* Heroes with spell immunity: Juggernaut, Pangolier, Huskar.

* Wraithfire Blast is quite predictable, and players with good reflexes will disjoint it with Blade Fury.
* Omnislash with Diffusal Blade & Aghanim's Scepter can prevent Wraith King from reincarnating unless he has his Aghanim's Shard that removes the mana cost from Reincarnation.

* Leshrac needs to be close to target in order to do damage, Pugna can outrun Leshrac with ease due to his superior movement speed.
* Split Earth can also be hard to land on Pugna for the same reason.
* Leshrac uses huge amounts of mana to do damage, Nether Ward forces him to either not contribute in a fight or kill himself in the process.
Additional:
* Nether Ward punishes Leshrac's constant mana usage from spamming spells.
* Leshrac needs to be in the thick of the fight to deal damage, and so cannot escape from Nether Blast nor Life Drain easily.

* Heroes who are reliant on physical damage will be nullified by Decrepify: Riki, Wraith King, Juggernaut.

* Mana Break quickly eats away at Wraith King's small mana pool, preventing Reincarnation from triggering before he gets aghanimshard.
* Wraith King has no innate mobility. Even with Blink Dagger, Wraith King is easily kited by Blink.
* Anti-Mage can farm much more quickly than Wraith King, allowing Anti-Mage to overpower Wraith King once a significant farm advantage is established.
Additional:
* Mana Break can prevent Wraith King from reincarnating unless Wraith King has his Aghanim's Shard that removes the mana cost from Reincarnation.
* With Manta Style, his mana burning will triple because illusions can also use Mana Break.

* Anti-Mage can withstand magical burst damage much better than other carries, making him effective against nukers: Lich, Necrophos, Oracle, and Leshrac.

Additional:
* Counterspell severely reduces Leshrac's magical damage.
* Leshrac already burns through his own mana with Pulse Nova, Mana Break will burn through even more.
* Leshrac's high mana pool will increase the amount of damage Mana Void does to him when his mana is low.

* Oracle's Fate's Edict will protect an ally from Leshrac's nuking damage.
* Oracle's False Promise can dispel Leshrac's stun and slow from his abilities, allowing an ally to escape.
* Fortune's End can stop Leshrac from chasing opponents or running away.

* Heroes with area dispel can kill multiple skeletons at once: Brewmaster, Oracle.

* Sanity's Eclipse does massive damage to Wraith King who naturally has a low mana pool and typically doesn't build items to increase it.
* Wraithfire Blast's slow projectile speed makes it easy to avoid using Astral Imprisonment.

* Leshrac's high magic damage is ignored by Rage.
* Lifestealer can get in Leshrac's face with Rage and mitigate any other damage taken by Leshrac with Open Wounds.

* Weaver can run away after killing Wraith King once thanks to Shukuchi.
* Wraithfire Blast is quite predictable. If Weaver is quick, he will disjoint it with Shukuchi and proceed to chase Wraith King down.
* Shukuchi does have a fade time. They cannot disjoint it if you use it right next to them. They will be stunned and take damage; however they will still become invisible if they used Shukuchi before the stun hits.
* Weaver can easily harass Wraith King out of his lane thanks to his high base damage and Geminate Attack.
* Weaver can burn Wraith King's mana quickly with his Mana Break or Diffusal Blade, until Wraith King purchases Aghanim's Shard to remove Reincarnation's manacost.
Additional:
* Wraithfire Blast is easy to disjoint with Shukuchi or Time Lapse, and it's the only way to break Weaver's Linken Sphere.
* Wraith King has no other disables and no mobility, allowing Weaver to chase or escape Wraith King as he wishes.
* With the Mana Break talent and Diffusal Blade, Weaver can prevent Reincarnation from triggering until Wraith King gets his shard.

* Nyx Assassin's Spiked Carapace will stun Leshrac when hit by any of his AOE abilities.
* Mana Burn deals high damage due to Leshrac's high intelligence gain and burns a large amount of Leshrac's essential mana pool.

* Riki is a natural Diffusal Blade carrier, and it doesn't help that he's easily capable of sneaking up on you due to Cloak and Dagger.
* Riki can use Smoke Screen on top of you as you're reincarnating, making you a sitting duck for your second life. In addition, the blind prevents Wraith King from landing critical hits from Mortal Strike.
* Wraithfire Blast is quite predictable, and players with good reflexes will disjoint it with Tricks of the Trade.
* There is also a chance he will become invisible again as the projectile travels, disjointing it.

* Wraith King has no form of AoE to clear Chaos Knight's illusions from Phantasm.
* Wraith King is very vulnerable if he reincarnates in the middle of his illusions.

* Invoker can drain Wraith King's mana with EMP, preventing him from reincarnating unless Wraith King has his Aghanim's Shard.
* Even if Wraith King survives and reincarnates, Invoker still has an arsenal of spells to lockdown Wraith King, including an easily setup Ice Wall.
* Tornado applies an area dispel to clear skeletons.
Additional:
* EMP allows Invoker to burn Wraith King's mana to prevent Reincarnation from triggering (only until Wraith King gets his Aghanim's Shard).
* Ice Wall and Cold Snap are particularly crippling for Wraith King as they allow to kite him very effectively, preventing him from dealing melee attack damage.

* Wraith King's poor mobility makes him vulnerable to Illuminate.
* Blinding Light can reduce his damage output as well as his already abysmal mobility.
* Chakra Magic drains Wraith King's much-needed mana resulting in him not being able to reincarnate

* Wraith King has no form of AoE to clear Terrorblade's illusions.
* Terrorblade is a common Manta Style and Diffusal Blade carrier.
* Terrorblade has very high armor, which helps against Wraith King's physical-only damage.
* A reincarnated Wraith King is an ideal target for Sunder if Terrorblade's health is low.
Additional:
* Terrorblade has very high armor gain, which helps him against Wraith King's physical damage.
* Wraith King is not good against illusion-based heroes as he has no AoE form abilities to deal with Terrorblade's Illusions.
* Terrorblade is a common Manta Style and Diffusal Blade carrier to deal with Reincarnation until Wraith King has Aghanim's Shard.
* A Reincarnated Wraith King is a good setup for Sunder if Terrorblade's health is low enough.

* Heroes who rely on basic attacks will suffer from Laser: Phantom Assassin, Wraith King, Huskar.

* Clinkz, Sniper, Lone Druid, Troll Warlord, Legion Commander and Wraith King are some of the Heroes that base themselves on attacks with little or no spell power, so they suffer in the grassy hands of Overgrowth.

* Heroes with spell immunity: Juggernaut, Pangolier, Huskar.

* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use Dark Rift to get to a designated point of the map: Phantom Assassin, Terrorblade, Troll Warlord, Drow Ranger, Phantom Lancer, Chaos Knight, Sven, Wraith King, Bounty Hunter, Alchemist, Templar Assassin, Nyx Assassin, Bane.

* Heroes with area dispel can kill multiple skeletons at once: Brewmaster, Oracle.

* Wraith King, Medusa, Storm Spirit and other mana dependent heroes will have diminished impact on a fight if they survive Fiend's Grip due to its mana steal.

* Many physical-only single-target heroes like Lifestealer, Sven, Wraith King, Phantom Assassin, Templar Assassin etc.

* Heroes who Sniper can kite: Sven, Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.

* Heroes with long cast animations can be continuously interrupted by Battery Assault: Centaur Warrunner, Jakiro, Leshrac, Naga Siren, Underlord.

Additional:
* Clockwerk naturally builds Blade Mail, reflecting Leshrac's high magic damage output back at him.
* Power Cogs will prevent Leshrac from reaching Clockwerk's team and dealing large AOE damage to them.
* Power Cogs will also keep Leshrac close, wasting his Diabolic Edict on just Clockwerk.
* Battery Assault interrupts Leshrac's long cast times of Split Earth and Lightning Storm.

* Heroes with spell immunity: Juggernaut, Pangolier, Huskar.

* Wraith King's lack of area of effect spells makes him easily overwhelmed by Beastmaster's summons.

* Dark Pact, if timed correctly, can dispel Wraithfire Blast's stun and slow.
* Since Wraith King has a lot of health and multiple lives, Slark can keep gaining Essence Shift stacks, increasing armor, damage, and attack speed and can beat down Wraith King twice.
* Slark sometimes carries Diffusal Blade to burn mana as an attempt to shut down Reincarnation.
* Because Wraith King has no AoE abilities, Shadow Dance is particularly useful against Wraith King.

* Wraith King has no ability to destroy trees from Tree Dance.
* Monkey King tends to get Diffusal Blade, leaving Wraith King no mana to reincarnate unless Wraith King has his Aghanim's Shard.
* A reincarnated Wraith King is an ideal target for Wukong's Command.

* Wraith King has a very low mana pool and depends on it to cast Reincarnation. Mana Drain will render him useless.
* Wraith King has very low mobility, making it easy for Lion to disable and harass him.
Additional:
* While not being able to confront Wraith King by himself, Lion's Mana Drain helps in draining Wraith King's mana, preventing him from reincarnating unless he has his Aghanim's Shard.
* Lion's Earth Spike and Hex provide decent lockdown against Wraith King as well, preventing the latter from benefiting from Vampiric Spirit bonuses.
