Demonic Purge
Demonic Purge

Shadow Demon is a menacing ranged intelligence hero who is most powerful in the early game for his strong set of spells. Disruption takes an enemy or ally out of the fight, banishing them to a shadowy realm and returning them a short time later along with two hostile demonic illusions. Soul Catcher can curse his victims with vulnerability, instantly removing a fraction of their current health. His Shadow Poison can harass any unfortunate foe he encounters, gradually dealing more damage with each application until the Shadow Demon releases the poison from the target in a powerful, damaging burst. Demonic Purge, his ultimate, is key for securing kills: The Shadow Demon greatly slows his fleeing victim and removes all dispellable buffs, crippling and weakening them, while also applying a Break that disables almost all passive skills when upgraded with Aghanim's Scepter. Heavily reliant on the coordination and effectiveness of his own team, Shadow Demon proves to be incredibly strong as a defensive support by keeping his teammates alive reliably and as an offensive support by amplifying damage and endlessly slowing enemies until they're unable to escape. A formidable ally, who requires little farm to contribute greatly to his team, good positioning and timing from Shadow Demon's spells can make all the difference, and makes for one of the most potentially powerful supports well into the late game.


Shadow Demon minimap icon.pngShadow Demon
▶️ "Who toys with demons will find himself toyed with."
Among the sovereign Demons with explicit access to this world, Doom scarcely bothers with the affairs of Noninfernals and Lesser Spectral Consorts, while Shadow Fiend passes through almost exclusively on collecting expeditions. The Shadow Demon, however, has always taken a deep and abiding interest in the material plane, as if sensing that mastery of this gritty dimensional nexus might be the key to total domination of all realities.

Summoned first by minor wizards, the Shadow Demon granted every wish and put on increasingly impressive displays of power until he had the full attention of the greatest demonologists, and through them the various lords, tyrants, autarchs and heirophants who depended on sorcery to buttress their mundane power. So great was his deception that all his summoners considered themselves the master and Shadow Demon the servant; meanwhile, he eroded their identities and made their minds his own. In the end, most members of the cult were hollow puppets, extensions of his evil will.

What Shadow Demon's next step would have been remains open to speculation, for around this time, Nevermore the Shadow Fiend bit into a particularly nasty-tasting soul and discovered that it held nothing but a foul nougat of Shadow Demon's essence. Alerted that a coup was underway, and that the ancient equilibrium of the Umbral Pact was about to be destabilized, Doom and Shadow Fiend briefly joined forces to destroy the burgeoning cult. Combining spells of incredible force, they undid Shadow Demon's centuries of patient work, reducing his cult to smithereens—and all its members to a bloody splatter. Nothing remained except a tiny speck of demon shadow. Immortal and irreducible, this mote of evil was enough to seed the Shadow Demon's next scheme, and in fits and starts, over further centuries, he began to regroup.

Whatever that speck of shadow touched, it tainted, and its influence gradually grew. A chaos of damaged parts pulled together, reknit, and combined to give Shadow Demon a form even stronger than his former. He is all but complete now, and his plan for infinite dominion lacks all of its former weaknesses. It would seem that such a being of pure malice and malevolence, a threat to all creation, would be forever out of place in our world...yet Shadow Demon does not lack for followers.


Disruption illusion as they appear to allies.

Disruption icon.png
Banishes the targeted unit from the battlefield for a short duration. Upon returning, two illusions of the banished unit are created under Shadow Demon's control.

Buff modifier_invulnerable: Dispellable with death only.
The pain of deception comes not while it happens, but when it is revealed.


  • Always creates the illusions, even when cast on allies or self.
    • Can be cast on illusions, creating illusions based on the original hero.
  • When the target turns invisible during Disruption, the visual effects turn invisible as well.
  • The illusions are created at the end of the duration. When the target dies during Disruption, no illusions are created.
    • The current health of the illusions is determined upon casting Disruption, not upon creating the illusions at the end of the duration.
    • This means any health loss caused by Shadow Demon's abilities during Disruption do not affect the health of the illusions that are about to spawn.
    • All other stats like hero level or current mana are determined upon creating the illusions.
  • The targeted unit's position is not shuffled with the possible illusion's position. It always reappears between the 2 illusions.
    • The illusions spawn 108 range away from the hero if the hero has a collision size of 24, and 72 if the collision size is 8.
    • Each illusion appears either north, east, south or west from the hero and face the same direction as the hero does.
  • The illusions carry the caster's name, not the targeted unit's player name, revealing that they are illusions when not cast on self.
  • The Disruption Charges Talent talent instantly grants 1 extra charge.

Soul Catcher
Soul Catcher icon.png
Captures the soul of enemy units in an area, causing them to lose a percentage of their current health. Shadow Demon temporarily gains Spell Amplification for each hero's soul captured. When the debuff is removed, the units gain half of the lost health back. Units under the effect of Disruption can still be affected by Soul Catcher.
Cast Animation: 0.3+0
Cast Range: 700
Radius: 175/200/225/250
Current Health Removed: 20%/25%/30%/35%
Self Spell Damage Amplification per Hero: 5%/7%/9%/11%
Duration: 10
Cooldown: 26/24/22/20 (Talent 20/18/16/14)
Mana: 80/100/120/140
Does not pierce spell immunity. Debuff persists if it was placed before spell immunity.
Buff modifier_shadow_demon_soul_catcher_spell_amp: Dispellable with any dispel.
Debuff modifier_shadow_demon_soul_catcher: Dispellable with any dispel.
Trying to resist the Shadow Demon's corruption is mostly a useless endeavor.


  • Directly manipulates enemies' health by taking away a percentage of health.
    • This ability does not deal damage, and therefore it bypasses every damage manipulating effect.
  • The returned health at the end of the duration is based on how much health was removed initially. It is not based on the current health upon expiring.
  • Multiple instances of the debuff fully stack.
  • If enemy heroes (including clones, excluding illusions and creep-heroes) are hit, Shadow Demon gains a buff that lasts for 10 seconds.
    • The buff gains stacks based on the number of heroes that were hit by that cast. The number of stacks is visible on the buff icon.
    • The buff is independent from the debuff placed on the enemies, dispelling the debuff does not take away a stack from the buff.
    • Re-casting the ability so that it hits enemy heroes again refreshes the buff and updates the stack count based the number of heroes hit with the new cast.
    • This means the number of stacks is limited to the amount of heroes in the enemy team.
  • Applies generic outgoing damage amplification on Shadow Demon. Stacks additively with other sources of generic outgoing damage manipulation.
    • The amplification affects only spell damage Shadow Demon deals that is not flagged as HP removal. Attack damage is not amplified.
  • This is how much spell damage amplification Shadow Demon gains after hitting a certain amount of heroes:
    • 1 Hero: 5%/7%/9%/11% spell damage amplification.
    • 2 Heroes: 10%/14%/18%/22% spell damage amplification.
    • 3 Heroes: 15%/21%/27%/33% spell damage amplification.
    • 4 Heroes: 20%/28%/36%/44% spell damage amplification.
    • 5 Heroes: 25%/35%/45%/55% spell damage amplification.

Shadow Poison icon.png
Deals damage in a line, and afflicts enemy units with a poison effect. The poison deals 1/2/4/8/16 times the stack damage based on the number of stacks on the target, up to 5 stacks. Additional stacks cause 50 damage each. This deferred damage is dealt when Shadow Poison's duration is expired, or the Release sub-ability is used.
Cast Animation: 0.25+0
Cast Range: 1500
Travel Distance: 1500
Effect Radius: 200
Initial Damage: 26/34/42/50 (Talent 29.9/39.1/48.3/57.5)
Stacks to Multiply: 5
Multiplied Stack Damage: 24/36/48/60 (Talent 27.6/41.4/55.2/69)
Non-Multiplied Stack Damage: 50 (Talent 57.5)
Stack Duration: 10
Cooldown: 2.5 (Talent 1.25)
Mana: 45
Does not pierce spell immunity. Attempts to deal damage if enemy turns spell immune before the poison is released.
Buff modifier_projectile_vision: Undispellable. Persists death.
Debuff modifier_shadow_demon_shadow_poison: Dispellable with death only.
Ability Draft Notes
Ability Draft Notes:
Shadow Poison does not come with the Shadow Poison Release sub-ability. Instead, the ability utilizes Autocast. If enemies are debuffed, autocast is toggled on automatically. If the player then toggles it off, the poison gets released, triggering the damage.
The ever growing influence of the Shadow Demon can pollute the most valiant and pure of heroes.


  • Shadow Poison travels at a speed of 1000 and always travels the full distance, which takes 1.5 seconds.
  • The projectile provides 350 radius non-lingering flying vision around the poison cloud as it travels.
    • Provides 300 radius flying vision around each enemy unit it hits, and also upon reaching the maximum travel distance. This vision lingers for 3.5 seconds.
  • With the travel distance and effect radius, it can hit units up to 1700 range away.
  • Deals the initial damage instantly and adds 1 stack to all enemy units within 200 radius of it on each cast.
    • The poison first applies the debuff or adds a stack to an existing debuff, then deals the initial damage.
    • Successive hits on the same unit fully refresh the whole stack's duration.
  • The first 5 stacks get their damage multiplied by 1/2/4/8/16 depending on the amount of stacks.
    • Every following stack adds 50 (Talent 57.5) damage on top of that, so the damage starts growing linearly after the 5th stack.
    • Therefore, the poison's max potency is reached at the 5th stack.
    • The damage difference between applying 2 separate stacks of five and 1 stack of ten (excluding the initial damage) is 134/326/518/710 (Talent 154.1/374.9/595.7/816.5).
    • For how much damage each stack of Shadow Poison deals on each level up to the 10th stack, with the Shadow Poison damage increasing Talent talent (before reductions), please refer to the chart below.
  • Casting Shadow Poison Release or losing the Shadow Poison debuff in any way causes the damage to be dealt.
  • The current number of stacks is visible to Shadow Demon and his allies above the affected units. Enemies cannot see it.
    • This number is visually capped at 19, however, the poison has no stack limit and can be stacked infinitely.
    • The current number of stacks is also shown on the debuff icon, which is visible to everyone.

Aghanim's Shard upgrade: Allows Demonic Purge to be cast on allies, continuously dispelling them and healing for its damage values. Does not slow allies.
Debuff modifier_shadow_demon_purge_slow: Dispellable with death only.
Once Shadow Demon no longer has any need for his collected cultist, he releases it from its subservience - and its life.


  • Applies a basic dispel on the target upon cast and over its entire duration. The damage/heal is applied after the end of the duration.
    • Recasting onto the same target removes the modifier from a previous cast, triggering the damage/heal, and then applies a new instance.
  • Can be cast on invulnerable units, applying the initial dispel and the debuff if the invulnerability can be dispelled.
    • However, if the target is an enemy and if the invulnerability cannot be dispelled, only the dispel is applied, and the debuff is not.
  • Fully affects the target under the effect of the most recent Disruption cast by Shadow Demon.
  • The slow starts at 100% decreases over time to 20%. Hit units regain 0.381% of their movement speed on each server tick.
    • This translates to 11.43% movement speed regained per second.
  • The damage/heal is bound to the modifier, and applied whenever it is removed in any way.
    • It starts at 0 and increases by 1.43/1.9/2.38 (Talent 2.38/2.86/3.33) for each server tick affected, reaching the max values in 7 seconds.
  • With Aghanim's Scepter icon.png Aghanim's Scepter, applies Break on the target as well.
    • The break stops affecting the target before it deals its damage.
    • Acquiring Aghanim's Scepter instantly grants 2 extra charges. This only happens once, so re-acquiring it does not grant another 2 charges.
  • With Aghanim's Shard icon.png Aghanim's Shard, if the target is an ally, it can place the modifier on them even while invulnerable.
    • Does not apply movement speed slow or Break to allied units.
    • ↓↓ Double-tapping automatically targets self.

Complexity: ★★☆
Playstyle: Conspiring to gain power in material plane, the Shadow Demon patiently amassed himself a cult of followers. An entity of malevolent corruption, he spreads Shadow Poison to pollute the pure, compounding its effects with Soul Catcher. Heroes sent into the void of Disruption are temporarily hidden, but return with two illusions under his command. A Demonic Purge strips unneeded servants of every enchantment, effectively relieving them of their duties—and their lives.





  • In Dota, Shadow Demon's hero name was Eredar. This was removed in his transition to Dota 2 to avoid copyright issues with Blizzard as the Eredar are a race of magic wielders from the Warcraft universe.[1]
  • Shadow Demon's fun/alternate name was "Giblet", innards of birds that are used in cooking.
