1. Only the challenger gains experience points from matches in Diablo.
2. The entire system is changed: Rather a single champion, there is a ranking system, not unlike Ballista. Simply it works as follows:
Ten slots of Rank 40
Ten slots of Rank 30
Five slots of Rank 20
Then 15-1.
3. When a ranked character registers at Diablo, he will face the opponent ranked above him. At ranks 40, 30, and 20 this can be a random pick out of a group of 5 or 10.
4. When an unranked character registers at Diablo, he will randomly face one of the Rank 40 combatants.
5. The stats of a ranked monster will be adjusted based on when the player trades his Official Reflector(either to fight or to upgrade stats). A player will be required to do this once a real-life week or their monster will be removed from the rankings.
6. After 150 wins, a champion is forcefully retired.
7. Players ranked 1 to 5 get special benefits, such as being able to make HNM-type monsters/skins(Behemoth, Wyrm, Suzaku, Hippogryph, etc).
