Resonant Pulse

Inai, the Void Spirit, is a melee intelligence hero that relies on the element of surprise to blast apart foes with the power of the void. He plays like no other hero, relying on a wide variety of skills that allow him to put his enemies out of position while quickly jumping in and out of combat. Using his Aether Remnants, Inai can start and end any fight in seconds by forcing enemies to attack remnants of himself that guard from all angles. The void is both sword and shield for Void Spirit, whether he takes a quick repose in the aether to teleport to an area of his choice with explosive force, or shields himself in volatile energy that slays the weak and nullifies the attacks of the mighty. Should anything manage to survive the Void Spirit's onslaught, he calls upon his mastery of the ultimate Astral Step technique, dashing through space and time to attack and mark enemies for death not once, but twice.

▶️ "Friend or foe, in the wake of the confluence, you will follow where I lead."
Not even the other spirits claim to understand the mind and machinations of the eldest amongst them, Inai the Void Spirit. Privy to secrets that would shatter a mortal mind, the Void Spirit observes the workings of the universe from an unknowable vantage, choosing to let carefully groomed servants do his bidding -- only emerging from his Hidden Temple into the material plane when he deems that he alone can steer the course of reality along its proper path.

With an expansive perspective on existence, Inai is focused intently on a point in time beyond which he cannot see, when the fabrics of multiple realities are fated to collide. Now he steps from the aether to personally resolve the battle of the Ancients and prepare his allies for what he views as a greater conflict to come.


Aether Remnant's search area (red) and vision area (yellow)

Inai exists far beyond the scope of a single point in space and time.


  • The remnant moves towards the targeted point at a speed of 900.
  • Upon reaching the targeted point, the remnant faces towards the targeted direction, and then remains inactive for 0.4 seconds.
  • After the activation delay, the remnant provides flying vision in front of it.
    • The vision is provided by 2 vision cells, each with a radius of 200.
    • The first vision cell is positioned 225 range in front of the remnant, the second one 450 range in front of it.
    • The remnant itself also has 250 radius ground vision and 475 radius True Sight. This is the dummy's vision, and is provided at all times around the remnant.
    • The Remnant True Sight Talent talent does not update already placed Aether Remnants.
    • Together with the remnant's own vision, the total vision area has a length of 925, and a width of 450.
  • After the activation delay, the remnant searches for enemies within a path in front of it.
    • The search path has a length of 450 and width of 130.
    • When multiple enemies are within the area, it grabs the one furthest away closest to the center line.
  • Hypnotizes the target, pulling it towards the remnant, and prevents it from acting.
    • Sets the target's movement speed to 44%/50%/56%/62% of the distance between Remnant and the target.
    • If the target is too close, it stops moving once within 100 range of the remnant.
    • When cast at maximum cast range, this results in a speed of 235.71/234.38/233.33/232.5.
  • The speed is set once upon cast. If the target gets moved or teleported, the speed does not adapt.
  • Aether Remnant first applies the damage, then the pull debuff.
  • Destroys trees within a 200 radius around the target at the end of the hypnosis.

Upgradable by Aghanim's Shard. Dissimilate's portal formation.

Dissimilate icon.png
No Target
Self / Enemies
Void Spirit temporarily fades into the aether, creating a number of portals through which he can reassemble himself. Upon exiting a portal, he damages all enemies in the area.

Portals Radius: 275
First Ring Radius: 520
Number of First Ring Portals: 6
Damage: 100/180/260/340 (With Aghanim's Shard 275/355/435/515)

Inai much prefers to observe our plane free from the confines of corporeal form.


  • Creates 7 (Upgradable by Aghanim's Shard. 13) portals, with one of them being at the cast location.
    • The following 6 portals form a ring around the center portal, with their center being 520 range far away from it.
    • One portal is created in front of Void Spirit, while the other 5 are adapted to it, with 60° angles between them, forming a hexagon.
    • With Aghanim's Shard icon.png Aghanim's Shard, the last 6 portals are placed in line behind the portals of the first ring.
      • These last portals are 520 range away from the center portal and are placed using the same angles as for the portals of the first ring.
  • Void Spirit can decide at which portal to reappear, by issuing a move order (Keyboard White Mouse Right.png Right Click or M).
    • Directly clicking on the portals is not required, a directional order is enough. The closest portal to the right-clicked location gets selected.
    • Attack orders behave like move orders during disarms, so right-clicking an enemy selects the closest portal to the enemy as well.
    • Void Spirit can change the selected portals as many times as he wants while hidden.
    • A selected portal is highlighted for Void Spirit and his allies. For enemies, all portals look the same.
  • Does not provide phased movement, so Void Spirit can still block other units during Dissimilate.
  • Does not disjoint projectiles upon teleporting.
  • The damage and the 1.75 seconds stun is dealt around the selected portal upon re-appearing.
    • Dissimilate first applies the damage, then the stun.

Resonant Pulse icon.png
No Target
Self / Enemies
Void Spirit wraps himself in a protective shield that absorbs physical damage and emits a single damaging pulse around him. The shield gains increased damage absorption for each enemy hero the pulse hits.

Inai never hesitates to shroud himself in the essence of his true self when forced to interact with the mortal plane.


  • Interrupts Void Spirit's channeling abilities upon cast.
  • Resonant Pulse is a thin ring expanding outwards at a speed of 1200, taking 0.42 seconds to reach maximum range and dissipate.
    • It can be avoided by teleporting towards Void Spirit over the ring shortly after cast.
  • Enemy units hit by the ring are damaged, and release a projectile towards Void Spirit.
    • These projectiles travel at a speed of 900 and cannot be disjointed.
    • Once the projectiles reach Void Spirit, they increase the shield's capacity by 30/45/60/70.
    • While active, if the base shield is depleted before these projectiles reach, they create a new shield, with their own capacity.
  • The pulse is bound to a modifier. Multiple instances of the modifier stack, so that each cast releases a ring.
    • The modifier is lost upon dying, therefore dying stops the ring.
  • The shield only works against physical attack damage. Other damage types and spell damage of any kind is not blocked.
    • Resonant Pulse fully negates, causing several on-damage effects to not trigger.
    • Blocks damage after armor and damage block reduce it, but before any other reductions.
    • Multiple instances of the shield do not stack, recasting refreshes the duration and resets the absorption value.
  • This is how much physical attack damage Resonant Pulse can block after hitting a certain amount of heroes:
    • 1 Hero: 70/125/180/230 damage.
    • 2 Heroes: 100/170/240/300 damage.
    • 3 Heroes: 130/215/300/370 damage.
    • 4 Heroes: 160/260/360/440 damage.
    • 5 Heroes: 190/305/420/510 damage.
  • With Aghanim's Scepter icon.png Aghanim's Scepter, Resonance Pulse first applies the damage, then the silence debuff.
    • Goes on a 0.25-second cooldown when cast to prevent accidental double-casts.

Astral Step
Astral Step icon.png
Enemies / Self
Void Spirit tears a rift through the astral plane to appear at the target location, attacking all enemies along the path. This attack inflicts a void mark that slows for 2 seconds and then detonates.
Cast Animation: 0.2+0

Min Distance: 200
Max Distance: 700/850/1000

Buff modifier_void_spirit_astral_step_caster: Dispellable with death only.
Debuff modifier_void_spirit_astral_step_debuff: Dispellable with any dispel.
A small step for Inai creates great devastation on the mortal plane.


  • Void Spirit is teleported instantly towards the targeted point upon cast.
  • Does not disjoint projectiles upon teleporting.
  • Astral Step first applies the instant attack, then the debuff.
  • Causes Void Spirit to perform an instant attack on every enemy unit along the path.
    • These instant attacks can proc any attack modifiers and on-hit effects normally, except for cleave. They have True Strike, and completely ignore disarms.
    • With the level 25 Talent talent, the instant attacks apply an ensured 160% damage critical strike as well, crits with a lower value have no effect if they proc, since the higher crit value takes priority.
  • All hit enemies also receive the movement speed slow debuff. This debuff deals damage upon losing it.
    • This means dispelling it causes the damage to happen earlier.
    • Multiple instances of the debuff fully stack and work independently from each other.

Mid game:

  • Eul's Scepter of Divinity icon.png Eul's Scepter of Divinity is a good choice against mobile targets or heroes with silences that can shut you down. Not only does it provide an escape against these heroes, but it can also be used as a setup for Aether Remnant.
  • Orchid Malevolence icon.png Orchid Malevolence grants you a silence and damage amplification to use with your abilities on a single target, also granting large amounts of mana regen to spam your abilities. This can be easily upgraded later into a Bloodthorn icon.png Bloodthorn if you have the gold.

Late game:

  • Black King Bar icon.png Black King Bar is a good defensive item for him as he can be shut down with silences and magical bursts.
  • Aghanim's Scepter icon.png Aghanim's Scepter turns Resonant Pulse into an area silence, giving Void Spirit a strong initiation tool.
  • Shiva's Guard icon.png Shiva's Guard is a good item for you and your team. The armor synergises with Resonant Pulse (armor is calculated before the shield HP). It also gives great stats and you can spread the slow to everyone on the enemy team with your high mobility.

Situational items:

  • Aghanim's Shard icon.png Aghanim's Shard gives both increased mobility and increased damage with its boosts to Dissimilate.
  • Veil of Discord icon.png Veil of Discord augments Void Spirit's area of effect spell damage, letting him nuke down enemy teams faster.

  • Scythe of Vyse icon.png Scythe of Vyse grants attributes, intelligence, and mana regeneration to let Void Spirit use more abilities. The active Hex disables a dangerous target and sets up Dissimilate.
  • Kaya icon.png Kaya gives Void Spirit increased attack and spell damage, along with reduced mana costs to sustain his spellcasting.
  • Bloodstone icon.png Bloodstone is a great option to upgrade your Kaya icon.png Kaya. Not only is it item-slot efficient, but it also allows you to spam your spells even more, as well as give you even more spell damage.

  • Abyssal Blade icon.png Abyssal Blade is a good item as you not only gain a damage block, but a guaranteed stun which could be followed up with a Dissimilate for escape or damage. Your Astral Step further works with this item by potentially proccing the passive bash.
  • Maelstrom icon.png Maelstrom is a great item for farming and pushing and also increases your damage in fights with Astral Step.
  • Radiance (Active) icon.png Radiance continues to do damage while Void Spirit is using Dissimilate. The damage emanates from Void Spirit's original position before using Dissimilate.
  • Item needed.

Complexity: ★★☆
Playstyle: From the Hidden Temple, Inai steps into the material world to perform tasks that change the trajectory of the world. Dissimilating and reappearing in random portals, the Void Spirit leaves behind glowing Aether Remnants that pull enemies into their destructive embrace. Sending out a Resonant Pulse, he shrouds himself in the essence of the void, absorbing incoming attacks. A tear in reality is observed as the Void Spirit Astral Steps through his enemies, leaving a trail of ruin in his path.
