In all game modes, players control characters called champions, chosen or assigned every match, who each have a set of unique abilities. Champions begin every match at a low level, and then gain experience over the course of the match to achieve a maximum level of 18. Gaining champion levels in matches allows players to unlock their champion's special abilities and augment them in a number of ways unique to each character. If a champion loses all their health, they are defeated but are automatically revived in their base after enough time passes. Players also begin each match with a low amount of gold, and can earn additional gold throughout the match in a variety of ways: by killing non-player characters known as minions and monsters; by killing or helping to kill enemy players; by destroying enemy structures; passively over time; and through unique item interactions or champion abilities. This gold can then be spent throughout the match to buy in-game items that further augment each champion's abilities and gameplay in a variety of ways. Champion experience, gold earned, and items bought are specific to each match and do not carry over to subsequent matches. Thus, all players begin each match on a more-or-less equal footing relative to their opposing team.
