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 damage increases by 2.02/3.03/4.04/5.05 (Talent 3.84/4.85/5.86/6.87) for every 0.03 seconds, starting as the 0.3-second cast time begins.
    • This means it can deal a minimum of 20/30/40/51 (Talent 38/48/59/69) damage.

Recommended Items[]

Starting items:

  • Tango icon.png Tango provides health regeneration while laning, which mitigates harass damage by lane opponents. Keeper of the Light can share it with allies if needed.
  • Healing Salve icon.png Healing Salve also restores health early on to you and teammates.
  • Iron Branch icon.png Iron Branch gives some attributes, and can be used to build Magic Wand or Mekansm.
  • Observer Ward icon.png Observer Ward gives vision around the map, and helps Keeper of the Light get into a good position to use Illuminate.

Early game:

  • Tranquil Boots (Active) icon.png Tranquil Boots gives Keeper of the Light more movement speed for little expense. The passive regeneration keeps his health at full, allowing him to be self-sustaining as he can replenish his mana with Chakra Magic.

Mid game:

  • Force Staff icon.png Force Staff can be used for mobility, saving teammates, or forcibly displacing enemies, particularly effective when combined with and Blinding Light.
  • Glimmer Cape icon.png Glimmer Cape may save Keeper of the Light and allies with invisibility and magic resistance. Also, he can activate it before or during channeling of Illuminate and Town Portal Scroll.

  • Ghost Scepter icon.png Ghost Scepter grants immunity against physical damage so Keeper of the Light can survive against enemy carries.
  • Scythe of Vyse icon.png Scythe of Vyse provides a large boost to attributes and excellent mana regeneration, allowing Keeper of the Light to use Chakra Magic on teammates more frequently instead of on himself. The Hex it offers is very powerful on Keeper of the Light, as he otherwise lacks an instant hard disable.

Situational items:

  • Mekansm icon.png Mekansm synergizes well with Keeper of the Light's support abilities, as he can heal his teammates as well as restore their mana. The overall attributes and armor also provide Keeper of the Light with considerably more survivability, while Chakra Magic covers the item's high mana cost.
  • Rod of Atos icon.png Rod of Atos grants more survivability and a larger mana pool. Its root makes chasing or escaping from single enemies much easier due to its long cast range and low cooldown.
  • Eul's Scepter of Divinity icon.png Eul's Scepter of Divinity gives Keeper of the Light a sustainable mana pool and increased movement speed, allowing him to be much more active on the battlefield. The active ability dispels debuffs such as silences while making Keeper of the Light temporarily invulnerable, or disables an enemy long enough for Illuminate to charge up damage.
  • Solar Crest icon.png Solar Crest gives Keeper of the Light armor, attributes, and mana regeneration. As a ranged support, you have the ability to reduce an enemy's or Roshan's armor for your team to capitalize on, or give an ally more armor to extend their survivability.

  • Lotus Orb icon.png Lotus Orb improves Keeper of the Light's armor and regeneration. The basic dispel and active ability increase survivability of him and his allies by removing debuffs and may dissuade the enemies from using targeted abilities.
  • Aether Lens icon.png Aether Lens increases Keeper of the Light's cast range, letting him support allies from a safer distance away.
  • Aghanim's Scepter icon.png Aghanim's Scepter grants Will-O-Wisp ability that can be useful in teamfights.

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 weak nuclear force, the force responsible for the light of stars and suns, including the sentient sun Phoenix minimap icon.png Phoenix.
    • His Solar Bind and Mana Leak abilities reflect his theme of radioactive decay. As the name implies, it is the decay of an unstable atomic nucleus by radiation, the transmission of energy. Hence, the spell's ability to drain move speed or mana (energy) when an opponent moves (transmission).
    • Enigma's lines upon killing him further reinforces this when he says ▶️"Ezalor, your decay is now complete." and ▶️"Ezalor, the weak and infirm." which references radioactive decay and the weak force itself, respectively.
  • 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.
