Steps in and out of the mortal plane to strike his foes.
Privy to secrets that would shatter a mortal mind, Inai emerges from the Hidden Temple 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 Resonant Pulses, he shrouds himself in the essence of the aether, a volatile energy that slays the weak and nullifies the attacks of the mighty. A tear in reality is observed as the Void Spirit Astral Steps through his enemies, leaving a trail of ruin in his path.

Void Spirit minimap iconInai, the Void Spirit
▶️ "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.
VS, Inai


Aether Remnant icon
Vector targeted. Void Spirit dispatches a remnant to the target location. The remnant stands watch over the region, facing the direction of his vector. When a unit crosses its gaze, the remnant pulls it in and damages it.

Void Spirit Aether Remnant area

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

  • 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, provided at all times around the remnant.
    • Together with the remnant's own vision, the total vision area has a length of 925, and a width of 450.
    • TALENT
      The Remnant True Sight Talent talent does not update exisiting Aether Remnants.
  • After the activation delay, the remnant searches for enemies within a path in front of it.
    • The search path has a length of 450 (Upgradable by Aghanim's Shard. 600) and width of 130.
    • When multiple enemies are within the area, it grabs the one furthest away closest to the center line.
    • Treats illusions, clones, summons and creep-heroes as heroes.
  • Applies a hypnotizing fear and provides True Sight over 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 330/312.5/300/290.63.
    • Grants the target unobstructed pathing, so they can move through cliffs, trees, and other units while walking towards the remnant.
  • For creeps, the remnant applies the damage right after the activation delay. Although the fear is applied, it is not noticeable.
    • The remnant now does not disappear when affecting creeps but still disappears once affecting enemy heroes.
  • 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, the pull debuff, then the damage debuff on creeps.
  • Destroys trees within a 200 radius around the target at the end of the fear.
  • For creeps, the remnant now also applies a 1-second debuff on enemy creeps within the area.
    • The debuff deals one damage instance immediately upon application on enemy creeps without the debuff.
    • The debuff neither stacks nor refreshes itself, it is reapplied on valid enemy creeps once its previous debuff duration ends.
      • This results in a maximum of 20 damage instances when standing within the area for the full duration.
    • One instance of the debuff can deal up to 21/36/51/66 (Talent 36/51/66/81) damage (before reductions).
      • Can deal up to a total of 420/720/1020/1320 (Talent 720/1020/1320/1620) damage to a single unit for the entire duration (before reductions).

Dissimilate icon
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.

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

Talent Dissimilate's portal formation.

  • Creates 7 (Talent 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 6 are adapted to it, with 60° angles between them, forming a hexagon.
    • TALENT
      With the outer ring Talent talent, the last 6 portals are placed in line behind the portals of the first ring.
      • These last portals are 1040 range away from the center portal and are placed using the same angles as the portals of the first ring.
  • Void Spirit can decide at which portal to reappear, by issuing a move order (Keyboard White Mouse Right 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 also selects the nearest portal to the enemy.
    • 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 grant phased movement, Void Spirit can still block other units during Dissimilate.
  • Does not disjoint projectiles upon teleporting.
    With the Dissimlate roots Talent talent, the damage and the 2-second root is dealt around the selected portal upon re-appearing.
    • Dissimilate first apply the damage, then the root.

Resonant Pulse icon
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.

Modifiers [?]
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 toward Void Spirit.
    • These projectiles travel at a speed of 900 and cannot be disjointed.
    • Once the projectiles reach Void Spirit, they increase the Physical Damage Barrier physical damage barrier by 40/60/80/100.
    • While active, if the base value 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 upon death stops the ring.
  • Grants Void Spirit a Physical Damage Barrier physical damage barrier that absorbs physical attack damage values, causing several on-damage effects to not trigger within its capacity.
    • Does not absorb spell damage of any damage types.
    • Stacks additively with the same damage-type barrier sources, and independently with other damage-type barrier sources.
    • Has a higher priority than universal damage barriers in the group of damage barriers.
    • However, when combined with other higher-priority damage-negating sources (e.g. Refraction icon Refraction), Resonant Pulse does not absorb any damage until the damage-negation sources expire.
  • Can grant up the following damage barrier capacity per hit hero:
    • 1x Hero: 80/140/200/260
    • 2x Hero: 120/200/280/360
    • 3x Hero: 160/260/360/460
    • 4x Hero: 200/320/440/560
    • 5x Hero: 240/380/520/660
  • Resonance Pulse first applies the damage, then the silence debuff.
    • Goes on a 0.25-second cooldown when cast to prevent accidental double-casts.
    • Acquiring Aghanim's Scepter icon Aghanim's Scepter instantly grants 1 extra charges. This only happens once, re-acquiring it does not grant another 1 charge.

Astral Step
Astral Step icon
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 seconds and then detonates.

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, the debuff, then the debuff damage.
  • Causes Void Spirit to perform an instant attack on every enemy unit along the path.
    • Fully affect Animal Courier Radiant minimap icon Couriers.
    • These instant attacks can proc any attack modifiers and on-hit effects normally, except for cleave. They have True Strike, and completely ignore disarms.
    • TALENT
      The critical strike Talent talent adds an ensured 140% critical strike to the instant attack as well.
      • If two sources of critical strike proc at the same time, the higher crit multiplier has 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.

Recommended Items[]

Starting items:

  • Tango icon Tango keeps Void Spirit alive in lane.
  • Enchanted Mango icon Enchanted Mango helps him spam his abilities on enemy heroes in laning phase.
  • Circlet icon Circlet grants bonuses to all attributes, giving Void Spirit a cost-efficient damage boost.
  • Iron Branch icon Iron Branch is very inexpensive and pads out Void Spirit's attributes and attack damage, and can be planted for more Tango regeneration.

Early game:

  • Phase Boots icon Phase Boots help Void Spirit chase enemies down and make him even more resilient against attacks.
  • Power Treads icon Power Treads are an alternative that grant additional health or mana as necessary and improve Void Spirit's attack speed for better physical damage.
  • Bottle icon Bottle is useful for sustaining Void Spirit in the mid lane and storing runes.
  • Bracer icon Bracer grants Void Spirit some extra attack damage through both raw bonuses and attributes while helping sustain him in lane.

Mid game:

  • Echo Sabre icon Echo Sabre gives useful bonuses to health and attack damage and helps him lock down enemies with Echo Strike. The mana regeneration supplements his spellcasting.
  • Aghanim's Scepter icon Aghanim's Scepter makes Void Spirit much more threatening and resilient in teamfights with its improvements to Resonant Pulse, and gives a respectable damage bonus to Universal heroes.
  • Manta Style icon Manta Style grants a decent amount of attributes and movement speed to make Void Spirit more adept at chasing and dealing damage. Mirror Image is also a versatile ability that allows him to better push and fight while letting him shrug off troublesome debuffs.

Late game:

  • Harpoon icon Harpoon builds from Echo Saber and boosts all attributes to improve Void Spirit's damage even further, and Draw Forth is an excellent tool for setting up Aether Remnant and keeping on top of enemies.
  • Eye of Skadi icon Eye of Skadi grants a substantial bonus to all of Void Spirit's stats and attack damage, and he can easily spread Cold Attack to multiple enemies with Astral Step.

Situational items:

  • Black King Bar icon Black King Bar can be used to protect against enemy disables if the silence from Aghanim's Scepter-upgraded Resonant Pulse is not enough; it can be used against enemy item-based disables that silence cannot stop.
  • Boots of Travel icon Boots of Travel provides Void Spirit relatively high movement speed and global presence across the map.
  • Orchid Malevolence icon 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 Bloodthorn if you have the gold.
  • Desolator icon Desolator improves the damage of Astral Step, which can also spread the armor debuff to multiple enemies.
  • Scythe of Vyse icon Scythe of Vyse grants Intelligence and mana regeneration to let Void Spirit use more abilities. The active Hex disables a dangerous target and sets up Dissimilate.
  • Kaya and Sange icon Kaya and Sange is a relatively inexpensive item that grants a wide variety of useful bonuses to damage, mana regeneration, and survivability.
  • Linken's Sphere icon Linken's Sphere saves Void Spirit from immediate, single targeted disables that can shut him down before he can use his abilities or Black King Bar, or pierce through debuff immunity. It also gives useful bonuses to attributes and regeneration.
  • Abyssal Blade icon Abyssal Blade gives a guaranteed stun which could be followed up with a Dissimilate or Aether Remnant for escape or damage. Astral Step further works with this item by potentially proccing the passive bash.
  • Refresher Orb icon Refresher Orb doubles Void Spirit's damage output, while further sharpening his mobility. Most useful in the late game.
  • Mage Slayer icon Mage Slayer protects against magic damage. Astral Step can debuff multiple enemies to debilitate nuke-heavy teams, and the mana regeneration is useful to sustain Void Spirit's spellcasting.
