Reimian Empire

It just wouldn't be right to nerf blades that are forged thousands of times.

So, the method of steel processing in Japan was more of a necessity than some incredibly cool forging style. Later, they didn't abandon it because of forging traditions. It has its own advantages and disadvantages compared to the "Western" style. Japanese swords are sharper, but also more brittle. A blow to a hard object, for example, is more likely to bend a katana than a "normal" sword.

Instead of nerfing, it would be better to bring the others up to its level.

Even the Araidons?
