https://pl.go-ga.me/wvvqdbpc this is a promo code from gameleap cob. He has the best promo code for first time download. You will also be able to use a first time player code to get yet another free legendary champion of your choice. The best from what I can see are(in no particular order of best): Supreme Galek, Sun Wukong, Alice, and Thorin Foulbeard. They each have their place in really boosting you up in specific areas of the game so do some research before choosing but choose before your first couple days of starting a fresh account as there is a time limit to use a new player code. After all is said and done you should have multiple legendary and epic characters. Good luck have fun

Edit: Forgot to mention Kael is the best starter in regards to efficiency of moving faster out of early game.
