later Zoro was involved in the game.

This ordeal has a White-Barbed Iron Deathmatch, a dome of iron cloud strands with thorns sticking out.
