Sight icon.png 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 RTS genre which is represented visually as a dark shroud over the terrain.

Possessing sight is necessary to observe most information about any non-allied units in the game. Such information can include, among many other things, the unit's current location, direction, health, mana, possessed buffs and purchased items, making the acquisition and denial of sight one of the most crucially important skills to learn.

Sight ranges

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

Blocking sight

There are two obstacles that exist towards regular sight - impassable terrain (which is always opaque to vision granted by units, structures and most items and abilities) and Ivern Brushmaker.png 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 - the withdrawal of any sight-granting units, abilities or items from the vicinity, the expiration of a sight-granting debuff or spell, or directly with the Nearsight icon.png nearsight debuff (which currently only exists with Graves' Graves' Smoke Screen Smoke Screen, Nocturne's Nocturne's Paranoia Paranoia, and Quinn's Quinn's Blinding Assault Blinding Assault). Be noted, however, that despite looking like such, Rek'Sai's Rek'Sai's Burrow Burrow does not necessarily nearsight her, as she conserves allied vision.

Forms of sight

Standard sight

A ward granting standard sight over the area.

This is the most common form of vision that is able to reveal the fog of war and units altogether. By default, when attacking an enemy (including Ward icon.png wards) from their team's Fog of War, it will reveal a 400-radius area centered on top of the attacker for 4.5 seconds when their attack completes.

True Sight icon.png True sight

A unit True Sight icon.png revealing a Teemo Noxious Trap.png 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 Teemo Guerrilla Warfare.png stealth, who are usually undetectable when under standard sight (such as Ward icon.png 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.png nearsight. All Turret icon.png turrets and some abilities and items and a few others possess a form of true sight, mostly by revealing debuffs.

Sweeper Drone icon.png Obscured vision

A silhouette of a unit observed behind a wall, indicating a form of Sweeper Drone icon.png 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 Jax Leap Strike.png 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.png nearsight.

Stealth Ward icon.png Unobstructed vision

A unit with Stealth Ward icon.png 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 Ivern Brushmaker.png brush unless they had sight of the inside. Aurelion Sol's Aurelion Sol's Comet of Legend Comet of Legend, Kayn's Kayn's Shadow Step Shadow Step, 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.

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

Nearsight icon.png 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.
