Ezalor, the Keeper of the Light, is a ranged intelligence hero famous for his reputation as a one-man support team. Supporting his allies in need, and pushing unguarded lanes with ease, Ezalor is a very valuable ally for any team. Having a variety of useful abilities, he can channel a powerful globe of intense light that can heavily damage an army of enemy creeps in the lane, allowing for an easy push. He can also restore mana and reduce cooldown for himself and his allies as well as blind his enemies with an intense light that also damages and displaces them. His Ultimate hypnotizes enemies in an AoE periodically, allowing his allies to follow over with their attacks around this immensely powerful crowd control. Keeper of the Light requires patience, confidence, and selfless behavior to play him well, as he is played as a support instead of a killer caster like most Intelligence gankers. His set of abilities also requires good timing, reflexes, and knowledge to use well.


Keeper of the Light minimap icon.pngEzalor, the Keeper of the Light
▶️ "They say twas I who carried the first light into the universe. They might be right, I can't quite recall."
Upon a pale horse he rides, this spark of endless suns, this Keeper of the Light. Ezalor long ago escaped the Fundamental plane, separating from the other ancient forces to which he was bound within the great Primordial harmony. He is a power grown sentient in the dawn of the universe, and now rides forth in all planes at once, one step ahead of pursuing chaos, bearing his gift with him at the end of a radiant staff. His majestic truth lies hidden beneath the outward appearance of a slightly doddering old man who barely stays in the saddle. However, when faced with the challenge of chaos, or the forces of darkness, his primordial light bursts forth, and his full power is revealed, transforming him once again into a force to be reckoned with.

  • The wave travels at a speed of 1050, taking 1.48 (Talent 1.71) seconds to travel the full distance.
  • Can hit units up to 1925 (Talent 2175) range away (travel distance + radius).
  • The Damage and heal increase by 1 for every 0.01 seconds, starting as the 0.3 second cast time begins.
    • The damage/heal increasing talent does not alter this. The talent's bonus is added after the scaling damage is calculated.

    • The vision fields are spawned in 0.5 second intervals, starting 0.5 seconds after channeling start, resulting in up to 3/5/7/9 fields.
    • When the channeling gets canceled, it stops spawning vision fields. This does not affect the travel distance of the wave.
    • When fully channeled, all vision fields together reach up to 825/1125/1425/1725 range away with their vision.
  • The horses only spawn when the spell is channeled for the full 2/3/4/5 seconds and only have a visual purpose.

Restores mana to the target unit and reduces cooldowns of all abilities currently on cooldown by a fixed amount. Can be cast on enemy, placing a debuff that drains 4.5%/5%/5.5%/6% of current mana per 100 units moved.

In the same vein, Ezalor bestows his harmony among others.


  • Only reduces cooldowns of every non-ultimate ability, including passive abilities.
  • Checks the enemy target's current position once upon cast and then in 0.1 second intervals, resulting in 51 checks.
  • On each check, it compares the target's current position with its position on the last check and reduces its mana based on the distance between the positions.
  • Does not reduce mana when the distance between two positions is greater than 300. So a unit needs to move at more than 3000 speed, or blink a distance greater than 300 to not lose mana.
  • The sound effect upon losing mana is only audible to the target.

  • Only attacks from heroes (including clones, excluding illusions) can damage the wisp.

Complexity: ★★☆
Playstyle: What appears to be a frail old man on his steed is, in truth, a Fundamental, the Keeper of the Light. Ezalor's staff Illuminates the darkest corners, banishing evil from the realm. He replenishes his companions with Chakra Magic, while casting a Blinding Light over the land, causing attacks to miss. Heads turn to stare at a mysterious shimmering orb, unable to look away as the Keeper's allies encircle foes hypnotized by the flickering lights of the Will-O-Wisp.





  • Ezalor's design in Dota 2 makes several references to Gandalf, an iconic character from The Lord of the Rings book series.
    • His clothing is almost purely white, similar to Gandalf's attire.
    • Illuminate's wave animation are a group of stampeding white horses. This is similar to the spell Gandalf cast on the torrent of water, at the ford of Bruinen, in the first book, The Fellowship of the Ring. Additionally, it has similarities to his reinforcements at Helm's Deep during the second book, The Two Towers. This is also depicted in the splash art, with Ezalor taking Gandalf's place at the head of the charge.
    • The Mana Leak cast line ▶️ "You shall not cast!" is a reference to one of Gandalf's most famous quotes: "You shall not pass!"[1]
    • The unused Mana Leak cast line ▶️ "Run! Run, I say!" is a reference to another one of Gandalf's famous quotes: "Fly, you fools!"[2]
    • The respawn lines ▶️ "Ezalor... I think that's my name" is likely a reference to Gandalf "respawning" as The White: "Gandalf? ... Yes ... That was my name ... Gandalf the Grey."
    • One of Ezalor's cosmetic items, the Wise Cap of the First Light makes him look even more like Gandalf.
  • The lines ▶️ "Kundalini!" and ▶️ "The serpent of illumination stirs!" come, as well as the term "Chakra" are derived from Hinduism. Kundalini is described as a dormant inner strength, or "sleeping serpent waiting to be awakened".
  • Enigma minimap icon.png Enigma, Chaos Knight minimap icon.png Chaos Knight, Keeper of the Light minimap icon.png Keeper of the Light, and Io minimap icon.png Io together represent the four fundamental forces of the universe with Keeper of the Light representing the electromagnetic force, the force responsible for light.
    • Io's lore mentions "the great twin riders Dark and Light," referring to Chaos Knight (weak interaction) and Keeper of the Light (electromagnetism) uniting under the electroweak interaction.
  • The rivalry line ▶️ "And chaos fled!" may be a reference to an official bug that can occur when fighting the final boss of Final Fantasy, Chaos, as you can win the fight without damaging him (he simply just fled).
  • His rare line ▶️ "I'll tell thee everything I can, there's little to relate." and ▶️ "Very gladly will I drink your honor's noble health." are quotes of the poem by "Haddock's Eyes" by Lewis Carroll, a poem about a very odd old man.[3]
  • His rare line ▶️ "I'll forego green girdles and questing beasts, for all such knightly trifles pale before the light." is a reference to the book The Sword in the Stone.
