Sight

Sight icon Sight is a property of all units and certain abilities, summoner spells, and items in League of Legends that represents a team possessing vision over an area. Inversely, the area of the map in which a team does not have sight over is known as the Fog of War, a common hallmark of the Real-Time Strategy genre. The Fog of War is represented visually as a dark shroud over the map.

Possessing sight is necessary to observe most information about any non-allied units in the game. Such information includes the unit's current location and facing direction, stats and status bar, purchased items, and score. Thus the acquisition and denial of sight is one of the most crucial mechanics of the game.

Sight ranges[]

All units in the game will grant vision up to a specific radius:

Blocking sight[]

There are two obstacles that block regular sight, impassable terrain (which is always opaque to vision granted by units, structures and most items and abilities) and Brushmaker brush (which is opaque towards vision when viewed from the outside inwards and not the reverse). Such barriers will also block vision of any areas that are directly behind them from the sight-granting unit. Units that can directly observe an area around these obstacles are commonly described as having line of sight towards that area.

Sight can be removed in three ways:

Forms of sight[]

Standard sight[]

Ward revealing Fog of War

A ward granting standard sight over the area.

This is the most common form of vision that is able to reveal Fog of War and units altogether.

By default, when an ally uses a Leap Strike unit-targeted spell, including basic attacks, on an enemy unit from inside Fog of War, a 300-unit radius of Fog of War is revealed for the enemy team centered on the attacker which grants vision for 2 seconds after the attack completes.

True Sight icon True sight[]

TrueSight Rek'Sai

A unit True Sight icon revealing a Noxious Trap stealthed trap. A pink eye symbol above a unit indicates they have true sight vision.

This is a unique form of sight that is able to see units concealed in Guerrilla Warfare stealth, who are usually undetectable when under standard sight (such as Ward icon wards and standard sight debuffs). All sources of true sight currently in the game also provide standard sight - otherwise, true sight follows the same rules as standard sight. True sight cannot bypass sight blocked by Nearsight icon nearsight. All Turret icon turrets and some abilities and items and a few others possess a form of true sight, mostly by revealing debuffs.

Sweeper Drone icon Obscured vision[]

Simple Unit Silhouette

A silhouette of a unit observed behind a wall, indicating a form of Sweeper Drone icon obscured vision.

This is a form of detection that does not innately reveal units nor make them targetable in any sort of way. Instead, the unit's position is merely distinguished by their movement and actions or silhouette, revealing their position in the process. The unit is still not visible however, thus being unable to selected for Leap Strike unit-targeted attacks. Obscured vision exists in many effects, the most common ones being in Rek'Sai's Rek'Sai's Burrow Burrow and Oracle Lens Oracle Lens. It is unaffected by Nearsight icon nearsight.

Stealth Ward icon Unobstructed vision[]

Unobstructed vision example

A unit with Stealth Ward icon unobstructed vision being able to see enemies behind walls.

This is a type of sight that permeates through terrain. It allows the unit to be able to see beyond their sight radius if otherwise obstructed by terrain, although they won't be able to see into Brushmaker brush unless they had sight of the inside. Aurelion Sol's Aurelion Sol's Astral Flight Astral Flight, Kayn's Kayn's Shadow Step Shadow Step, Smolder's Smolder's Flap, Flap, Flap Flap, Flap, Flap, Talon's Talon's Assassin's Path Assassin's Path, Zeri's Zeri's Spark Surge Spark Surge and Zoe's Zoe's Portal Jump Portal Jump are the only abilities that benefit from unobstructed vision.

Unobstructed vision nearsight example

A unit with Stealth Ward icon unobstructed vision becoming unable to see out of terrain while Nearsight icon nearsighted.

Nearsight icon Nearsight prevents unobstructed vision entirely; units lose the ability to see behind walls for the duration and if they would be inside terrain, their sight is completely restricted until they move out to open space.
