From January 19th until January 26th you will be able to try and play Valentine "Viper" Chase and Clyde "Dozen" Mullican even if you do not have them summoned, like Eric and Annie last week.
Keep Champions you like
Gather Summoning stones 💎 by doing daily challenges and use them to summon and keep the champion you prefer. Or you can summon any champion for Gold Crowns 👑.
Alternatively you can purchase a pack in the Gaijin Store, getting not only champions, but cool outfits, weapons and extra Golden Crowns!
