Keeper of the Light/Counters

Bad against...

 * Nyx Assassin is a full-fledge ganker, Keeper's low strength gain and health pool can be suspectible to Nyx's Vendetta.
 * Keeper has balanced mana pool and intelligence, giving Nyx to cast Mana Burn.


 * Attacking Abaddon through out the early game when he's level 6, Abaddon can soak up damage through Aphotic Shield and Borrowed Time.


 * wolf statue can take down the keeper,after Lycan turn in wolf him don't need mp,so mp drain are useless against Lycan.


 * Keeper of the Light lack of fighting ability so LC can get easy victory point from Duel


 * Not only Black King Bar shutdown him. Sven who has crazily damage from God's Strength can kill Kotl after Storm Hammer before he acted.

Good against...
Keeper of the Light can easily soak mana from Timbersaw, meanwhile mana is necessary for Timbersaw
 * Reason

Same as Timbersaw, Earth Spirit needs mana
 * Reason

Both Mana Leak and Blinding Light from Keeper of the Light will be a problem for Bristleback. Mana Leak because Bristle grows stronger if he uses first two abilities, and Blinding Light is because Bristleback, like many other heroes, should chase enemies.
 * Reason


 * Because Wraith King has low mana and his ultimate "Reincarnation" requires high mana, Keeper of the Light's Mana Leak will be a problem for him


 * Keeper of the Light's first skill can easily kill Broodmother's spiderlings and make Broodmother stay with low mana
