Experience (champion)

The Experience is the way the Champions level up periodically. There are varius forms to get experience:
 * Champion Kills: Killing an enemy champion rewards a player with an amount of experience determined by the level of the champion slain. The experience gained is equal to 75% of the total experience required for a champion to go from the slain champion’s current level to the next level up. In other words, if a level 7 champion is slain, the total experience gained is 75% of the total experience required for a champion to go from level 7 to level 8, or 862.5 experience points.
 * Assists: A champion is given an assist after damaging an enemy champion that is then killed within 10 seconds. A champion granted an assist will evenly split the total experience reward for killing the enemy champion with all other players that received an assist or landed the killing blow and are within 1600 range of the killing blow.
 * Turret: When a turret is killed all members of the opposing team gain golbal experience points, anywhere on the map, dead or alive. On Summoner’s Rift each turret is worth 300 global experience points.
 * Minions: Killing minions in League of Legends grants an amount of experience upon their death. The experienced gained by the champion is determined by the type of minion as well as the current length of the game. Experience from minion deaths is split between all champions within 1600 range.
 * Neutral Monster: Each type of neutral monster in League of Legends gives a different amount of experience upon death. Only champions of the same team as the champion that landed the killing blow on the monster are granted experience. Experience points are split evenly among all nearby allied champions.
 * Epic Monster: Epic monsters grant experience rewards for an entire team of champions regardless of the location or status of those champions.
