Players can earn more than 2500 ranking points – they earn trophies by winning duels.
Winning duels lets players gain more trophies. It’s important to note that every 2 weeks all players who have more than 2500 points will have their points set back to 2500. Any surplus points above that amount will be divided by 2 and the result added to their Legendary Trophies Points.

For example, let’s suppose a player finishes a season with 2600 points. In this case he will receive 50 Legendary Trophies points, due to the surplus 100 points being divided by 2, which equals 50.
Your current Legendary Trophies Points can be viewed on your Profile.
There are currently no special rewards for gaining Legendary Trophies.
