Each time a minion or champion is killed, all nearby champions gain Experience Points. When enough experience points are gained, the champion levels up and its stats are increased. The most significant way to increase stats, however, is by purchasing equipment at the shop with gold earned by killing minions, champions, or towers. A champion can only carry six at a time though, so it is important to choose the correct items.
Champions also unlock and level up skills when they level. To level up a skill, click on the button above the icon of the desired skill, near the bottom of the screen.
