Illusions (also commonly called illus) are imperfect, weaker copies of heroes, created by abilities or items. They look like and are mostly treated like a hero, but are impaired, as they usually have incoming and outgoing damage penalties, dealing less damage and taking more damage than heroes. They are incapable of casting abilities or using active item abilities, and also have some passive abilities disabled. They also may not drop or pick up items or runes. Illusions yield a little gold and experience based on the hero's level. They do not soak up any experience and gold. Illusions cannot level up, the gold from last hits they make goes to their owners, and do not interfere with kill streaks or counters.

Illusions can be created from an allied, enemy, or the own hero. The illusions copies its appearance, level, Strength attribute symbol.png / Agility attribute symbol.png / Intelligence attribute symbol.png all attributes, attack values, defensive values (e.g. base armor and base magic resistance) and abilities on their current level. All items owned by the main hero are copied as well, including all their stats (although some effects of abilities and items are disabled for illusions).

All illusions deal 60% less damage against buildings, making them weaker in pushing. This reduction stacks multiplicatively with the outgoing damage reduction values most illusions have, and also multiplicatively with the damage reduction hero damage does against structure armor type. However, due to the fact that illusions are based on heroes, their damage scales together with the heroes, making them still a significant pushing tool, especially in later phases of a match.

All illusions are invulnerable for one server tick (0.03 seconds) as they spawn, regardless of which ability that spawns or creates them. Illusions also always play the same spawn sound upon spawning, which are only audible to allies, and the same death sound upon dying in any way, including upon expiring.

Visual Appearance[edit]

Illusions as they appear to allies and enemies.

All illusions have an extra texture layer, which makes them distinguishable from the original hero. There are currently 7 different types of textures which can be seen below.

Allied illusions always appear with the texture layer, making them always look different than the original hero.

Enemies illusions use the blue or the yellow textures appear like the original hero, making it difficult to tell them apart from the real hero. Illusions with the second, third, sixth, or seventh texture appear like illusions to the enemy, meaning enemies do see their illusion textures. However, despite this, the portrait of illusions always appears like the original hero to the enemy.

Illusions do not show damage numbers.

1 Requires Aghanim's Scepter icon.png Aghanim's Scepter.
2 Requires Aghanim's Shard icon.png Aghanim's Shard.

Besides their skin and portrait, their health bar also differs based on whether the illusion is allied or not. Allied illusions have the same health bar as creeps. This also means their mana bar is not visible. Besides this, illusions also have a circle on the left side of the health bar, which indicates their duration.

Enemy illusions use a hero health bar to not make it obvious that they are illusions. They also display the player's or hero's name above them like regular enemy heroes (if the player has the name display toggled on player name or hero name). The player name is based on the owner of the illusion, not of the hero the illusion is based on. This means if an enemy Shadow Demon minimap icon.png Shadow Demon creates illusions of allies, the illusions carry Shadow Demon's player name. When hero names are chosen, instead of player names, it shows the name of the hero the illusion is based on, and not the owner's hero.

Stats[edit]

An illusion's stats, level, ability levels and items are all set upon created and do not adapt to the original hero.

The following traits are copied from illusions based on the original hero:

These trait are not copied and thus do not work for illusions, but their values are displayed in the HUD for camouflaging purposes.

Magic Resistance Bonuses[edit]

Some sources of magic resistance work with illusions and some do not. Magic resistance increasing abilities do not affect illusions, except for Fate's Edict and magic resistance increasing Talent talents. However, in the HUD, magic resistance is always displayed as if they were fully affected.

The following magic resistance sources affect illusions:

The following magic resistance sources does not affect illusions:

1 Requires Aghanim's Scepter icon.png Aghanim's Scepter.
2 Requires Aghanim's Shard icon.png Aghanim's Shard.

Bounty[edit]

Illusions have a gold and experience bounty equal to two times of their level. The gold bounty is granted to the player killing the illusion, while the experience is shared within the default experience area. However, the experience is only granted when the illusion is killed by a player. Expiring illusions, or illusions dying to lane creeps, towers, fountains or neutral creeps do not grant any experience.

The following table shows their bounties on each level:

Level 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

The following illusions grant a fixed 5 Gold and 5XP, regardless of their level:

Copying Buffs and Debuffs[edit]

Usually when an illusion is created, it usually does not copy the buffs and debuffs the original hero has.

There are some exceptions, however, Illusions copy the toggled On / Off statuses of items and of some abilities.

The following buffs are copied by illusions:

1 Requires Aghanim's Scepter icon.png Aghanim's Scepter.
2 The Shapeshift form is copied, but the aura is not. Once Lycan minimap icon.png Lycan returns to his default form, the Shapeshifted illusions no longer move at haste speed and no longer crit.
3 Unholy Strength buff and all its effects are copied (as according to the stats section details), except for the health loss.
4 The buff is copied, but illusions are not granted the attack speed bonus. Only the bonus night vision is copied.
5 Illusions do not revert to melee form upon Metamorphosis expiring.

Attack Modifiers[edit]

Main Article: Attack Modifiers

Attack modifiers are modifiers which apply an effect to a unit's basic attacks. These effects can widely vary, from healing, to damaging or even disabling effects. Most of these modifiers have their own rules. Some attack modifiers work with illusions and some do not, while some of them work partially or have their values decreased for balancing purposes.

The following attack modifiers fully work for illusions:

1 Requires Aghanim's Scepter icon.png Aghanim's Scepter.
2 The damage reductions of Marksmanship and Split Shot are the only reductions which affect illusions.
3 All 3 modifiers of Elder Dragon Form (Corrosive Breath, Splash Attack and Frost Breath) work for illusions. However, the Corrosive Breath debuff placed by illusions deals no damage, the Frost Breath slow debuff doesn't slow the target (although the speed on the HUD is decreased).
4 Only the accuracy works for illusions.

Mana Break[edit]

Mana Break abilities or Talent talents are copied by illusions from the original hero, illusions with Mana Break burns less mana than real heroes.

  • Mana Break icon.png
    Mana Burned per Hit: 28/40/52/64
    Max mana burned per hit: 1%/1.8%/2.6%/3.4% (Talent 1.6%/2.4%/3.2%/4%)
    Burned Mana As Damage: 50%
    Illusion Percentage: 50%
    Does not stack with Diffusal Blade 1 icon.png Diffusal Blade. Illusions burn a reduced amount of mana per hit.
  • Diffusal Blade 1 icon.png
    Mana Burned per Hit (hero): 40
    Mana burned per Hit (Melee Illusion): 12
    Mana burned per Hit (Ranged Illusion): 8
    Burned Mana as Damage: 100%
  • Talent Left 3.png
    Mana Burned per Hit: 20
    Illusion Mana Burned per Hit: 10
    Burned Mana as Damage: 80%
  • Talent Right 2.png
    Mana Burned per Hit: 20
    Illusion Mana Burned per Hit: 10
    Burned Mana as Damage: 80%

Not Copied[edit]

These attack modifiers are not copied upon creation and do not work for illusions:

2 The particle effects of these attack modifiers appear and their sounds play, but their effects are not applied.
3 Tidebringer is always on Autocast for illusions, so they proc whenever off cooldown, but none of its effects are applied.

Active Abilities[edit]

Illusions may not use active abilities and items, but they might inherit ongoing abilities from the original hero if the ability was cast before creating the illusion. Only a few abilities have different effect when the cast is an illusion.

Notable Differences

Casting Fake Abilities[edit]

Within a certain conditions, some abilities causes all illusions owned by the illusion creator within certain range from the target will also fake cast the ability, while the real hero casts the ability.

This is mainly for camouflaging the real hero and their illusions. The illusions still cannot use any active abilities.

These illusions have the following behavior:

  • The illusion play the whole cast animation and cast the fake ability at the same time the real ability is cast.
  • When illusions currently are not having any order and are standing still, they all turn to face the target and cast the ability.
  • When canceling the cast (S), the illusions still play the full cast animation, but do not release the fake ability.
  • When illusions are moving or attacking, they continue to do so and do not turn to face the target. They still play the cast animation, overriding their move or attack animations.
  • They play the whole cast animation and release their fake ability at the same time the real ability is released.
  • These fake abilities do not interact with anything.
Fake Abilities Cast by Illusions

Passive Abilities[edit]

These passive abilities are fully functional for illusions:

1 Warpath does proc when illusions cast abilities. Also, since Warpath always applies a stack on all owned illusions by default, illusions casting abilities get 2 stacks per cast.
2 This is an innate ability. All illusions owned by Faceless Void minimap icon.png Faceless Void are not frozen in time during Chronosphere.
1 The health restore and max movement speed limit works, but not the movement speed bonus, hero detection and vision
2 Only the damage block/reduction works.
3 Only the health regeneration bonus works.
4 Only the damage per second and slow bonus works.

These passive abilities do not work for illusions:

1 The passive components of these active abilities do not work for illusions.

Aura[edit]

These auras are bestowed by illusions upon creation:

1 Despite the illusions not having an Unknown Unit icon.png Astral Spirit, their Natural Order always bestows the armor reduction and the magic resistance reduction aura.
2 Illusions copy the toggled On / Off status of these auras.
3 Burn is weaker on illusions, dealing 35 damage per second, instead of 60.
4 Illusions bestow the Atrophy Aura. When an enemy dies within aura range of an illusion, Underlord gets the damage bonus, if he owns the illusion, otherwise the illusion itself gets the damage.

These auras are not bestowed by illusions upon creation:

1 Requires Aghanim's Scepter icon.png Aghanim's Scepter.

Ability Interactions[edit]

Most abilities treat illusions like regular heroes. However, some abilities have a different effect or interact in a different way with illusions. A few abilities do not affect illusions at all.

Instant Kill[edit]

These abilities instantly destroy illusions when used on them:

1 Requires Aghanim's Shard icon.png Aghanim's Shard.
2 Kills illusions on the first tick, not upon cast.

Creep Duration[edit]

These abilities uses the non-hero or creep duration on them, instead of hero duration:

1 Requires Aghanim's Scepter icon.png Aghanim's Scepter.
2 Requires Aghanim's Shard icon.png Aghanim's Shard.
Ward Units[edit]

These ward units require the creep amount of attacks to destroy them, instead of the hero amount when attacked by an illusion.

Treats Illusions as Non-Hero Units

No Effect[edit]

These abilities do not affect, cannot target, or do not work against illusions:

1 These abilities ignore the death of illusions, so killing them does not make these abilities apply their effects.
2 These abilities do not have a target or do not place their buffs or debuffs on illusions.

Other Interactions[edit]

These abilities have different interactions with illusions. They either do not treat them as heroes, or apply different effects on them.
