Although the fight between Nessa and Mort was agreed upon beforehand, it wasn't an 'official' match. As such, there was no referee, no rules, and no ring. It started when they were ready. It would end when one of them lost. And it would take place where their attacks took them.
Mort took a moment to size Nessa up as they slowly circled each other. It was the first time he saw that kind of armor. It looked alive. It looked like a second layer to her body. It moved with her body, and the joints were connected seamlessly. Nessa's armor had no apparent weaknesses, not even the flat shoulder socket.
However, Mort didn't need to rely on taking advantage of the structural deficiencies of his opponent's armor. He was a miner. He used a pickaxe. He mined stones, ores, and mountains. He was used to breaking things that others considered unbreakable with nothing but a swing of his pickaxe.
