A season pass is an additional piece of content that is either included as part of a game version or purchased separately. Some premium and ultimate items are only at Season Pass. Three steps to activate Season Pass:
EXP: First, using EXP to open the page in Season Pass, you can gain EXP after winning the battle.
R-bucks: After opening the page by EXP, R-bucks will be used as a ticket that you need to have to enter the gate of the Season Pass. R-buck can be received by purchasing in-game
Season points: Season Points are a currency to purchase items in Season Pass. You can earn season points when finishing the battle, completing your daily quest, or enjoying special events.
