Disables (also called crowd control, or CC) refer to any abilities or status effects that prevent, impede, or otherwise inhibit a Hero from acting. Disables come in many different varieties, and most Heroes have access to some form of disable. Sometimes "disabled" or "fully disabled" refer to stun.

- 1 Does not prevent turning.
- 2 Certain abilities can still be cast while stunned if stated in ability notes, e.g. .
Stuns are the most common and most dependable kind of disable. Upon getting stunned, the unit stops its current order and stands still until the effect expires. While stunned, the unit cannot move, attack, cast abilities or use items.
It also interrupt all channeling abilities, such as using . In general, stuns can be categorized into three types, with each using a different modifier to stun the target(s). Stuns from the same group use the same modifier, therefore they refresh each others' duration based on when they affect the target and do not extend its stun duration.
|Stunned||Do not place their own individual modifiers, but refresh each other.|| (Regular Stun)|
|Bash||Do not place their own individual modifiers, but refresh each other.|
|Unique||Uses a custom modifier, meaning each of them place their own modifiers on their targets.|
Certain stun abilities requires the caster to channel the ability in order to stun the affected target(s), or it applies negative effects onto the caster themselves. These abilities mostly use the Unique Modifier (e.g. and ).
Sleep is a rare status effect that completely disables those affected for the entire duration. However, units affected can be awaken by dealing damage to them. Some sources of Sleep provides invulnerability (e.g. ), while some do not (e.g. ).
Cyclone is a status effect that causes afflicted units to be lifted up, completely disabling them, but also rendering them invulnerable. Some cyclone sources also apply a basic dispel on the target. While being lifted up into the air, other units can pass below it. Sources of Cyclone are and .
A type of status effect that reduces the afflicted units movement speed by a percentage, and/or attack speed by a flat value of their current speeds. In general, slows from different sources stack with each other, but multiple of the same instance do not, but refresh their duration instead. There are some exceptions to this.

Hex applies multiple types of disables – silence, mute and disarm on the affected target and set its movement speed to a fixed value. All sources of hex have an instant (0 second) cast time and instantly destroy illusions except strong illusions. Hexed heroes are still treated as heroes by abilities. Sources of Hex are and .
Forced Movement is a status effect that changes a unit's position. This movement is completely unrelated to the unit's movement speed and works on them while disabled. Most forced movement abilities prevent the affected unit from acting during, but some still allows the unit to attack, turn and cast abilities (and items).
|Forced Movement||Disabled Aspect / Definition||Examples|
Root (formerly known as Ensnare) is a status effect that prevents affected units from moving, and from casting most mobility abilities. However, it does not prevent the affected units from turning, casting other abilities or using most items. Some root sources also disarm the affected units (and disarming roots were formerly known as Entangle).
|Root Types||Disabled Aspect / Definition||Examples|
Leash disables casting several mobility abilities (e.g. Blink-based abilities) and it shares a few interactions with the Root mechanic. Although, Leash prevents casting certain abilities, it does not cancel them when getting leashed while the ability is cast. Leash also does not interrupt channeling, but it always cancels 's teleport.
The mechanics for Leash sources works differently depending on the ability, and are detailed in its respective ability notes. For example, affected heroes leashed withinduration are stun if they move too far from the leashed point; heavily slows the leashed hero when it tries to move away from the leashed point etc.
A trap hinders a unit from moving, similar to how cliffs hinder a unit from moving. These abilities either create an impassable obstacle, or create a barrier or a leash which prevent units from passing by heavily slowing the unit if it tries to pass through.
|Trap Types||Aspect / Definition||Examples|
Taunt forces the affected unit to drop any of its current order, and start attacking the taunting unit instead. This means it fully cancels attack orders against other units, ability cast orders and channeling. If the taunted unit is out of attack range, it moves towards the taunt source until within attack range. The unit only uses regular movement to get closer to the taunting unit, it does not utilize abilities to close the gap.

Hide renders the unit unable to move, attack, cast abilities and items. All Hide sources also turn the affected unit invulnerable. Hidden units still gain ExperienceXP and Gold . While hidden, a unit cannot be affected by any abilities, with very few exceptions (e.g. ). For example, a would just fly through and possibly hit a unit behind the hidden unit.
Disarm prevents the afflicted unit from attacking, although they can still cast abilities. When a disarmed unit is ordered to attack, they will attempt to stay within attack range of their target but will be unable to act. After the disarm's duration is over, they will resume attacking normally. A disarm prevents the affected unit from attacking. It still can be attacked by other units. Sources of Disarm are and .
Ethereal, sometimes referred to as ghost form, is a type of status effect that makes affected units immune to all physical damage, grants them attack immunity, while also disarming them. It also reduces their magic resistance, causing them to take additional magical damage. Affected units are able to control every other aspect of their character.
The magic resistance reduction of multiple ethereal effects does not stack, the one with higher value takes priority, and it is defined as
Eth = (1 - MAX Ethereal Magic Resistance Reduction) Sources of Ethereal are and .
Blind is a debuff that makes a unit miss upon attacking other units and sources of blind effects stack additively with each other. Blinds work fully independently from evasion. Sources of Blind are and .
Stuns (including Shackle, Sleep and Cyclone), Forced Movement, Hide and Taunt effects do not prevent the player from giving orders to their units. The given order is executed by the unit as soon as the disable expires. There are only very few abilities which can be cast normally while affected by these disables:
- 1 Requires talent.
- 2a Requires .
- 2b Requires .
However, some disables prevent giving orders to units. They also prevent casting the aforementioned abilities.
When an order is prevented, the player cannot even select a target in case of targeted orders like a unit-targeted ability. In such case, the order remains selected (i.e. a unit-targeted ability stays selected when attempting to cast it while silenced, and the player has to manually deselect it).
When giving orders is disabled, a red on-screen error message appears, telling the player why the order cannot be given. The text is usually accompanied by an error sound. The message and sound varies based on the disable.
The following status effects disable giving orders:
|Status Effects||Disabled Aspect / Definition||Examples|
|Ethereal||Fully prevent ordering attacks on the Ethereal Unit.|
|Fear||Runs away from caster towards a certain direction and fully prevent any orders.|
|Hypnosis||Pulled towards caster and fully prevent any orders.|
|Leash||Limited movement capabilities and fully prevents ordering certain abilities.|
|Mute||Fully prevent item cast orders, except ability casts.|
|Root||Rooted on spot and fully prevents ordering certain abilities.|
|Silence||Fully prevent any abilities order, except item casts.|
Besides the named disables, the prevention of giving orders is also partly a disable on its own. Several abilities completely prevent the player from giving the affected units any order, while the disable the ability uses does not. The following abilities fully prevent giving orders:
- The caster may only be ordered to usewhile Infested.
- The targeted ally may not be given any orders for its duration.
- May only be ordered to useduring Supernova.
- The targeted ally may not be given any orders until the lock duration is over.
Pause was an effect that completely rendered the target unable to move, attack, cast spells or items, disabled most passive abilities and caused buffs and debuffs to not tick down for the duration. It also prevented it from gaining experience.
- Examples of pause were , , and .
