* Because Warlock's abilities are all active abilities, Silencer can make his impact minimal.
* Arcane Curse prevents Warlock from using his abilities without taking 56/84/112/140 damage, and slowed by 9%/12%/15%/18%.
* Last Word can prevent Warlock from casting his combo.
* Global Silence can nullify Warlock's impact in fights and prevent him from getting any spells off.

* Like any hero with a channeled spell, Last Word is a counter to it.
* Global Silence goes through spell immunity and prevents Witch Doctor from casting his spells.

* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some Heroes might disrupt or sneakily pass through your allies and deal with you, preventing you from doing your job. Such heroes include Chaos Knight, Spirit Breaker, Riki, and some others.

* Without Dust of Appearance or Sentry Wards, Riki is able to silence Witch Doctor with Smoke Screen, and is likely to build a Diffusal Blade, leaving Witch Doctor without mana to cast Voodoo Restoration, as well as Skull Basher to interrupt Death Ward.

* Heroes like Slark, Witch Doctor and others also tend to suffer in Ice Blast's heal denial.

* Ice Blast nullifies the healing from {U:Warlock Golem} and Shadow Word.
* Cold Feet stuns Warlock if he chooses to continue channeling Upheaval.

* Heroes with long channeling abilities like Witch Doctor are easy targets for Kunkka to interrupt in team fights.

* Ghostship helps your team soak up damage from Chaotic Offering and hit summons hard.
* Tidebringer clears summons later in the game.
* Most of your spells can interrupt Upheaval.

* Heroes that have small health pools and little to no escape mechanisms are even easier prey for Necrophos. Ghost Shroud's slow will allow him to catch him with them, and get nuked down with his abilities, even preventing retaliation due to Reaper's Scythe's stun. Such heroes include Crystal Maiden, Witch Doctor, Warlock or Shadow Fiend.

* Heroes that have small health pools and little to no escape mechanisms are even easier prey for Necrophos. Ghost Shroud's slow will allow him to catch him with them, and get nuked down with his abilities, even preventing retaliation due to Reaper's Scythe's stun. Such heroes include Crystal Maiden, Witch Doctor, Warlock or Shadow Fiend.

* Low health spellcasters: Lina, Witch Doctor, Tinker, Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.

* Because all of Warlock's abilities are active abilities, silences can make his impact in fights minimal. Be cautious of heroes that carry silences like Death Prophet, Puck, and the aforementioned Silencer.

* Surge allows for Dark Seer and his allies to escape from Upheaval due to it ignoring any slow.

* Vengeful Spirit has two abilities to interrupt Death Ward, even through Black King Bar.

* Sacred Arrow can be used to interrupt Death Ward from a safe distance, forcing him to cancel it to dodge or get hit.
* Paralyzing Cask is a slow-moving stun, and Mirana can Leap away from her allies to keep it from bouncing.
* Witch Doctor has low health and can easily be killed with an Aghanim's Scepter combo or just when hit with an arrow.

* Wraithfire Blast cancels Death Ward in decent range.
* Death Ward is meaningless while Reincarnation is off cooldown.
* Vampiric Aura can out-heal the {tooltip:DoT|Damage over Time} from Maledict.

* Mana Break prevents Warlock from casting his spells.
* Blink allows Anti-Mage to escape from Upheaval.
* Counterspell reduces damage from Shadow Word and the {U:Warlock Golem}'s Permanent Immolation.
* Mana Void deals heavy damage after Chaotic Offering and interrupts Upheaval.

* It is especially easy for Oracle to negate the damage from Maledict, and even heal through it with Fate's Edict and Purifying Flames.
* If by some miracle an enemy is still about to die because of Maledict, he can still save him with False Promise.

* With God's Strength, Warlock Golem goes down in a matter of seconds. The two weaker golems granted by Aghanim's Scepter will fare worse due to Great Cleave hitting both.
* Storm Hammer upgraded with level 15 talent dispels Shadow Word.
Additional:
* God's Strength combined with Great Cleave destroys Chaotic Offering golems within seconds.

* Beware of placing the Death Ward if Chronosphere is off cooldown, as it will cancel the effect and leave Witch Doctor vulnerable if he does not react in time.

* Kraken Shell dispels the stun from Paralyzing Cask. However, it does not dispel the damage from Maledict.
* Once Witch Doctor first uses his Death Ward in team fights, Tidehunter can simply cancel it with Ravage, turning the tables against him, especially if Witch Doctor does not have a Black King Bar.
* As a precaution, let Tidehunter use Ravage first before channeling Death Ward to turn a team fight in your favor.

* Lucent Beam interrupts Death Ward from a decent range.
* Eclipse kills Witch Doctor during Death Ward, even through Glimmer Cape.

* Weaver's Shukuchi allows him to escape from Warlock's Upheaval with maximum move speed.
* His ultimate Time Lapse allows him to ignore damage from {U:Warlock Golem} and escape.

* Guardian Angel protects allies from Death Ward's physical damage.
* Purification and Heavenly Grace will most likely save teammates from dying to Maledict.

* Impale interrupts Upheaval.
* Nyx Assassin Vendetta allows him to escape from Warlock's Upheaval with maximum move speed.
* Warlock's low health pool and mobility can easily take down by Nyx Assassin's burst damage.

* Every ability Witch Doctor has is useful when Rubick manages to steal any of them:
* Paralyzing Cask provides an additional disable apart from Telekinesis and also helps Rubick to farm.
* Voodoo Restoration provides utility by healing Rubick and his team, since he has no heal of his own.
* Maledict is a solid damage-over-time nuke, which can be devastating to the enemy team.
* And most importantly, Death Ward is one of the best teamfight spells in the game. It also requires channeling, which makes it easy for Rubick to steal. And when combined with Aghanim's Scepter, this can prove deadly to the enemy team.
* However, a skilled Witch Doctor will always toggle Voodoo Restoration while channeling Death Ward to prevent that.
Additional:
* Rubick can steal Death Ward easily as it is a channeled ability and then use it to turn teamfight to his advantage.
* However, a skilled Witch Doctor will toggle Voodoo Restoration immediately after placing his Death Ward to prevent that.

* Death Ward does little damage against Dragon Knight's armor, and Dragon Knight's high health regeneration minimizes damage from Maledict.

* Upheaval does not interrupt Slark too much, as he can just Pounce out of the area.
* Fatal Bonds and Shadow Word can be dispelled by Dark Pact.

* Morphling can Attribute Shift to strength after being hit by Maledict. Since Maledict deals its damage based on the difference between HP on cast and HP after two seconds, odds are Morphling will have more HP than when Maledict was cast, thus resulting in no damage.
* On the upside, players prone to panicked reactions may Morph to agility, making Maledict even more efficient than intended.
* Adaptive Strike (Strength) can interrupt Death Ward at a decent range.

* A pre-placed Fire Remnant allows Ember Spirit to escape Upheaval.
* Flame Guard blocks Shadow Word's damage.
* Sleight of Fist allows Ember Spirit to attack from range, ignoring Upheaval, and Searing Chains lets him interrupt it.

* Heroes with plenty of summons, such as Broodmother or Nature's Prophet can have their minions soak up most of your Paralyzing Cask.

* Arc Warden's Magnetic Field dodges all damage from Death Ward. Should he choose to buy a Necronomicon, they are quite effective to absorb some shots from your cask, and attack you during Death Ward.

* Heroes that wish to disrupt fights with spell combos or big ultimates are vulnerable to the long stun of Fiend's Grip: Disruptor, Death Prophet, Enigma, Faceless Void, Invoker, Lich, Magnus, Mars, Medusa, Outworld Devourer, Phoenix, Puck, Queen of Pain, Shadow Fiend, Treant Protector, Underlord, Winter Wyvern, Witch Doctor, Zeus.

* Generally, any fragile heroes will have a hard time dealing with Undying's tankiness, and even more so if Decay is used on them. Some examples are Crystal Maiden and Witch Doctor.

* Stone Form can easily interrupt heroes with long channeling spells, like Crystal Maiden, Bane, Witch Doctor, or Enigma.

* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some Heroes might disrupt or sneakily pass through your allies and deal with you, preventing you from doing your job. Such heroes include Chaos Knight, Spirit Breaker, Riki, and some others.

* Low mobility heroes: Heroes with no/little means of traveling fast have difficulty getting to/away from Bounty Hunter due to his slowing Jinada and hastening Track. Few examples of such heroes are: Crystal Maiden, Sniper, Ursa, Witch Doctor, etc.

* Death Ward's first target (before it bounces) can evade it, therefore Windranger and Phantom Assassin are poor choices to use it on.
* However, once the first hit landed, the bounces can no longer miss. Don't forget to manually aim for a target with no evasion !

* Heroes who rely on summons will see them destroyed easily by Overwhelming Odds: Lycan, Arc Warden, Warlock, Chen

* Heroes with slow movement speeds and small health pools (supports like Crystal Maiden or Witch Doctor) are easy targets for Phoenix. Should they be inflicted by its DOT debuffs, they will be very quickly killed without even getting a chance to fight back.

* Because all of Warlock's abilities are active abilities, silences can make his impact in fights minimal. Be cautious of heroes that carry silences like Death Prophet, Puck, and the aforementioned Silencer.

* Heroes who rely on channeling abilities can be interrupted in teamfights by Rolling Thunder: Crystal Maiden, Pugna, Witch Doctor

* Death Ward's first target (before it bounces) can evade it, therefore Windranger and Phantom Assassin are poor choices to use it on.
* However, once the first hit landed, the bounces can no longer miss. Don't forget to manually aim for a target with no evasion !

* Heroes who have channeled abilities can be stunned by Light Strike Array, like Witch Doctor with Death Ward and Bane's Fiend's Grip.

Additional:
* Light Strike Array cancels out Death Ward from a long distance.

* Heroes that have a channeled ability can be interrupted by Meat Hook: Pugna, Witch Doctor, Enigma, Bane.

Additional:
* Meat Hook interrupts Death Ward from a decent range, even through Black King Bar & Glimmer Cape.
* Pudge can survive the damage from Maledict because of his Flesh Heap stacks.
* However the damage-over-time from Rot is counteracted by Voodoo Restoration.

* Ursa can shred {U:Warlock Golem}s in a few seconds with Fury Swipes and Overpower.

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

* Heroes with powerful channeling abilities are easily interrupted by Phantom's Embrace: Bane, Pudge, Witch Doctor, Crystal Maiden, Enigma.

* Heroes with plenty of summons, such as Broodmother or Nature's Prophet can have their minions soak up most of your Paralyzing Cask.
