Classes are broken down into weight classes like this:
| Class | Max Lv | Total Min Lv | Total Max Lv |
|---|---|---|---|
| Super Light | 1 | 1 | 1 |
| Light | 10 | 25 | 30 |
| Welter | 30 | 90 | 100 |
| Middle | 50 | 160 | 180 |
| Heavy | 70 | 200 | 250 |
| Open | 100 | 400 | 500 |
The way to read this is that there are 6 Classes. Each class has a Maximum Level that a PET can be on a certain class team, a Total Minimum Level that the WHOLE TEAM can be, and a Total Maximum Level that the WHOLE TEAM can be.
Example:
Let’s say I want to make a Welter weight team. Well, if I want to make a Welter weight team then no member of my team can be over level 30. In addition the TOTAL LEVEL of my entire team cannot be less than 90 or greater than 100.
So, here are a few samples of a Welter weight team.
Ranks are broken down into the following ranks:
Everyone starts out as a C rank duelist and then it goes up to B, A, S and SS. An Open Classed, SS Ranked duelist is considered by many to be the best duelists in the world.
To rise in rank you have to win 4 duels between other duelists of your same rank.
Example:
If I am a C rank duelist then I have to beat 4 other C rank duelists before I am promoted to the rank of B.
If I am an A rank duelist then I have to beat 4 other A rank duelists before I am promoted to the rank of SS
Now in order to duel an NPC you have to be BOTH in their same Class and Rank. So even if you are a Lightweight and go to a Lightweight NPC to duel, if you are both also not in the same rank they will deny you.
