Observer was a summoner spell only available to Riot Games Inc. staff. Upon activation, the fog of war is cleared and all units may be seen. This effect only applies to the user who activated the spell.

Additionally, the caster has their champion vanish, has their other summoner spell disabled, is still allowed to spend gold and can no longer spend skill points.

Observer is no longer available in any realm, instead replaced by Spectator Mode.

Trivia

• Observer was used by David 'Phreak' Turley to record the Ionia vs. Noxus match. A demonstration of the spell's effects during the match can be see here.
  • A similar system was used on the World Cyber Gaming 2010 to record the finale.
• If an enemy Nocturne uses Paranoia, the Observer loses vision for the duration.

• In the old league client, a figure strongly resembling the man in Observer's icon can be seen on the default summoner profile.

Sight

Sight is a property of units, structures, certain summoner spells, items, and abilities that represents a team possessing vision of a target area or unit. It is always center range. A line of vision cannot extend beyond terrain or an unrevealed brush.

---

Sight can also refer to an effect that makes a unit visible regardless of the fog of war or brush, allowing them to be targeted. Standard sight cannot see stealthed units, but True Sight can.

• Nearsight is a crowd control debuff that inhibits sight; allied vision is lost in addition to a reduced sight radius.
• Obscured vision is similar to sight in a way that it can observe units, but does not render units targetable, rather it exposes their position and informs of their presence.
• Unobstructed vision is a form of sight that allows a unit to be able to see their full vision radius, ignoring any obstructions that would otherwise restrict visibility.
• All effects that use unit-targeting require sight of the target. Delayed unit-targeted attacks and spells can cancel if sight of the selected target is suddenly lost.

Vanish

In addition to granting untargetability, vanish briefly hides a unit from the game's renderer, which causes it to become completely undetectable and invisible even to effects such as Oracle Lens. Vanished units are unable to act. As with all untargetability, tethers will still persist on a target that vanishes.

---

Vanish is not considered stealth and does not interact with sight effects.
