Moving up or down in the league system depends on your arena points at the end of a season (2 weeks).
At the end of each season, all players are ranking depending on their arena points and their new league depends on their ranking.
Try to always be first of your league and get as many points as you can to move up as fast as possible.
There are 4 different leagues:
- Master (gold medal with wings): 20 best players on the server
- Gold: all players from 21st to 100th, in 4 seperate leagues
- Silver: all players from 101th to 420th in 16 seperate leagues
- Bronze: all players from 421th to the last in an infinity of seperate leagues
The points earned or lost depend on the difference in points between the two opponents.
If a player with a lot of arena points beats a player with few points, he will earn little if not no points at all (if the difference is greater than 100 points).
If a player with few arena points beats a player with many points, we will earn a lot of points.
Therefore, points earned or lost do not depend on leagues or levels! A player in a lower league or with a lower level could have a lot more arena points than you. Furthermore, if a player with a lot less points defeats you, you will lose many points.
Try to always challenge players with higher arena points than yourself to be in a low risk, high reward situation.
