Two teams of five players compete to destroy the opposing team's "Nexus", which is guarded by the enemy champions and defensive structures known as "turrets". Each team's Nexus is located in their base, where players start the game or reappear after death. Non-player characters known as minions are generated from each team's Nexus and advance towards the enemy base along three lanes guarded by turrets: top, middle, and bottom. Each team's base contains three "inhibitors", one behind the third tower from the center of each lane. Destroying one of the enemy team's inhibitors causes stronger allied minions to spawn in that lane, and allows the attacking team to damage the enemy Nexus and the two turrets guarding it. The regions in between the lanes are collectively known as the "jungle", which is inhabited by "monsters" that, like minions, respawn at regular intervals. Like minions, monsters provide gold and XP when killed. Another, more powerful class of monster resides within the river that separates each team's jungle. These monsters require multiple players to defeat and grant special abilities to their slayers' team. For example, teams can gain a powerful allied unit after killing the Rift Herald, permanent strength boosts by killing dragons, and stronger, more durable minions by killing Baron Nashor.
