The "Celestial Stems" represent the REN competition mode. In this mode, you will be able to win XP, koban, or accessories. You can also get your rank to reach the REN world summits.



There are several stems, each with their own rules. Procedures for their registration and classification differ from one stem to another. Furthermore, each stem will assign different rewards to its best fighters.
The XP gains in a Stem vary according to several criterias such as:
- The difference in level with the opponent,
- The score difference between the loser and the winner of a duel,
- Number of consecutive victories.
This system helps balance the XP gains according to the player's profile.
Also the rewards you get will depend on your performance in the selected Stem.

Note: You have access to all Celestial Stems from the very beginning. However, new ones will appear regularly in the REN world.

Now, select the Stem of your choice and begin the battle!
