Cast range ( ) is the distance at which a hero may use an ability on its target. Casting an ability beyond its cast range will cause the hero to move within the cast range, and cast the ability.

Cast range can be increased by certain abilities and certain specific talents. There are currently no Talent talents that increases a heroes' basic cast range.

Collision Size Bonus Range[]

An ability's maximum or actual cast range is dependent on the hero's collision size and the ability's targeting type.

No Target[]

Abilities with the no target requirement are immediately cast as soon as its button is pressed. Many of these abilities do not have a cast time. They cannot directly target a unit or a point. Same goes for abilities that can be toggled On / Off. Therefore, only flat cast range bonuses are counted and collision size is not.

The cast range for no-target abilities is defined as:

With cb being the ability's base cast range and ci the cast range bonus sources.

Vector Targeting[]

Cast range bonuses increases all vector targeting ability's cast range as usual, using the same formula as above, but not area of effect.

Target Area[]

Cast range bonuses increases all area-targeted ability's cast range as usual, using the same formula as above, but not area of effect.

Target Unit[]

See also: Attack Range

Target unit abilities require the caster to directly target a unit, and cannot be used on the ground. The actual range at which a unit-targeted ability (or attack) is able to cast is a little further than the value shown due to having a motion buffer range, which is 250 range. This means that if a unit moves out of cast range, but is still within 250 range more than the ability's cast range when the ability's cast point completes, the unit-targeted ability will be cast.

Unit targeted abilities also considers the range from the caster's edge to the target's edge, based on the collision size of the caster and the target.

The cast range for unit-targeted abilities is defined as:

With cb being the ability's base cast range, ci the cast range bonus sources, cols the collision size of the caster and colt the collision size of the target.

Motion Buffer[]

The following abilities have different motion buffer range values from the default 250. If the targeted unit is out of this range, the ability will be cast once the target and/or the caster moves within default range.

Abilities with Motion Buffer Range


Example[]

Luna minimap icon.png Luna casting Lucent Beam on an enemy Abaddon minimap icon.png Abaddon, what is the maximum cast range of Lucent Beam in this example?
Cast range values:
Collision size values:
Lucent Beam's actual cast range in this example is 1098, instead of 800.

Target Point[]

Point-target abilities require the caster to target a point or an area. For point-targeted abilities, both flat cast range bonuses and the range from the caster's edge to the target's edge, based on the collision size of the caster and the target is considered, but not the motion buffer range.

The cast range for point-targeted abilities is defined as:

Example[]

Morphling minimap icon.png Morphling is casting Waveform, what is the maximum cast range for Waveform?
Cast range values:
Collision size values:
Waveform has a maximum 1024 cast range in this example.

Attack Modifiers[]

All active attack modifier-based abilities' cast range is based on the caster's attack range. The cast range can be further increased by other attack range bonuses. However, it is not affected by cast range bonuses.

Some of these abilities have different cast range depending on the situation, the ability uses the ability's cast range when cast manually with Hotkey and it uses the caster's attack range while Autocast is active.

1 Requires Aghanim's Scepter icon.png Aghanim's Scepter.
2 Requires Aghanim's Shard icon.png Aghanim's Shard.
3 Can be further increased by other melee attack range bonuses (e.g. Penta-Edged Sword icon.png Penta-Edged Sword).
4 Uses caster's attack range while Autocast is active, and uses cast range while manually cast.
5 Can be further increased by both attack range bonuses and cast range bonuses.

Other Cast Range Bonuses[]

Some abilities have different cast range or provides cast range bonus in specific conditions.

Patch History[]

Patch
Description
  • Hovering over a unit's portrait now displays a range finder for their current vision range.
  • Ability ranges are now shown when hovering over enemy hero abilities (shows the values for the max level ranges).
  • Fixed some cases where the cast range range-finder wouldn't match the actual cast range (i.e. Talent Earth Spike).
