* Riki is known for being a successful support killer, and not just for show. He can give you one hell of a time by constantly picking you off and/or forcing you to stick close to the rest of the team.
* Smoke Screen is particularly devastating to Shadow Shaman. With neither his various disables nor a solid health pool Shadow Shaman is usually dead. Consider a force staff if you find yourself in this scenario (to force yourself out of the cloud before shackling Riki) and buy sentry wards if you have the money.

* 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.

* Support heroes with low mobility can be slowed further by Incapacitating Bite, and swarmed by Spiderlings for an easy kill: Shadow Shaman, Visage, Dazzle, Rubick, Lich.

* Broodmother can easily clear Wraith King's skeletons with Spawn Spiderlings and summon spiderlings in their place.
* With Diffusal Blade, Broodmother can prevent Wraith King from reincarnating unless the level 20 talent is chosen.

* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane, Beastmaster, Bloodseeker, Clockwerk, Doom, Shadow Shaman.

* 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.

* 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.

* Nyx Assassin, Bounty Hunter and Slark can all sneak up and kill you, Nyx being particularly deadly. Watch Slark carefully, as he can break either (but not both unless you are making a mistake) of your disables, with Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn you from prey to predator.

* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna

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

* Mirana can disturb your channeling even if you are under the effect of invisibility thanks to Sacred Arrow.
* Mirana armed with an Aghanim's Scepter is known to be able to quickly burst down heroes - especially supports. Together with Ethereal Blade the bullying can continue for the whole match.

* Necronomicon Warrior's Mana Break can deplete Wraith King's mana and prevent him from using Reincarnation.
* Wraith King's lack of area of effect spells makes him easily overwhelmed by Beastmaster's summons.

* Due to their high attack speed, Summon Familiars will destroy Mass Serpent Ward quickly, granting Visage a massive amount of gold.
Additional:
* Due to their high attack speed, Visage's Summon Familiars will destroy Mass Serpent Ward quickly, granting Visage massive amount of gold.

* Shadow Shaman has no effective burst damage, thus Chen has a lot of time to save an ally with his creeps or Hand of God from a gank.
* Chen can use {U:Centaur Conqueror} or {U:Mud Golem} to interrupt Shadow shaman's Shackles channeling
* Mass Serpent Ward can be easily teared down by Chen's creep army

* 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 picks the level 20 talent that removes the mana cost from Reincarnation.

* As a caster, Anti-Mage's Mana Break and Mana Void are highly effective against him.

* Mana Break quickly eats away at Wraith King's small mana pool, preventing Reincarnation from triggering.
* 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 picks the level 20 talent that removes the mana cost from Reincarnation.
* With Manta Style, his mana burning will triple because illusions can also use Mana Break.

* Dragon Knight can simply tank and destroy all Shadow Shaman's Serpent Wards.

* Waveform allows Morphling to escape from Mass Serpent Ward
* Morphling can interrupt Shadow Shaman while he is shackling an ally with Adaptive Strike (Strength).
* With Ethereal Blade Morphling can quickly burst him down before he even has a chance to react.

* 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.
* Lion's Earth Spike and Hex provide decent lockdown against Wraith King as well, preventing the latter from benefiting from Vampiric Aura bonuses.

* 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.

* Diffusal Blade lets Phantom Lancer drain Wraith King's mana, preventing Reincarnation from triggering until he upgrades his talent point at level 20.
Additional:
* Doppelganger disjoints Wraithfire Blast.
* Wraith King is not good at handling illusion-based heroes, as his only disable is single-target.
* Phantom Lancer tends to get Diffusal Blade, leaving Wraith King no mana to reincarnate.

* 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

* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven, Tiny, Wraith King, Dragon Knight, Meepo, Doom, Bounty Hunter, Dark Seer, Undying, Alchemist, Legion Commander.

* Omniknight can dispel Hex or Shackles with Heavenly Grace. He can also heal teammates which you disabled. The same goes to Abaddon's Aphotic Shield .

* With 4 active abilities, Shadow Shaman is weak against silencing foes such as silencer, Drow Ranger and Death Prophet.

* Arc Warden with his Magnetic Field will protect allies from Mass Serpent Ward.

* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: Ancient Apparition, Crystal Maiden, Shadow Shaman, Skywrath Mage etc.

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

* 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.

* Omniknight can dispel Hex or Shackles with Heavenly Grace. He can also heal teammates which you disabled. The same goes to Abaddon's Aphotic Shield .

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

* Nyx Assassin, Bounty Hunter and Slark can all sneak up and kill you, Nyx being particularly deadly. Watch Slark carefully, as he can break either (but not both unless you are making a mistake) of your disables, with Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn you from prey to predator.

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

* Meepo has a better advantage in farm with Divided We Stand, as well as having a higher attack speed due to his tendency to build items that give attributes. In addition, Wraithfire Blast stuns only one target, and choosing to engage one Meepo will most certainly mean engaging them all.

* Pudge, Legion Commander and Axe will make the match a living hell for you, since they are known for surprise attacks from the fog and quickly killing low HP heroes. They can also interrupt your channeling, Legion being especially problematic, as she can use Press the Attack on an ally who is hexed as well.

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

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

* With 4 active abilities, Shadow Shaman is weak against silencing foes such as silencer, Drow Ranger and Death Prophet.

* Heroes with summons and illusions such as Broodmother and Naga Siren, are ill-suited for Wraith King to fight, as he has no source of waveclear.

* Heroes that lack burst damage will have a difficult time taking down Monkey King, and fare badly against Jingu Mastery: Legion Commander, Lifestealer, Weaver, Wraith King

Additional:
* 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.
* A reincarnated Wraith King is an ideal target for Wukong's Command.

* Pudge, Legion Commander and Axe will make the match a living hell for you, since they are known for surprise attacks from the fog and quickly killing low HP heroes. They can also interrupt your channeling, Legion being especially problematic, as she can use Press the Attack on an ally who is hexed as well.

* Heroes with single-target abilities will be overwhelmed by Lycan and his summons: Wraith King, Bane, Phantom Assassin.

* Invoker can drain Wraith King's mana with EMP, preventing him from reincarnating.
* 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 level 20 talent).
* 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.
