* {U:Familiar}s have flying vision. They can be used to scout Monkey King when he is in the tree.
* Stone Form can destroy the tree Monkey King is standing on.

* Chaotic Offering can destroy the tree Monkey King is standing on.
* Shadow Word and Fatal Bonds constantly puts Tree Dance on cooldown.

* Channeling heroes will not go well against Warlock, especially those who build Black King Bar as Warlock's ultimate ability stun goes through spell immunity. E.g.: Crystal Maiden, Shadow Fiend, Enigma, etc.

* Grave Chill will make Crystal Maiden's bad movement speed even worse.
* Soul Assumption charges can easily be stacked up from Freezing Field, allowing Visage to nuke enemies multiple times throughout the fight.
* {U:Familiar}'s Stone Form can also be used to interrupt Freezing Field, even while Crystal Maiden is under the effects of Glimmer Cape. Crystal Maiden must purchase a Black King Bar, which is far more costly.

* Chaotic Offering's spell immunity piercing stun can stop Black Hole's channeling. Due to this ability's large area of effect, it can be cast at a safe distance from the Black Hole.
* Fatal Bonds can be used to make Enigma's Eidolons easier to kill, potentially feeding the enemy team.
* Warlock's Upheaval can interfere with Enigma's initiation and potential follow-ups thanks to its large AoE.
Additional:
* Chaotic Offering pierces spell immunity and is an area of effect ability, therefore it doesn't matter if Enigma buys Black King Bar or Linken's Sphere Warlock will always be able to cancel channeling of Black Hole.
* Enemies often get clumped up around Black Hole giving Warlock a perfect opportunity to cast Fatal Bonds and Upheaval on multiple enemies.

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

* Heroes that deal few, powerful instances of damage, like Oracle, Lion, or Sven, have a hard time breaking through Gravekeeper's Cloak.

* While heroes with strong mobility able to get close/flee or long range disables do well against him, heroes with no escaping abilities/lacking long disables will perish against Warlock. Once the {U:Warlock Golem} lands with its stun, its hardly possible to escape when he casts Upheaval. Just watch your pet burn the enemies as they try running away or blow their strongest abilities to stop your {U:Warlock Golem}. Notable examples: Huskar, Drow Ranger, Lion, Elder Titan, etc.

* Familiars will be able to chase Spectre through the trees when she uses Spectral Dagger, while Visage can keep blasting her with Soul Assumption.
* Desolate will almost never proc because Visage will always have nearby Familiars.

* Nature's Prophet has no innate way to deal with Gravekeeper's Cloak or kill {U:Familiar}s effectively.
* Familiars can fly over the trees created by Sprout. They can also use Stone Form when the Prophet is trying to use Teleportation.
Additional:
* Nature's Prophet has no natural method of dealing with Gravekeeper's Cloak and Familiars.
* Familiar's low base attack time can chip away Nature Prophet's health.
* Familiar's Stone Form destroys trees created by Sprout.
* Familiars can scout woods and foggy areas where Nature's Prophet is trying to use Teleportation.

* Lacking escaping mechanisms, being dependent on fair positioning and channeling for his ultimate, its easier to Warlock with your long range crowd control abilities to lock the Shadow Fiend down to your team.

* Pudge has a very hard time killing Familiars due to his melee range and low attack speed.
* Stone Form can quickly interrupt Dismember.

* Chaotic Offering's vast area-effect can destroy trees and stun Hoodwink.
* Upheaval makes retreating with Scurry difficult.

* Summon Familiars can scout Techies as they are placing mines. They even trigger Stasis Trap.

* {U:Familiar} can spot Clockwerk, allowing Visage's allies to dodge or block Hookshot attempts.
* Familiars will not be damaged by Blade Mail or Clockwerk's abilities, dealing dangerous amounts of damage to him.
Additional:
* Familiars can scout for Clockwerk's location allowing Visage to dodge or block Hookshot attempts.
* Gravekeeper's Cloak greatly absorbs damage from Hookshot.

* 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.

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

* Warlock often stays back and counter-initiates by dropping his Chaotic Offering on Earthshaker and his allies.

* Visage can quickly kill heroes with low to medium base armor and no innate escape mechanism. Examples include Alchemist, Crystal Maiden and Zeus.

* While heroes with strong mobility able to get close/flee or long range disables do well against him, heroes with no escaping abilities/lacking long disables will perish against Warlock. Once the {U:Warlock Golem} lands with its stun, its hardly possible to escape when he casts Upheaval. Just watch your pet burn the enemies as they try running away or blow their strongest abilities to stop your {U:Warlock Golem}. Notable examples: Huskar, Drow Ranger, Lion, Elder Titan, etc.

* Illusion and heroes with summons are difficult to kill with Chen's single-target offensive spells: Terrorblade, Phantom Lancer, Chaos Knight, Broodmother, Naga Siren, Lycan, Visage. However, Chen can convert enemy summons with Holy Persuasion, as long as they don't bunch up.

* Familiars will easily be able to kite heroes with a short range or with low attack speed. For example, Tiny and Undying have a very hard time killing Familiars.

* Because Oracle uses few, powerful instances of damage to kill enemies, Templar Assassin's Refraction and Visage's Gravekeeper's Cloak can absorb his burst damage.

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

* Visage can quickly kill heroes with low to medium base armor and no innate escape mechanism. Examples include Alchemist, Crystal Maiden and Zeus.

* Fatal Bonds links the Meepos together.

* Gravekeeper's Cloak protects Visage from Legion Commander's attacks for most of Duel's duration.
* Chain stuns from Visage's familiars prevents Legion Commander from winning Duels.

* {U:Warlock Golem}s do plenty of physical and pure damage to bring down Huskar when he is at low health. Warlock is always a hazard for Huskar to initiate by using Life Break because Chaotic Offering can stun him instantly, even when Black King Bar is activated, and allow Warlock's team to gather their wit and retaliate.
* After jumping in, Huskar will not have any means to escape Upheaval. Being an attack-dependent hero, this is bad for him.

* Stone Form's long stun duration may prevent Puck from using escape abilities.
* Visage frequently builds Rod of Atos for the root that will make Puck unable to move and use his escape abilities.

* Heroes with summons: Lycan, Broodmother, Visage.

* Familiars will easily be able to kite heroes with a short range or with low attack speed. For example, Tiny and Undying have a very hard time killing Familiars.

* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a Dust of Appearance can be great at shutting her down early game: Earth Spirit, Spirit Breaker, Tusk, Bounty Hunter, Riki, Warlock.

Additional:
* Warlock can cast Upheaval when Templar Assassin uses Meld, preventing escape.
* Warlock can also send his {U:Warlock Golem} near where she used Meld, preventing escape by Blink Dagger due to the {U:Warlock Golem} Permanent Immolation.

* While heroes with strong mobility able to get close/flee or long range disables do well against him, heroes with no escaping abilities/lacking long disables will perish against Warlock. Once the {U:Warlock Golem} lands with its stun, its hardly possible to escape when he casts Upheaval. Just watch your pet burn the enemies as they try running away or blow their strongest abilities to stop your {U:Warlock Golem}. Notable examples: Huskar, Drow Ranger, Lion, Elder Titan, etc.

* Familiars deal many instances of damage quickly, minimizing the effectiveness of Spiked Carapace. They are, however, relatively fragile and can be killed quickly with Nyx Assassin's high burst damage, especially from Vendetta.
* Gravekeeper's Cloak and tanky item builds make him hard to kill with burst damage.
* Visage's long range on Soul Assumption and Grave Chill make him hard to escape from, and Soul Assumption's low cooldown outmatches Spiked Carapace.
