Vision describes what a unit can and cannot see within a circular area from its current location and state. Places a unit cannot see are filled with the Fog of War, a dark mist that hides enemy units inside of it. Allied units cannot be hidden by the fog of war. Invisible units cannot be seen even when outside of the Fog of War, unless they are revealed by a source of True Sight. Trees and higher elevation block a unit's vision if it has ground vision. Flying vision is unobstructed by trees and elevation. Abilities can grant vision over areas as well, usually for a short amount of time and limited to their area of effect.
All vision is shared within a team, which means that everything allied units see can be seen by the player as well. This includes allied player-controlled units, as well as NPC units, like lane creeps and buildings.
Contents
Fog of War[]
All areas outside of friendly vision are constantly covered by the Fog of War. Any non-friendly units within the Fog of War cannot be seen or directly targeted, however they can still be hit by non-targeted spells. To unveil units in the Fog of War, an allied unit must gain vision over that area.
If an enemy enters the fog of war during the cast time of an ability, the cast gets canceled. However, attacks do not cancel if their targets enter the fog of war during the attack animation.
Elevation[]
Units cannot see areas that are on higher elevations than them.
The Dota 2 map's cliffs and valleys shape the battle, determining both where units can move and what they can see. Units with ground vision cannot see areas that are on higher elevation than them. For example, a unit standing in the river (which is the on the lowest elevation) cannot see anything past the cliffs surrounding the river, or beyond the ramps leading out of the river.
On the other side, units standing on higher elevation effectively have unobstructed vision on lower elevation. For example, a unit standing on an elevated ward spot can see the entire surrounding, unobstructed by nearby trees, regardless of their vision type.
Units with flying vision do not have their vision obstructed by higher elevations.
Trees[]
Amount of vision blocked by single tree changes based on proximity to it.
Besides blocking pathing, trees also block vision for units on the same elevation as them, and for units one elevation above them. Trees block vision like how objects cast shadows: The closer the object is to the source of light, the bigger and wider the object's shadow gets. The closer a unit is to a tree, the more vision is blocked by the tree, blocking out an entire section of the circular vision area of the unit. The exact numbers for these are unknown.
The small trees created by Iron Branch, Ironwood Tree, Woodland Striders, and Sprout have a narrower vision blocker than the regular trees on the map.
Units with flying vision do not have their vision obstructed by trees.
Vision blockers[]
Besides trees and higher elevation, there are also some artificial vision blockers. Roshan's pit entrance is sealed by a vision blocker, preventing units from outside the pit from seeing inside it, and units from inside to see outside of the pit. Both fountains have a vision blocker at their stairs as well, preventing enemies of the respective teams from seeing inside the fountain area. However, this vision blocker is redundant, since the fountains' higher elevation creates the same effect.
Currently, no ability creates artificial vision blockers.
Units with flying vision do not have their vision obstructed by vision blockers.
Time of day[]
Another factor in vision range is the current time of day. Most units' vision range is lower during nights and higher during the day, although there are exceptions to this, with some units having lower vision during the day and higher at night, and some units having the same vision regardless of daytime.
Base vision ranges[]
Most units have day and night vision, only very few have absolutely no vision. These values can be altered with vision bonuses and reductions.

Types of Vision[]
There are 2 types of vision, ground vision (also known as obstructed vision) and flying vision (also known as unobstructed vision). Ground vision is impaired by higher elevations, trees, and vision blockers, while flying vision is completely unhindered.

Sources of vision[]
Units are not the only entities with vision. A lot of abilities are able to create vision cells of varying sizes on the world, revealing an area of a fixed duration.
Caster vision[]
Caster vision granted over Bane to his enemies for casting Brain Sap on them.
Caster vision is a vision cell granted to the victims of targeted spells and attacks. Whenever a unit casts a spell (except Charge of Darkness) on an enemy within 1800 range, or performs an attack on them, the enemy gains 150 radius ground vision around the casting or attacking unit which lasts for 2 seconds. This vision prevents players from easily and constantly harassing enemies from the fog of war, especially with long-distant spells that can be spammed easily like Arcane Bolt, or with ranged attacks.
Only one of these vision cell can exist per unit. This means if a vision cell already exists from a previous targeted order, performing another targeted order within the previous vision cell's duration does not create a second vision cell. Instead, the location of the previous vision cell gets updated, its duration gets reset, and its vision type is changed to flying vision.
Caster vision is also applied upon launching an attack. The result of the attack does not matter, if the attack is executed, the vision is granted.

Shares the target's vision, as well as the vision of the secondary target it binds to. - Duration: 2

Shares all hit enemy heroes' vision as long as they create a shadow path still. - Shares the target's vision until the charge stops, either upon reaching it, or when canceled earlier.
Exposing[]
Several abilities are capable of exposing an enemy's model through the fog of war, without truly providing vision over them. This means their surroundings are still shrouded by the fog, but they are visible and targetable as if they were not within the fog of war. Exposed enemies are treated as visible units by every spell.
Exposing an enemy does not cancel out the effects of invisibility, although it does make their silhouette visible. An exposed invisible enemy has its location revealed, and can even be selected like a visible enemy, but is still almost fully treated as an invisible unit. This means it still cannot be targeted by attacks or single-targeted abilities, and still counts as invisible in terms of abilities affecting them, with a very few exceptions. Some sources of exposure also provide True Sight to fully reveal the enemy, but not all do.
Exposing is a default component of shared vision, so that all spell listed in the previous section expose enemies as well. Besides them, the following abilities expose enemies.
- Health threshold: 25%
Exposes every enemy hero once their health drops below the given percentage. Provides True Sight. - Duration: 30
Exposes the target enemy. Provides True Sight. - Duration: 10
Exposes the target enemy. Does not provide True Sight. - Duration: 18
Exposes the target enemy. Provides True Sight. - Duration: 1
Exposes the target enemy during the cast time. Does not provide True Sight. - Exposes the current target of the tranced hero. Does not provide True Sight.
- Exposes the target until the Snowball crumbles. Does not provide True Sight.
- Duration: 16
Exposes the latch targets. Does not provide True Sight.
Vision interaction with spells[]
Generally, unit-targeted spells require vision over the target, while ground targeted or non-target spells may be cast regardless of vision. Once cast, a spell usually works regardless of vision. Area effects usually do not require vision to affect enemies. Some non-targeted spells that do the targeting themselves may require vision over enemies. There are exceptions to all of these.

Recent Changes[]
- Firefly no longer grants flying vision while active.
- Vision and Fog of War can now be any numerical value, rather than specific intervals (previously it was 0, 64, 192, 320, 448, 576, 704, 800, 832, 960, 1088, 1216, 1344, 1472, 1600, 1728).
- Previously if you had a vision between the fixed intervals, it would clamp to a fixed value.
- Mystic Snake no longer requires Fog of War vision to bounce.
