Champion league

When you defeat at least one Champion, a new Npc will appear in your world. He is the Retired champion, and you can give champion trophies to him to get to different leagues. Different leagues have different champions, and each league gets harder. Once you beat a league a new dimension would appear. Every dimension has different ores and monsters, and by using them you can make strong gear to prepare for the next league. Some champions have minions, making it harder to defeat them.
