Keeper of the Light, also known as Ezalor, is one of the most versatile and impactful support heroes in Dota 2. He offers exceptional lane control, strong crowd control, and the ability to replenish mana for his teammates. While the hero is often picked as a support, his toolkit allows him to impact the game in a variety of roles. This guide will break down his abilities, items, and strategies to help you maximize his potential.

Understanding Keeper of the Light

Keeper of the Light is a ranged intelligence hero with a focus on manipulating the battlefield, providing mana sustain, and creating opportunities for his team. His toolkit includes high-damage abilities that can decimate waves of creeps, as well as defensive spells that disrupt enemies and protect his allies. Ezalor is unique in that he has an ultimate that transforms his playstyle by unlocking new abilities, allowing him to adapt to different stages of the game.

Keeper of the Light’s Abilities

Illuminate

Illuminate is the bread-and-butter ability for Keeper of the Light. It channels a wave of light that damages all enemies in its path. The longer the ability is channeled, the more damage it deals. This makes it a powerful tool for wave clear, harassing enemy heroes, and scouting the fog of war. A fully channeled Illuminate deals massive damage to both heroes and creeps, making it an ideal tool for pushing and defending towers.

The key to mastering Illuminate is positioning. Channel it from behind the treeline or out of the enemy’s line of sight to minimize the risk of being interrupted. Illuminate can also provide vision along its path, making it useful for checking high-ground areas or potential ambushes.

Chakra Magic

Chakra Magic is a utility spell that restores mana to an allied unit while also reducing the cooldown of their next spell. This ability is what makes Keeper of the Light invaluable to mana-hungry heroes. With Chakra Magic, Ezalor can significantly extend the uptime of powerful abilities on his team, making it a great tool for heroes like Medusa, Lina, or Invoker.

You should use Chakra Magic as frequently as possible, especially in the laning phase, to ensure your carry or mid-laner can continually use their abilities. Chakra Magic also allows Keeper of the Light to spam Illuminate more often, keeping the pressure on enemy heroes and securing farm for your team.

Blinding Light

Blinding Light is a situational crowd-control ability that knocks back enemies and reduces their accuracy for a few seconds. This ability is incredibly disruptive in team fights, especially against heroes who rely heavily on right-click attacks. The knockback effect can also be used to push enemies into unfavorable positions, such as off cliffs or away from their targets.

Blinding Light can serve as both an offensive and defensive tool. Offensively, you can disorient the enemy team and force them to regroup, giving your team time to reposition or initiate. Defensively, it can create space for your teammates to retreat or disrupt enemy initiations.

Spirit Form

Spirit Form is Keeper of the Light’s ultimate, transforming him into a powerful caster for a short period. During Spirit Form, Ezalor gains access to two additional abilities: Recall and Will-O-Wisp. Spirit Form also allows Illuminate to be cast by a spirit, freeing Ezalor to move or cast other spells while Illuminate channels.

• Recall: Teleports an allied hero to your location after a short delay. This ability can be a game-changer, allowing you to bring a teammate to a crucial teamfight or save them from danger.
• Will-O-Wisp (Aghanim’s Scepter upgrade): Summons a light wisp that repeatedly stuns all enemies in an area, making it a highly effective crowd control tool for teamfights.

Talent Choices

As Keeper of the Light progresses through the game, his talents provide opportunities to enhance his abilities further:

• Level 10: Choose between a reduced cooldown for Illuminate or an increase in Blinding Light’s miss chance. The choice depends on the game situation, but the Illuminate cooldown reduction is often more useful for keeping up pressure.
• Level 15: Chakra Magic cooldown reduction is an excellent choice as it allows you to spam your spells more frequently.
• Level 20: At this level, the choice between dispelling with Chakra Magic or increasing Spirit Form duration depends on whether you need more utility or extended presence in teamfights.
• Level 25: Both Illuminate damage and Blinding Light stun duration can be game-changing. The extra damage from Illuminate is especially useful for pushing or dealing massive damage in teamfights.

Early Game Strategy

During the early game, Keeper of the Light excels in the laning phase. Use Illuminate to harass the enemy offlaner and clear creep waves from a safe distance. Be mindful of your positioning, as channeling Illuminate leaves you vulnerable to ganks.

Chakra Magic should be used on your lane partner frequently to keep their mana topped up and ensure they can use their abilities as needed. If you’re playing in a dual lane, try to maximize the efficiency of your spells by working with a hero that can benefit from consistent mana regeneration, such as a spell-casting carry.

Additionally, ensure that you’re warding and controlling the lane equilibrium. With Keeper of the Light’s excellent wave-clear potential, it’s easy to push the lane, so be careful not to overextend.

Mid Game Strategy

As you transition into the mid game, Keeper of the Light becomes a powerful asset for map control. Use Illuminate to clear waves and apply pressure on the enemy’s towers. Illuminate can also be used to farm jungle camps and control the creep equilibrium on the map.

Your role during this phase is to rotate between lanes, helping your team secure objectives and providing mana sustain. The combination of Chakra Magic and Blinding Light allows you to disrupt enemy engagements while keeping your team in fighting shape. Use Spirit Form strategically during teamfights, leveraging Recall to bring key teammates into the battle at crucial moments.

The Aghanim’s Scepter upgrade becomes particularly important in the mid game. Will-O-Wisp is a game-changing ability that can single-handedly turn the tide of a fight by controlling large areas of the battlefield and forcing enemies to either fight or flee.

Late Game Strategy

In the late game, Keeper of the Light’s influence on the battlefield becomes even more pronounced. Illuminate’s damage output is significant enough to clear waves and harass enemies from a distance. Combine this with Will-O-Wisp for maximum disruption during teamfights. With the right positioning and timing, you can keep enemies disabled for extended periods, allowing your cores to finish them off.

You should also focus on positioning in the late game. Stay in the backlines to avoid being caught out, and use your high movement speed to stay mobile. Items such as Force Staff, Glimmer Cape, and Scythe of Vyse are essential for survivability and utility. Use Force Staff to escape dangerous situations or to position yourself better for casting Will-O-Wisp and Illuminate.

Item Build

Keeper of the Light benefits from items that enhance his mana regeneration, mobility, and survivability. In the early game, you should focus on Tranquil Boots and a Magic Wand for sustain. Force Staff is a core item that provides mobility and an additional tool for saving teammates or escaping dangerous situations.

Later in the game, Aghanim’s Scepter becomes essential, providing permanent Spirit Form and access to Will-O-Wisp. Guardian Greaves, Glimmer Cape, and Lotus Orb are excellent support items that provide both defensive and offensive utility.

Scythe of Vyse is a powerful item for controlling enemies, and if the game stretches into the late stages, Refresher Orb can be picked up for double Will-O-Wisp or Illuminate.

Mastering Keeper of the Light requires understanding the nuances of positioning, timing, and resource management. By carefully utilizing his abilities and building the right items, you can significantly impact the game, whether by supporting your team, controlling the battlefield, or pushing waves to secure objectives.
