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; and manipulate the mana around him, restoring mana for himself and his allies or draining the mana of his enemy. His Ultimate allows him to gain his full power, giving Ezalor access to 2 sub-abilities and an improved existing ability, giving him six different abilities in total. 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 wide set of abilities also requires good timing, reflexes, and knowledge to use well.


Keeper of the Light minimap icon.png Ezalor, the Keeper of the Light
Play "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.

Recommended items[edit]

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.
  • Animal Courier (Radiant) icon.png Animal Courier should always be purchased by a support at the start of the game.
  • 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:

  • Boots of Speed icon.png Boots of Speed increase Keeper of the Light's mobility, which can be crucial for getting into position to cast his spells.
  • Magic Wand icon.png Magic Wand increases Keeper of the Light's attributes for cheap, and provides burst health and mana restoration, increasing overall survivability.

Mid 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.
  • 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.
  • Force Staff icon.png Force Staff can be used for mobility, saving teammates, or forcibly dispositioning enemies, particularly effective when combined with and Blinding Light.

Late game:

  • 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:

  • 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.
  • Veil of Discord icon.png Veil of Discord gives Keeper of the Light attributes and armor, making him more survivable. Its active ability also gives him powerful teamfight contribution, especially when coupling with Illuminate, and is a good item to buy if your team can capitalize on their magic nukes.
  • Solar Crest icon.png Solar Crest gives Keeper of the Light armor, evasion, 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.
  • 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 extremely long cast range and low cooldown.
  • 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.
  • Pipe of Insight icon.png Pipe of Insight resists and shields Keeper of the Light and teammates against magical damage so they can survive and contribute to teamfights.
  • Shiva's Guard icon.png Shiva's Guard gives Keeper of the Light more physical survivability, a larger mana pool, and better teamfight contribution. The intelligence and armor allow Keeper of the Light to participate more in fights, while the attack speed aura and active freeze aura slows enemies' attempts to deal damage with their physical attacks and slows their movement speed with an additional damage nuke.
  • Octarine Core icon.png Octarine Core helps Keeper of the Light use abilities more often, especially with Chakra Magic. Illuminate will also heal him for a good amount after hitting many enemy heroes.
  • 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.

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 Play "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 Play "Run! Run, I say!" is a reference to another one of Gandalf's famous quotes: "Fly, you fools!"[2]
    • The respawn lines Play "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 Play "Kundalini!" and Play "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 Play "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 Play "I'll tell thee everything I can, there's little to relate." and Play "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 Play "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.
