Zuschauermodus

Spectator Mode, once known as the summoner spell "Observer", is a mode in League of Legends that allows a player to watch, but not physically take part in a game. It was first introduced at the Dreamhack Season One Championship but since it's release it has seen little use. On November 10, 2011, it was reintroduced to custom games for beta testing, and has since been implemented into normal games but with its limits to prevent any cheating among players.
