With [Water Lord] Leon finally defeated, the next form should be [Wind Lord] Leon. This fight was actually favourable to him: if he did not remember it wrong, Wind element was weak against Ice. Don't ask him why since he did not know. He remembered this because he was salty about it.
You see, the fight against [Wind Lord] Leon happened at the sun was setting, so Linri still had his fire element at the time and, as it was not twilight, he couldn't use ice yet, but the next fights against [Earth Lord] Leon and twin bosses happened at night so Linri was using ice at the time.
The worst part is [Earth Lord] Leon was weak against fire. It was like admins were mocking him. In both of those fights, he was this close to having an advantage, but he couldn't. Maybe admins did that just to spite him since he one-shotted [Fire Lord] Leon.
