Keeper of the Light/Guide

Lane Support
To play a straightforward Keeper of the Light, max out Chakra Magic as soon as possible and focus on keeping your teammates' mana supply up. A value point in Illuminate offers some damage, especially if teammates have lockdowns to help you land it. You can still land Illuminate by yourself if you channel out of vision, like among trees, and toward lane creeps where enemies will most likely go to get farm. However, it does not always work against opponents who can stand their ground like, trade hits with you like with , can stay without mana like , or have dispels like.

Maxing out Chakra Magic works best if you have a lane partner who can make good use of the mana to launch spells at the enemy. A steady barrage of s, s, or s can go a long way to secure your lane and possibly net a kill.

Keeper of the Light usually wears, as he does not really need the mana provided by Arcane Boots, so you can start the game with for a minor movement speed boost. If you are planning on building, then you can keep until you already finished the Mekansm. You can play Keeper of the Light as a selfless position 6, buying every support items for team.

General

 * Keeper of the Light has low strength and armor, thus he relies on positioning and powerful abilities to stay alive.
 * Keeper of the Light pushes and defends the base well, as he can replenish teammates' and his own mana with Chakra Magic, allowing profligate use of pushing abilities, and Illuminate can nuke entire creep waves.
 * Play Keeper of the Light in the safelane to harass enemy with his formidable abilities. He can also play in the offlane to disrupt the enemy carry from getting farm.


 * Illuminate allows Keeper of the Light to output a large amount of damage on a low cooldown.
 * Illuminate's strong creep-killing power makes Keeper of the Light a remarkably good farmer and counter-pusher considering his support role, as he can use it to either knock down large creep waves approaching a friendly tower or blast multiple neutral camps at once. Therefore, he should max Illuminate first to farm up items.
 * However, Illuminate will only deal more damage the longer you channel, which makes it tricky to land on slippery enemies.
 * You can keep Illuminate at lower level for lower mana cost, saving skill points for other abilities if you do not plan to farm creeps.
 * When using Illuminate to harass or nuke an enemy player, try to channel in the fog of war, such as behind the treeline, to give away as little warning as possible.
 * Rely on teammates or Will-O-Wisp to immobilize the enemy long enough to channel the full duration of Illuminate during a gank.
 * Using Illuminate on creep waves early on may disrupt the farm of your lane partner by killing the creeps which will push the wave closer to the enemy's tower. So, you should aim Illuminate only to damage enemy heroes by targeting the wave either at an oblique angle or behind the creep wave.
 * Illuminate reveals fog of war in front of Keeper of the Light while channeling, allowing him to gain flying vision. Remember that charging it to fulmination increases its sight range while releasing it immediately will not gain you much vision.


 * Blinding Light displaces enemies and applies a miss chance on their regular attacks, making it a great teamfighting ability, and especially against attacking carries.
 * The miss chance may reduce the effectiveness of the enemy's physical attacks, giving your team an advantage.
 * However, enemies with True Strike, spell immunity, or dispels can counter Blinding Light's debuff.
 * In the laning stage, apply miss chance on the enemies so they cannot trade hits with Keeper of the Light.
 * Use Blinding Light to clear leftover creeps after Illuminate.
 * Blinding Light will not interrupt enemy channeling.
 * In some cases, the displacement forces the enemies to traverse more ground to reach their destination.
 * Blinding Light's displacement can move enemies over terrain, up or down a cliff wall, which may shut down an enemy melee carry if they do not have any re-positioning abilities or items to reverse the terrain displacement.
 * Use Blinding Light's forced movement when escaping to push enemies away from Keeper of the Light.


 * Chakra Magic allows Keeper of the Light to replenish a significant amount of mana for himself and his allies, allowing to use abilities more often.

Heroes with strong disables but small mana pools like, , , , and can use their stuns liberally to set up kills, while those with powerful harass abilities like , , and  can put continuous pressure on the lane opponents.
 * Put at least two points into Chakra Magic in the laning stage, as its efficiency increases more than twofold.
 * Chakra Magic reduces the cooldowns of basic abilities. So, use Chakra Magic on teammates with low-cooldown disables and initiation spells, since it allows them to use two stuns or nukes in quick succession, increasing the amount of crowd control and damage. Also, it affects passive abilities with cooldowns, benefiting abilities such as, , and.
