Creates a copy of himself to split push.
A splintered fragment of the same primordial power as the Ancients themselves, Zet endeavors to end the disharmony among the warring factions through whatever means necessary. Solitary foes are thrown into a volatile state of Flux, ripping away their health over time. Distorting space to generate a Protective Field sheltering around allies, evading and attacking with greater efficiency. Zet summons Spark Fragments of its former self that circles in place, and seek out nearby foes. Is there one Arc Warden, or two? Armed with the original's items and abilities, the Self's Tempest Double duplicates each spell and every attack, bringing twice the chaos to any fight.

Arc Warden minimap iconZet, the Arc Warden
▶️ "It is not to aid the Ancients that this war is joined, but to destroy them both. This disunity must end."
Before the beginning of all, there existed a presence: a primordial mind, infinite, awesome, and set to inscrutable purpose. As the universe thundered into being, this mind was fragmented and scattered. Two among its greater fragments—who would come to be named Radiant and Dire--found themselves locked in vicious opposition, and began twisting all of creation to serve their conflict.

As war and cataclysm threatened the nascent cosmos, the will of a third fragment made itself known. Naming itself Zet, this intellect sought to resolve the disharmony and return all to perfect unity. Appalled by its kin's conflicting nature, Zet gathered the sum of its power. In a sudden flash, it overwhelmed its siblings, and fused the warring aspects into a stellar sphere before hurling them into the darkness to orbit a nondescript world. Harmony was restored, though only the barest fraction of Zet's strength remained. Setting its gaze on the prison, Zet chose to use its weakened power to serve as watchful warden until time's end. For uncounted aeons, this vigil stood.

Life flourished upon the world below, oblivious to the dangers imprisoned within the softly glowing moon, or of Zet's struggles to contain them. As the captives' eternal clash reverberated within, the surface of the prison shuddered, over time beginning to crack. Ultimately, Zet's depleted power proved insufficient to contain the breach, and at last the moon was shattered. The prison's ancient inhabitants had escaped to sow their conflict anew.

Flung to the farthest reaches by the prison's explosion, Zet was transformed by the dissonant energies of its former captives. No longer of single form and thought, its presence had become split among many—some lesser, some greater—each connected by a fleeting arc of consciousness. Struggling to suppress its own disunity, Zet sped toward the burgeoning conflict of its siblings, bending its fractured wills toward a singular conclusion: the aspects of the primordial mind must be made to reunite, or all must be destroyed lest the conflict spread further…
AW, Zet

  • While Flux' damage component is disabled, the particle effects on the target vanish, with only a red glow remaining on the unit, indicating the debuff is still there.
  • Multiple and/or successive casts on the same target fully stack, with all instances working independently from each other.
  • If the target has allies or neutral creeps within the 225 search radius, the ability temporarily stops damaging the target, until it is alone again.

Dire icon Dire side icon.

  • All effects, except the knockback, are provided by an aura. Its buff lingers for 0.1 seconds.
  • Grants the following bonuses to allies within the radius:
    • Flat attack speed bonus. However, the attack speed bonus of multiple Magnetic Fields does not stack.
    • 100% evasion bonus from incoming attacks outside of the radius.
      • Therefore, it does not evade attacks landing on allies when the source of the attack is within the field.
      • The evasion effect of multiple fields works independently.
      • This means when an ally is within the intersection of two Magnetic Field icon Magnetic Fields, attacks are evaded unless their source is also within the intersection.
  • Grants the following bonuses to allies within the radius:
    • Flat Ranged ranged attack range bonus.
      • Increases both Arc Warden's and the Tempest Double's attack range to Expression error: Unexpected < operator..
    • Grants flat base attack damage to attacks that are launched while the attacking hero is still within the radius.
      • Fully benefits illusions, and is affected by every percentage-based base attack damage increasing or reducing effects.
    • Both effects of the Tempest Component affect buildings and fully stack with themselves.
  • Despite its visual effects, the effective area is a cylinder, not a sphere.
  • Magnetic Field pushes every enemy within its 300 radius out of it upon cast.
    • The knockback is not a set distance. It pushes every enemy so that they are 350 range away from the center of the targeted area. So the min and max knockback distance are 50 — 350 respectively.
    • The knockback duration is always 0.3, so the speed varies between 1166.67 — 166.67, depending on the knockback distance.
    • Enemies are not disabled during the knockback, and are able to act freely, except moving during it.
    • Can push units over impassable terrain. Any trees the knocked back unit collides with gets destroyed.
  • All active instances now grant magic resistance bonus and immediately apply movement speed slow.
    • Increases both heroes' and buildings' magic resistance within its 300 effect radius.
    • The movement speed slow of multiple fields stack additively with each and with other sources of movement speed slow.
    • Can reduce affected enemies' movement speed by 60% by stacking two instances.
  • Stack multiplicatively with other Magic Resistance magic resistance sources.
    • Increases most heroes's magic resistance to 55% (Buildings 40%).
    • With the magic resistance bonus from this source, every 10 points of Intelligence attribute symbol intelligence further increases the total magic resistance by 0.6%. [?]
    The attack speed and attack damage increasing Talent talent immediately upgrade all current active instances, but not already placed buffs.

Spark Wraith (Radiant) icon
Arc Warden minimap icon Arc Warden:
Summons a Spark Wraith that slowly materializes and patrols a targeted area until an enemy comes within its range. Once a target has been found the wraith fuses with them, dealing magical damage and slowing the unit.

Spark Wraith (Dire) icon
Dire icon Dire side icon.

  • The Spark Wraith is fully visible to the enemy.
  • Once the activation delay is over, it checks for enemies, including neutral creeps, in 0.2-second intervals and launches itself toward the first registered enemy at a speed of 400.
    • Both the activation delay and second activation delay are independent of the wraith's duration.
    • The Spark Wraith has a 725 projectile speed instead.
  • If multiple enemies are within range after the delay, the closest enemy is targeted.
  • Damage values are based on the current level of the ability upon cast.
    • Leveling up Spark Wraith and chosing the damage increasing Talent talent does not update the damage of already placed or launched Spark Wraiths.
    • However, upgrade from Aghanim's Scepter icon Aghanim's Scepter immediately upgrades all placed and launched Spark Wraiths.
  • Provides 300 radius ground vision for its full duration. The vision does not linger.
  • The launched projectile also provides the same vision values, which linger for 3.34 seconds after reaching the target.
  • The wraith first applies the damage, then the debuff.
  • Despite the internal modifier name, Spark Wraith does not dispel the target.
  • Spark Wraiths create a secondary wraith immediately upon hitting the enemy.
    • These secondary wraiths have to go through a 2-second activation delay.
    • This effect only occurs once per Spark Wraith. Secondary Spark Wraiths cannot spawn new wraiths.

Tempest Double
Tempest Double icon
The Self
Briefly refocusing its fractured elements into a single form, the Arc Warden is able to create a perfect electrical duplication of itself. The duplicate can use all of Arc Warden's current items and special Tempest Double versions of his spells, except most consumables and items that drop on death. The duplicate has separate item and ability cooldowns. The Tempest Double loses its sense of self if he is too far away from Arc Warden and deals less attack damage.

Arc Warden Hud icons

Arc Warden's icons at the side of the screen. The currently selected unit is highlighted.

  • This ability is always inactive for the Tempest Double.
  • The Tempest Double minimap icon Tempest Double is a clone that always spawns at the selected location facing the same angle as Arc Warden, with 100% of Arc Warden's max health and mana.
  • On the first cast of Tempest Double, the double is actually summoned. On every following cast, it is just healed or revived.
    • The double gets dispelled as if it died, removing all modifiers which are removed by death. This means most modifiers that persist through death are not removed.
    • Its cooldowns are not refreshed upon getting re-summoned, so all cooldowns from the previous cast carry over.
    • Resummoning the Tempest Double does not disjoint projectiles.
  • Reduces the Tempest Double's main and bonus attack damage when the distance between Arc Warden and the Tempest Double exceeds 2000 distance.
    • Does not reduce outgoing conditional attack damage bonuses (e.g. Monkey King Bar icon Pierce or Silver Edge icon Shadow Walk).
    • Stacks additively with other total attack damage reduction sources.
    • The penalty is also applied when Arc Warden is dead unless it has Reincarnation sources.
    • A debuff appears on the Tempest Double whenever this penalty is active. The debuff is visible to allies only.
    • TALENT
      The no damage penalty distance Talent talent updates the current active instance and fully removes this restriction.
  • Arc Warden and the Tempest Double are represented by an icon with health and mana bars for each on the top left corner of the screen.
    • When a Zet is selected, its icon becomes brighter. When a Zet takes damage, its icon blinks red.
  • The Tempest Double is visually distinguishable from the original Zet for everyone.
    • On the minimap, allies see the unique Tempest Double minimap icon minimap icon, while enemies see Arc Warden minimap icon Arc Warden's default icon.
  • The double is a clone and therefore treated exactly like a hero by all abilities since it is not an illusion.
  • The double has a 180/240/300 Gold and a 180/240/300XP bounty. The gold is granted to the killing player, and the experience is distributed like any other experience.
    • However, if the double is killed by creeps or buildings, the gold gets distributed as well, just like hero kills do when not killed by players.
  • The Tempest Double does not passively gain any experience like heroes usually do, so it does not leech experience from its allies.
    • Any experience the Double would have gained (e.g. via Hand of Midas icon Transmute) is transferred to Arc Warden, even if the Tempest Double was dead at the time.
  • Other ultimate abilities are also always inactive if the Tempest Double attempts to copy them (e.g. in custom games).
  • Creates a Double based on Rubick minimap icon Rubick's model, that has all Rubick's basic abilities, with Spell Steal icon Spell Steal inactive, and without the other acquired abilities. Losing and reacquiring the ability allows Rubick to summon another Double from the previous steal.


Not disabled by Break.
Arc Warden Innate icon
The Self
The upheaval has attuned Arc Warden to the Ancients.

  • This is innate to Arc Warden and does not need to be learned.
  • When the hero's faction is the Radiant icon Radiant, the Zet will have its regular abilities, while its Tempest Double minimap icon Tempest Double will have the Tempest Component's ability traits and values as alternatives.
  • When the hero's faction is the Dire icon Dire, the Zet will have the Tempest Component's ability traits and values by default, while its Tempest Double will retain the original ability traits and values.

Item Interactions[]

Cooldown symbol Cooldown
  • The cooldown of an item (carried by the Tempest Double and Arc Warden) is bound to the item itself, and not to the unit holding the item.
  • Item abilities' cooldowns are not refreshed upon re-summon, all cooldowns from the previous cast carry over.
  • Giving Arc Warden another neutral item which already is on cooldown from another hero, will still be on cooldown in Arc Warden's inventory.
    • However, it will be usable by the Tempest Double upon summoning.
  • Items in Arc Warden's inventory that are still unusable due to the Backpack delay will be immediately available for the Tempest Double upon summon.
Aeon Disk icon
Black King Bar icon
  • These item abilities' cooldown works independently of the Tempest Double and it is not bound to Arc Warden's.
Refresher Orb icon
  • The Tempest Double has its own independent inventory and backpack, carrying the same item as the original Arc Warden does.
  • On each cast, its inventory gets updated and adapted to that of Arc Warden.
  • The Tempest Double can neither pick up nor drop any items. It cannot be given items by allies or Arc Warden directly either.
  • Shareable items are not sharable on the Tempest Double.
  • Sets the item's toggled status (e.g. Radiance icon Radiance) and Power Treads icon Power Treads's selected attribute stats) to match Arc Warden's as well.
  • Does not copy any muted items which Arc Warden has in its inventory (allied and enemy items alike).
Gem of True Sight icon
Divine Rapier icon
  • These items are not copied, due to their nature of dropping on death.
Hand of Midas icon
  • Using Hand of Midas icon Transmute grants the gold and experience to Arc Warden.
Desolator icon
  • Any Desolator icon Soul Stealer charges the Tempest Double gains are granted to Arc Warden’s Desolator instead.
Echo Sabre icon
Harpoon icon
Skull Basher icon
Abyssal Blade icon
  • The Tempest Double can use Abyssal Blade icon Overwhelm, but it cannot passively bash enemies.
Urn of Shadows icon
Spirit Vessel icon
  • The Tempest Double cannot gather its own charges but copies the main’s charges upon summon.
Helm of the Dominator icon
Helm of the Overlord icon
  • The Tempest Double's helm goes on cooldown upon cast, without dominating the targeted creep, if Arc Warden is not carrying the same helm in its inventory or backpack.
Power Treads icon
Vambrace icon
  • Sets the item to whichever Strength attribute symbol / Agility attribute symbol / Intelligence attribute symbol attribute Arc Warden had selected upon summoned.
  • Both items' Switch Attribute abilities function independently.
Neutral Items
Philosopher's Stone icon
  • The Tempest Double does not benefit from the item's bonus Gold Gold per minute trait.
Consumables and Charged-based Items
  • Does not copy Consumables (except for Town Portal Scroll icon Town Portal Scroll).
  • The Tempest Double cannot consume Moon Shard icon Moon Shard, but it copies the permanent buff off of the original Arc Warden.
  • Set all charges of charge-based items (e.g. Holy Locket icon Holy Locket) and item abilities (e.g. Desolator icon Soul Stealer) to match the charges on Arc Warden, no matter how many the Tempest Double had left the last time it was summoned.

Recommended Items[]

Starting items:

  • Tango icon Tango gives Arc Warden sustain in lane.
  • Faerie Fire icon Faerie Fire gives a bit of damage and can be a lifesaver.
  • Healing Salve icon Healing Salve restores large amount of health in the early game.
  • Iron Branch icon Iron Branch provides attribute bonuses and build into Magic Wand.
  • Magic Stick icon Magic Stick can be an alternative starting item if playing against casters.

Early game:

  • Boots of Speed icon Boots of Speed improves Arc Warden's mediocre movement speed and gives him some form of escape from enemies.
  • Magic Wand icon Magic Wand restores some health and mana, allowing Arc Warden to use his abilities and escape items like Hurricane Pike icon Hurricane Pike.
  • Hand of Midas icon Hand of Midas accelerates Arc Warden farming game. Keep track of its cooldown on Tempest Double to know when optimal times to use it are.

Mid game:

  • Boots of Travel icon Boots of Travel gives Arc Warden map wide presence for fighting, pushing, and farming.
  • Gleipnir icon Gleipnir gives decent stats and crowd control, a good alternative. It's ideal for early to mid game skirmishes, as well as late game teamfights. The major disadvantage of the item is being countered heavily by dispels and lack of attack speed, although the active bypasses Linken's Sphere icon Linken's Sphere.
  • Mjollnir icon Mjollnir buffs both yours and your Tempest Double's attack speed as well as punishing enemies who attack either.
  • Manta Style icon Manta Style is a great item for mid-game fights, as it's component - Yasha icon Yasha - is one of the most cost-efficient items for agility heroes, giving Arc Warden much needed agility and movement speed. The active dispels some negative effects, and four illusions from Tempest Double and Zet can wreak havoc. The double's and the original's Manta Style are independent from and do not replace each other. The illusions also benefit from Magnetic Field, making them more resistant to physical attacks and speeding up their attack speed.

Late game:

  • Hurricane Pike icon Hurricane Pike lets Arc Warden stay in the back with the increased attack range, and gives him an escape that, if used by Tempest Double as well, can effectively double the distance traveled.
  • Monkey King Bar icon Monkey King Bar helps tremendously to counter evasion and highly armored heroes, while dealing less to those with high magic resistance.
  • Nullifier icon Nullifier allows Arc Warden to dispel and slow down enemies so they cannot be protected by defensive items like Glimmer Cape icon Glimmer Cape or Force Staff icon Force Staff. 80 damage and 8 armor for low price can't be ignored, either. An ideal item both to kite melee rightclickers like Sven minimap icon Sven and prevent heroes like Drow Ranger minimap icon Drow Ranger or Zeus minimap icon Zeus from escaping.
  • Scythe of Vyse icon Scythe of Vyse boosts Arc Warden's mana and mana regeneration to use abilities liberally. The Tempest Double can use hex as well, doubling the disabling duration. Take care with chain disabling, as the enemy may use Black King Bar icon Black King Bar right after.

Situational items:

  • Blink Dagger icon Blink Dagger allows offensive Arc Warden and Tempest Double to approach enemy targets and unleash their abilities and items quickly.
  • Shadow Blade icon Shadow Blade provides attack speed and attack damage, as well as invisibility for Arc Warden to escape or initiate on enemies. It can upgrade to Silver Edge icon Silver Edge to apply break, suppressing both offensive and defensive passives.
  • Bloodthorn icon Bloodthorn boosts mana regeneration as well as damage output with attack speed, attack damage, and True Strike. The silence also prevents much of retaliation or escape from enemies. Black King Bar icon Black King Bar and other dispel items can counter this effect, so take caution.
  • Black King Bar icon Black King Bar counters most disables so Arc Warden can attack and use items. It can also be used to send in the double in fights and staying back in safety with the main Arc Warden. The Double can use Avatar, but its duration is independent of the main Arc Warden's Black King Bar.
  • Butterfly icon Butterfly turns Arc Warden into a heavy hitter. His primary attribute is agility, so he benefits a lot from its attributes. The Tempest Double has no attack damage penalties like most illusions do, since it is not an illusion, so it can greatly increase Arc Warden's overall damage output. Arc Warden's two damaging spells deal both magical damage and do not scale. A Butterfly helps him keep on doing damage to the enemy in the late game. The attack damage he gets from the item is also great for pushing and synergizes very well with Magnetic Field.
  • Daedalus icon Daedalus, like Butterfly, significantly increases your damage output, as Arc Warden can constantly deliver crits thanks to the enormous attack speed boost provided by Magnetic Field. Note that this passives doesn't work against buildings.
  • Divine Rapier icon Divine Rapier, although not as good as it used to be on the double, still packs a punch and goes well with Arc Warden's attack range and attack speed.

  • ▶️ You will just have to accept this, and move on.



  • Arc Warden was first teased on day 3 of the New Bloom 2015 update page, where he's frozen within a glacier. His head, a shoulder pad and hand are partially visible.
    • After being teased in the update that officially added Winter Wyvern to the game, he ended up being the next hero to be ported over from DotA1.
  • The line ▶️ "You will just have to accept this, and move on." is a reference to a Dota 2 based web cartoon "The Dota 2 Reporter", where it is a recurring gag for the characters to question the game's logic, only to be answered by this line.
  • The lines ▶️ "Doggedly." and ▶️ "Hounding." are references to Arc Warden's former appearance in DotA, where its model was that of a Gnoll, a canine-like creature from Warcraft. Its rivalry lines towards Lycan minimap icon Lycan, ▶️ "Inferior form." and ▶️ "Apex predator, you are not. ", are also a nudge to this.
  • A lot of Arc Warden's lore and responses reference the work of the psychiatrist Carl Gustav Jung.
    • Arc Warden's focal point of unification is based on the psychological concept of individuation. Put in simple terms, in Jungian Psychology, the concept of individuation is when the conscious ego combines with the unconscious shadow, creating "the Self". Arc Warden exclusively refers to itself as "The Self". Tempest Double icon Tempest Double's concept also references this, with Arc Warden representing the conscious ego, and the Tempest Double representing the unconscious shadow. As stated in the ability's lore, Arc Warden despises this ability, since it brings disharmony; Arc Warden can only be The Self if not split apart.
    • Some of Jung's work is also reflected in Arc Warden's abilities, like how Flux (Radiant) icon Flux is only harmful when the target is alone, i.e. not united with their allies, or how Magnetic Field (Radiant) icon Magnetic Field only works against enemies outside its area of effect. Spark Wraith (Radiant) icon Spark Wraith's ability description also states that it affects its target by "fusing" with them.
    • ▶️ "From the Primordial Consciousness all came. Return to it, all must." refers to the pyschological concept of the Collective Unconscious, which refers to the unconscious mind and shared mental concepts. This term was also coined by Carl Gustav Jung.
