ARAM

ARAM, the acronym for All Random All Mid, is a supported PvP game mode in League of Legends. Upon entering champion select, ten summoners, five on each team, randomly summon a champion from their available pool of champions (owned and free play). They are allowed to "reroll" their champion, based upon reroll points (a maximum of 2 rerolls can be saved up at once), which are gained by both playing ARAM games and having a diverse champion pool. Players may also try to trade with teammates if both players have both champions available to them, whether through purchase or the current weekly champion rotation.

History
ARAM was originally played on Summoner's Rift. After some time, the Proving Grounds map was revamped from being solely for tutorials, to a playable one lane map. Later, the Proving Grounds collapsed due to the sheer awesomeness of battles. The Howling Abyss was released as a new ARAM map, replacing the Proving Grounds, along with the Freljord update and ARAM was was made an official queue.

Map
ARAM is played on the Howling Abyss Field of Justice. The map consists of a nexus, two nexus turrets, an inhibitor, an inhibitor turret, and an additional turret on each side. Bushes are located along the top of the lane, with two Health Relics (per side) and some Poros.
