Illusions (also commonly called illus) are imperfect, weaker copies of heroes, created by spells 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 mostly incapable of casting spells 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 AoE experience and gold (they cannot level up, and 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, copying its appearance, level, attributes, attack values, defensive values like base armor and base magic resistance and their abilities on their current level. All items owned by the 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 which 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. It does not matter which ability spawns them, this goes for all of them. Illusions also always play the same birth sound (which is only audible to allies) upon spawning, and the same death sound upon dying in any way, including upon expiring.

Visual appearance

Blue illusions as they appear to allies and enemies. Enemy illusions use a hero health bar and display the player names, while allied illusions have a creep health bar and a circle indicating their duration.

All illusions have an extra texture layer, which makes them distinguishable from the original hero. There are 6 different types of textures which can be seen below.

To allies, illusions always appear with the texture layer, making them always look different than the original hero. For enemies, illusions which 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, 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.

Appearance
Portrait
Abilities	Default	Blink, Phantasm, Illusionist's Cape, Manta Style, Mirror Image, Illusion Rune, Disruption, Haunt, Shadow Step	Wall of Replica, Vengeance Aura	Conjure Image, Reflection	Doppelganger	Doppelganger, Juxtapose, Spirit Lance	Dark Portrait
Camouflaged	-	Yes	No	No	Yes	Yes	No

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, as it is only visible when having a hero or creep-hero health bar. 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 when an enemy 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

All 3 attributes of illusions (strength, agility and intelligence) are based on the original hero. They copy their base attributes, the attributes gained from levels, and all item bonuses. They fully benefit from every trait of attributes, health, health regen, mana, mana regen, armor, attack speed, and attack damage. They also copy the hero's movement speed, main attack damage, attack animation (and projectile speed), base attack time, attack range, bonus attack range, base magic resistance, main armor, base health and mana regen, vision, collision size and turn rate. An illusion's stats, level, ability levels and items are all set upon spawn and do not adapt to the original hero.

Besides copying all the base stats of heroes, these bonus stats (from items, talents or passive abilities) are also copied:

• Attack range
• Attack speed
• Attributes
• Base attack time
• Base attack damage
• Evasion
• Health
• Mana
• Health regeneration
• Mana regeneration
• Movement speed
• Spell damage amplification
• Status resistance
• Vision

These bonus stats are not copied and thus do not work for illusions (although some of them are displayed in the HUD still):

• Attack damage
• Armor

And finally, these bonus stats are inconsistent; some sources work, some do not:

• Magic resistance

Magic resistance

Magic resistance increasing effects do not affect illusions, except Fate's Edict, which fully works.

Magic resistance reductions are inconsistent with illusions. They either do, or do not affect them. However, in the HUD, magic resistance is always displayed as if they were fully affected.

Magical damage barriers fully work for illusions.

These abilities do reduce the magic resistance of illusions:

Working magic resistance sources

• Elder Titan – Natural Order
• Ethereal Blade – Ether Blast
• Ghost Scepter – Ghost Form
• Necrophos – Ghost Shroud
• Pugna – Decrepify

These abilities do not reduce the magic resistance of illusions:

Not working magic resistance sources

• Ancient Apparition – Ice Vortex
• Skywrath Mage – Ancient Seal

Bounty

Illusions have a gold and experience bounty equal to their level times 2. 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
Bounty	2	4	6	8	10	12	14	16	18	20	22	24	26	28	30	32	34	36	38	40	42	44	46	48	50	52	54	56	58	60

The following illusions grant 5 gold and experience, regardless of their level:

• Juxtapose (created by Phantom Lancer and from illusions)
• Spirit Lance
• Wall of Replica

Copying buffs or debuffs

Usually when an illusion spawns, it does not copy the buffs and debuffs the original hero has. There are some exceptions with buffs though. However, they do copy toggle statuses of items and of some abilities.

The following buffs are copied by illusions:

Buffs copied by illusions

• Alchemist – Chemical Rage
• Alchemist – Aghanim's Scepter Synth
• Armlet of Mordiggian – Unholy Strength¹
• Dragon Knight – Elder Dragon Form
• Lone Druid – True Form
• Lycan – Shapeshift²
• Moon Shard – Consume³
• Morphling – Attribute Shift
• Troll Warlord – Berserker's Rage
• Undying – Flesh Golem

¹ The Armlet buff gets copied and applies all its effects (as according to the stats section details), except for the health loss.

² The wolf form is copied, but the aura is not, so once Lycan returns to his default form, the Shapeshifted illusions no longer move at max speed and no longer crit.

³ Although a consumed Moon Shard's buff is copied, illusions are not granted the attack speed bonus. Only the bonus night vision is applied.

Attack modifiers

These attack modifiers fully work for illusions:

Working attack modifiers

• Abaddon – Curse of Avernus
• Anti-Mage – Manabreak²
• Brewmaster – Drunken Brawler Critical Strike

¹ The reductions of Split Shot and Marksmanship are the only reductions which affect illusions.

² Mana Break and Diffusal Blade burn less mana for illusions than for real heroes.

³ All 3 modifiers of Elder Dragon Form work for illusions, however, the poison debuff placed by illusions deals no damage, the slow debuff doesn't actually slow target (though the speed on the HUD is decreased).

⁴ Only the accuracy works for illusions.

These attack modifiers do not work for illusions:

Not working attack modifiers

• Abaddon – Curse of Avernus¹
• Abyssal Blade – Bash
• Battle Fury – Cleave²

¹ Places buff on the illusions on each attack, but does not apply the debuff on attack targets.

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.

Passive abilities

These passive abilities fully work for illusions:

Working passive abilities

• Abyssal Blade – Damage Block
• Aether Lens – Aethereal Focus
• Axe – Counter Helix
• Bristleback – Warpath¹

¹ Warpath does proc when illusions cast spells. Also, since Warpath always applies a stack on all owned illusions by default, illusions casting spells get 2 stacks per cast.

These passive abilities do not work for illusions:

Not working passive abilities

• Abaddon – Borrowed Time¹
• Alchemist – Greevil's Greed
• Anti-Mage – Counterspell¹
• Lua error: Found no Cargo data for "Bloodstone - Mana Battery".

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

And finally, these passive abilities work partially for illusions:

Partially working passive abilities

• Bloodseeker - Thirst
  
  Heal and speed limit removal work for illusions, but movement speed bonus and detection/vision do not.
• Bristleback - Bristleback
  
  Illusions gain the damage reduction, but not the passive Quill Spray procs.
• Dragon Knight - Dragon Blood
  
  Illusions benefit from the health regeneration, but not from the armor.
• Razor - Storm Surge
  
  Illusions benefit from the base bonus speed, not the self bonus speed.
• Tidehunter - Kraken Shell
  
  The Damage Block works for illusions, but the dispel effect does not.
• Timbersaw - Reactive Armor
  
  Illusions gain stacks and benefit from the health regeneration, but not from the armor.
• Viper - Corrosive Skin
  
  The damage and slow work for illusions, but they do not gain magic resistance.

Auras

These auras are bestowed by illusions:

Bestowed auras

• Assault Cuirass – Assault Aura
• Beastmaster – Inner Beast
• Buckler – Buckler Aura²
• Centaur Warrunner – Retaliate Aura

• Elder Titan – Natural Order¹

• Vladmir's Offering – Vladmir's Aura

¹ Despite the illusions not having an Astral Spirit, their Natural Order always bestows the armor reduction and the magic resistance reduction.

² Illusions copy the toggle status of these auras.

³ Radiance Aura is weaker on illusions, dealing 1.5 damage, 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.

⁵ Illusions do not spawn a Vengeance illusion upon death.

These auras are not bestowed by illusions:

Not bestowed auras

• Drow Ranger – Marksmanship Agility Aura
• Gem of True Sight – True Sight
• Lycan – Shapeshift Speed and Crit Aura
• Terrorblade – Metamorphosis Aura
• Wraith King – Wraith Delay Aura

Active abilities

Most illusions cannot use active abilities and items. The only exception are Talent-upgraded Vengeance illusions, which are allowed to cast Vengeful Spirit's abilities.

Almost all active abilities work normally for illusions, although there is currently no way for illusions to regularly use them. Only very few have a different effect when the caster is an illusion.

Notable differences

• Abaddon - Borrowed Time
  
  Even when the illusion is allowed to cast spells, Borrowed Time still does not auto-activate when below 400 health.
• Batrider - Firefly
  
  When the casting illusion dies, the fire trail immediately disappears, instead of staying for its remaining duration.
• Chen - Holy Persuasion
  
  All persuaded units die instantly when the illusion dies.
• Doom - Infernal Blade
  
  Cannot be used by illusions at all. Attempting to cast this makes the illusion perform a regular attack.
• Earth Spirit - Enchant Remnant
  
  Illusions cannot cast this spell.
• Elder Titan - Astral Spirit
  
  When the illusion dies while having the Astral Spirit out, the Astral Spirit dies as well. It does not return.
• Enchantress - Nature's Attendants
  
  When the illusion dies, Nature's Attendants ends immediately, instead of continuing to heal nearby allies for the remaining duration.
• Leshrac - Diabolic Edict
  
  When the illusion dies, Diabolic Edict ends immediately, instead of continuing to damage nearby enemies for the remaining duration.
• Leshrac - Lightning Storm
  
  When the illusion dies, Lightning Storm immediately stops bouncing.
• Medusa - Mana Shield
  
  Although it can be toggled, Mana Shield does not work for illusions at all.
• Mirana - Moonlight Shadow
  
  Since the spell does not affect illusions, the casting illusion is not turned invisible.
• Nyx Assassin - Burrow
  
  Illusions cannot cast this spell.
• Ogre Magi - Unrefined Fireblast
  
  Illusions cannot cast this spell.
• Phantom Assassin - Stifling Dagger
  
  Only attack modifiers which work for the illusion can proc. This means Stifling Dagger cast by illusions can, for example, never bash.
• Phoenix - Supernova
  
  When the illusion dies or expires during Supernova, the Supernova does not end, continuing to damage and then stun enemies at the end.
• Rubick - Fade Bolt
  
  When the illusion dies, Fade Bolt immediately stops bouncing.
• Sand King - Epicenter
  
  When the illusion dies, Epicenter ends immediately, instead of continuing to release its pulses.
• Spirit Breaker - Charge of Darkness
  
  Even though Greater Bash does not work for illusions, Charge of Darkness still applies the AoE bash.
• Spirit Breaker - Nether Strike
  
  Even though Greater Bash does not work for illusions, Nether Strike still applies the AoE bash.
• Timbersaw - Chakram
  
  Illusions cannot cast the blue Chakram.
• Treant Protector - Eyes In The Forest
  
  Illusions cannot cast this spell.
• Tusk - Walrus Kick
  
  Illusions cannot cast this spell.
• Visage - Soul Assumption
  
  Illusions do not have the charge meter above them.
• Zeus - Arc Lightning
  
  When the illusion dies, Arc Lightning immediately stops bouncing.

Ability interactions

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.

These abilities instantly destroy illusions when used on or against them:

Instantly killing illusions

• Dagon – Energy Burst
• Dazzle – Poison Touch (Hex)²
• Disruptor – Glimpse
• Lion – Hex
• Lion – Mana Drain¹
• Pugna – Life Drain¹
• Scythe of Vyse – Hex

² Requires Aghanims Shard.

These abilities treat illusions as creeps, instead of heroes:

Treating illusions as creeps

• Abaddon – Borrowed Time aura
• Ancient Apparition – Ice Blast
• Bloodseeker – Thirst
• Lua error: Found no Cargo data for "Bloodstone - Mana Battery".
• Chen – Hand of God
• Dark Seer – Wall of Replica
• Earth Spirit – Rolling Boulder

• Guardian Greaves – Guardian Aura
• Lua error: Found no Cargo data for "Invoker - EMP".
• Io – Spirits
• Kunkka – Ghostship
• Mirana – Moonlight Shadow

• Phoenix – Supernova¹
• Pudge – Flesh Heap

• Undying – Decay
• Undying – Tombstone¹
• Urn of Shadows – Soul Release
• Visage – Soul Assumption
• Witch Doctor – Paralyzing Cask

¹ Illusions require the creep amount of attacks to destroy these, instead of the hero amount.

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

Not affecting or working against illusions

• Alchemist – Greevil's Greed¹
• Alchemist – Aghanim's Scepter Synth²
• Broodmother – Spin Web²
• Necrophos – Heartstopper Aura
• Observer and Sentry Wards – Share Wards²
• Rubick – Spell Steal
• Shadow Fiend – Necromastery¹
• Tango – Devour²
• Templar Assassin – Psi Blades
• Underlord – Atrophy Aura¹
• Viper – Nethertoxin

¹ These abilities ignore the death of illusions, so killing them does not make these abilities apply their effects (Attack damage from Atrophy Aura applies to illusions).

² These abilities cannot target, or do not place their buffs or debuffs on illusions.

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

Other interactions

• Bounty Hunter - Track
  
  Illusions do not provide any bounty when dying while tracked.
• Bristleback - Warpath
  
  Warpath places its buff/grants a stack to the caster and all illusions under the caster's control.

  Illusions deal 75% less damage against protected buildings, instead of 25% like any other unit. They also deal 60% less damage against unprotected buildings.
• Elder Titan - Astral Spirit
  
  Damages illusions, but does not count them for the damage and speed buff.
• Legion Commander - Overwhelming Odds
  
  Deals additional damage based on current health to illusions. Illusions are treated as creeps.
• Legion Commander - Duel
  
  Does not grant victory damage when defeating an illusion in a Duel.
