Nortrom, the Silencer, is a ranged intelligence hero who can be played as a support, carry, or initiator. He is one of the few intelligence heroes that truly benefit from intelligence items and is effective against heroes that rely mostly on spells, as he can silence them while stealing their intelligence and adding it to his own. He is a notorious anti-caster hero who can disrupt the magical abilities of his enemies and cripple spellcasters throughout the game. Arcane Curse slows and causes enemies to lose health for a set duration, but increases with each spell the enemy casts, forcing them to either wait and cast no spell until it expires, or cast spells and prolong the debuff and thus take more damage. Last Word places a curse on Nortrom's target that damages and silences for a long duration if the target casts a spell. If the target does not cast a spell before the curse duration ends the effects are the same. Glaives of Wisdom is an active attack modifier that deals a percentage of Nortrom's intelligence as pure damage. Nortrom's ultimate, Global Silence, silences all enemy units on the map for a few seconds. A well-timed Global Silence can be used to save yourself or an ally, initiate a teamfight, or ruin the enemy's initiation.

Silencer has the unique innate ability, Intelligence Steal, which permanently steals the intelligence of enemy heroes that die near him or are directly killed by him and adds it to his own. This rewards his presence in teamfights, also making his glaives ever stronger as the battle goes on.


Silencer minimap icon.png Nortrom, the Silencer
▶️ "Enemies should be seen and not heard."
Part of the seventh and final generation of a carefully designed pedigree, Nortrom was bred by the ancient order of the Aeol Drias to be the greatest magic user the world had ever seen. He was the prophesied one, the culmination of two-hundred years of careful pairings, a war-mage who would bring glory to the order, and destruction to their sworn enemies, The Knights of the Fold. Raised with other young mages in a hidden cantonment among the hills of the Hazhadal barrens, the order's preceptors waited for Nortrom’s abilities to manifest. While the other students honed their talents with fire, or ice, or incantatory spells, Nortrom sat silent and talentless, unable to cast so much as a hex. As the day of final testing approached, he still hadn’t found his magic. In disgust, the preceptors berated him, while the children laughed. “You are no mage,” the head of the order declared. Still, Nortrom did not slink away. He entered the day of testing and faced down the young mages who had mocked him. And then his preceptors learned a valuable lesson: a lack of magic can be the greatest magic of all. Nortrom silenced the young mages one by one and defeated them in single combat, until he alone stood as champion of the Aeol Drias, in fulfillment of the prophecy.


Intelligence Steal
Cannot be used by illusions. Not disabled by Break.
Glaives of Wisdom icon.png
Enemy Heroes / Self
Silencer will permanently steal 2 (4 with Talent) intelligence from any enemy hero that dies within 925 range or is killed by the Silencer.
Steal Radius: 925
Stolen Intelligence: 2 (Talent 4)
Cannot be used by illusions. Illusions cannot steal intelligence.
Although the status buff is copied by illusions, the stolen intelligence is not copied.
Buff Int Steal: Undispellable.


  • This is an innate ability and does not need to be skilled. It is not bound to any ability, but to Silencer himself.
  • Stolen intelligence is directly removed from the enemy's base intelligence and added to Silencer's base intelligence.
  • Can only steal from base intelligence + intelligence gained from levels. Bonus intelligence cannot be stolen.
  • It does not matter how an enemy hero within the radius dies, Silencer always steals its intelligence.
  • Silencer also always steals intelligence when he deals the killing blow on an enemy hero, regardless of distance.
    • However, Silencer needs to be alive as the kill happens to steal the intelligence.
  • Cannot steal intelligence from illusions or hero clones.
    • When Silencer kills a Meepo minimap icon.png Meepo clone however, he does steal intelligence, since killing a Meepo clone also kills the main Meepo.
  • Cannot reduce enemy base intelligence below 1. Silencer also does not gain intelligence from heroes that are at 1 intelligence.
  • Enemy non-intelligence heroes effectively lose 24 (Talent 48) mana, 0.1 (Talent 0.2) mana regen and 0.14% (Talent 0.28%) spell damage.
    • Enemy intelligence heroes effectively lose 24 (Talent 48) mana, 0.1 (Talent 0.2) mana regen, 0.14% (Talent 0.28%) spell damage, and 2 (Talent 4) attack damage.
    • Vice versa, effectively increases Silencer's mana, mana regen amplification, spell damage, and attack damage by the same amount per stack.

Arcane Curse
Arcane Curse icon.png
Curses the target area, causing enemy heroes to take damage and slowing their movement speed. Anytime affected enemies cast a spell, the duration is increased.
Cast Animation: 0.3+0.37
Cast Range: 1000
Radius: 425
Damage per Second: 16/24/32/40 (Talent 46/54/62/70)
Move Speed Slow: 9%/12%/15%/18%
Base Duration: 6
Penalty Duration: 5
Cooldown: 20/18/16/14
Mana: 125/130/135/140
Does not pierce spell immunity. Slow persists and attempts to damage if debuff was placed before spell immunity and when not dispelled.
Debuff Curse Of The Silent: Dispellable with any dispel.
Nortrom's lack of incantations is less of a problem for him than it is for his adversaries.


  • Whenever an affected unit casts a spell, the duration is increased by 5. This effect has no stack limit.
  • If an affected unit gets silenced, the duration and the damage are paused until the silence expires.
    • However, the slow is not paused while silenced and still slows affected enemies.
  • Successive casts of Arcane Curse fully stack, always placing an independent debuff.
  • Deals damage in 1 second intervals, starting 1 second after the debuff is applied, resulting in 6 (+5 per penalty) instances.
  • Can deal up to 96/144/192/240 (+80/120/160/200 per penalty) (Talent 276/324/372/420, +230/270/310/350 per penalty) damage to a single unit (before reductions).
  • The sound effect played on every damage instance is only audible to the affected unit's player.

Glaives of Wisdom
Glaives of Wisdom icon.png
Silencer enchants his glaives with his wisdom, dealing additional damage based on his Intelligence.
Cast Range: 600 (Talent 725)
Intelligence as Damage: 25%/45%/65%/85% (Talent 45%/65%/85%/105%)
Damage Multiplier Against Silenced: 1 (Upgradable by Aghanim's Scepter. 2)
Cooldown: 0
Mana: 15
Aghanim's upgrade: Causes Glaives to pierce Spell Immunity and deal 100% more damage against silenced units.
Partially pierces spell immunity. Cannot be cast on spell immune enemies.
Can be cast on spell immune enemies when upgraded.
Although lacking in traditional incantations, Nortrom's pedigree of the Aeol Drias gives him uncanny wisdom, which he applies to physical combat.


  • Glaives of Wisdom deal their damage before the attack damage is applied, but still depend on the attack hitting the target.
  • Checks Silencer's intelligence as the projectile hits. Gaining/losing intelligence while the projectile is travelling does affect its damage.
  • When having Aghanim's Scepter icon.png Aghanim's Scepter, the glaives deal 50%/90%/130%/170% (Talent 90%/130%/170%/210%) of Silencer's intelligence as damage to silenced targets.

Last Word
Last Word icon.png
Enchants a target, causing them to be damaged and silenced if they cast a spell or if the enchantment timer expires.
Cast Animation: 0.3+0.47
Cast Range: 900
Initial Debuff Duration: 4
Damage: 75/150/225/300
Silence Duration: 3/4/5/6
Cooldown: 22/18/14/10
Mana: 115
Does not pierce spell immunity. Does not attempt to damage or silence if initial debuff was placed before spell immunity and when not dispelled. Silence persists if silence debuff was placed before spell immunity and when not dispelled.
Debuff Last Word: Dispellable with any dispel.
Debuff Last Word Disarm: Dispellable with any dispel.
Debuff Silence: Dispellable with any dispel.
Nortrom ensures that spells uttered by his opponents will be their last.


  • When the target casts a spell during the initial debuff, it gets damaged, then silenced, and then the cast spell goes off.
    • Since the spell counts as cast, the silence does not prevent it from happening. Although the silence happens first, the spell's effects are already queued up.
    • However death does stop the spell, meaning when the damage from Last Word is enough to kill the target, the cast spell does not go off.
    • This also means that damage negating spells like Refraction and spells that provide spell immunity do not block its damage.
  • Does not trigger on toggle abilities, active attack modifiers and the abilities listed here.
    • Triggers on channeling spells, but waits for the channeling to stop first.
    • Last Word does trigger on Phase Shift. However, it only applies its effects when Phase Shift is canceled by the player prematurely.
  • When the initial debuff expires, it still damages and silences the target.
  • The curse first applies the debuffs, then the damage.
  • Grants shared vision as long as the 4 second initial debuff is on.
  • The Last Word Disarm debuff, although no longer serving a purpose, is still applied and visible in the HUD.

Global Silence
Global Silence icon.png
No Target
Silencer stops all sound, preventing enemy heroes and units on the map from casting spells.
Cast Animation: 0.3+0.37
Radius: Global
Duration: 4.5/5.25/6 (Talent 6.5/7.25/8)
Cooldown: 130
Mana: 300/450/600
Debuff Global Silence: Dispellable with any dispel.
With a shock to the ground, all magic and sound pauses, and Nortrom fulfills his prophecy.


  • The sound effect of Global Silence which plays on each enemy's hero has the highest sound priority in the game.
    • This means it heavily tones down other game sounds for enemies, making it basically the only sound they can hear during the silence.

Recommended items[edit]

Starting items:

  • Tango icon.png Tango sustains Silencer's health in lane; as a support, he can also share the item with his team.
  • Healing Salve icon.png Healing Salve also restores health to Silencer or an ally.
  • Clarity icon.png Clarity allows Silencer to harass enemies with his abilities as needed.
  • Null Talisman icon.png Null Talisman provides damage for securing last hits and denies.

Early game:

  • Magic Wand icon.png Magic Wand has all the benefits of Magic Stick, along with providing stats and greater charge storage. As Silencer is quite vulnerable to enemy attacks even as a carry, burst HP regen is always helpful.
  • Boots of Speed icon.png Boots of Speed help Silencer get close enough to use abilities, and potentially get kills or assists to enjoy Intelligence Steal.
  • Wind Lace icon.png Wind Lace also provides movement speed boost. Additionally, it can build into Eul's Scepter of Divinity or Drum of Endurance.
  • Town Portal Scroll icon.png Town Portal Scroll transports Silencer to fights in order to steal early intelligence.

Mid game:

  • Power Treads icon.png Power Treads provides Silencer with attack speed and appropriate attributes, particularly strength to give him more health. The ability to switch attributes can help with spell casting and outputting damage.
  • Hurricane Pike icon.png Hurricane Pike can be used on himself or a teammate as an escape mechanism or him to close the distance upon a fleeing enemy, or can be used to push an enemy out of position. Also, it improves his attack range and allowing him to finish off an opponent with four glaives at long range.
  • Orchid Malevolence icon.png Orchid Malevolence is a powerful item to build on a carry Silencer, synergizing with all of his spells. Orchid is the only item which gives a large amount of int, mana regeneration, attack speed, and attack damage in one spot, and they're all things Silencer needs if he wants to be an effective carry.
    • Arcane Curse's duration pauses when silenced, so a third source of silences increases the effectiveness of this spell, and increases the likelihood of being able to apply a second curse, before the first wears off.
    • Glaives of Wisdom get more damage and more attack speed, plus Orchid's active will amplify all the damage done during its duration. Additionally, in combination with Aghanim's Scepter icon.png Aghanim's Scepter, this item increases the length of time Nortrom can gain the bonus damage to silenced targets.
    • Last word's biggest weakness is the 4 second delay before damage and silence is inflicted, allowing ganked targets to cast an escape spell. By using Soul Burn, then Last word, the delay duration becomes a benefit, as it provides True Sight over the target for the full duration, and continues into a total of 11 seconds of silence without using Silencer's ultimate.
  • Blink Dagger icon.png Blink Dagger is a powerful mobility tool, no matter what role Silencer is played in. As a support he can easily position himself to cast his disables on the enemy, as well as use it to evade enemy ganks. As a carry, it gives him strong positioning, allowing him to move quickly into a fight to attack after disabling the enemy with his ultimate. Or to simply blink in to steal intelligence from dying enemy heroes.

Late game:

  • Bloodthorn icon.png Bloodthorn, upgraded from Orchid Malevolence, provides additional critical strike and True Strike to counter evasion and bring down even the tankiest heroes.
  • Scythe of Vyse icon.png Scythe of Vyse provides a strong disable. It also gives intelligence and strength, as well as powerful mana regeneration to sustain his abilities.
  • Black King Bar icon.png Black King Bar greatly increases Silencer's survivability with strength and spell immunity so he can continue to output damage without worrying about enemy disables.
  • Aghanim's Scepter icon.png Aghanim's Scepter improves Glaives of Wisdom, allowing him to deal his full damage potential even against spell immune targets, as well as doubling the pure damage of his Glaives when he strikes silenced targets. The item itself also grants Silencer many beneficial attributes across the board, giving him more survivability overall.

Situational items:

  • Drum of Endurance icon.png Drum of Endurance suits an offensive Silencer in the early game, increasing the power of pushes with attack speed and improving his ability to chase enemies with movement speed.
  • Glimmer Cape icon.png Glimmer Cape, a support item, grants invisibility and magic resistance to Silencer and allies so they can escape.
  • Eul's Scepter of Divinity icon.png Eul's Scepter of Divinity increases movement speed and mana regeneration so Silencer can make plays on the map. The active Cyclone can disable enemies, remove debuffs from yourself, and make yourself temporarily invulnerable.
  • Rod of Atos icon.png Rod of Atos provides both intelligence and strength, as well as a root to catch enemies out of position, or to hold them in place so Silencer can retreat.
  • Shiva's Guard icon.png Shiva's Guard increases Silencer's survivability against physical damage while also granting him more intelligence to fuel his abilities and attacks, making it a well-rounded item. The slow can also help chase down fleeing enemies more easily.
  • Nullifier icon.png Nullifier synergizes well with silence so enemies cannot use abilities or items, while being slow every time an attack land on them.
  • Refresher Orb icon.png Refresher Orb, an ultimate late game item, enables Silencer to inflict a 12 seconds silence at highest level that pierces spell immunity and invulnerability, shutting down enemy heroes who rely on using abilities in team fights. It also refreshes items so he can use Black King Bar or Bloodthorn a second time, improving survivability and damage output.

Complexity: ★★☆
Playstyle: Two hundred years of selective breeding had produced Nortrom, the prophesied war-mage that would bring glory to the order of Aeol Drias. Therefore, disgust and disappointment followed when it was found that the boy could cast not even a hex. Yet, on the day of final testing, Nortrom would have the Last Word. His arranged opponents fell under an Arcane Curse, draining their health with each incantation made. Then, there was Global Silence. Not a gasp or whisper escaped their lips as Nortrom finished off each challenger with his multipronged Glaives of Wisdom. At that moment, it became clear to all watching: The absence of magic can be the greatest magic of all.





  • Unlike most heroes, Silencer's attack projectiles actually use the model of his equipped cosmetic weapon.
  • Like Death Prophet minimap icon.png Death Prophet, Omniknight minimap icon.png Omniknight and Io minimap icon.png Io, Silencer received a color palette change, changing his model and icons, having his former red armor replaced with violet.
    • Before his palette change, newer players would occasionally mistake Silencer for Dragon Knight minimap icon.png Dragon Knight, and he would sometimes be referred to as "The other Dragon Knight". Even after the palette swap, some older players may refer to him as "Purple Dragon Knight".
  • Silencer's spell sound effects are based on some of his voice lines. Arcane Curse debuff sounds is based on "▶️ Curse you!", Last Word is based on one of his laughing lines and Global Silence is based on ▶️ this.
  • Chen minimap icon.png Chen is a member of the Knights of the Fold which would make him an enemy to Silencer based on Silencer's background. Despite this, there is no dialogue between the two heroes.
