* Wall of Replica can create stronger illusions of Terrorblade.

Additional:
* Dark Seer's Vacuum and Ion Shell allows him to clear the wave of Terrorblade's illusions.
* Wall of Replica can create stronger illusions of Terrorblade.
* If Dark Seer can use Vacuum to help teammates land their AoE skills, Terrorblade will be quickly killed before he even gets a chance to use Sunder.

* 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.

* Ember Spirit can deal devastating damage to illusion heroes like Terrorblade with Sleight of Fist. Terrorblade also has no way of preventing Ember Spirit from getting Activate Fire Remnant off. Additionally, Ember Spirit's ability to fight from long range as well as his wide skill set won't give many opportunities for Terrorblade to get Sunder off.
Additional:
* Ember Spirit can deal devastating damage to Terrorblade and his illusions with Sleight of Fist.
* Terrorblade has no disable to lock down Ember Spirit and prevent him from escaping with Fire Remnant. In addition, he doesn't like purchasing disabling items, which are the only solutions to deal with Ember Spirit.

* Reaper's Scythe can kill Terrorblade quickly before he has chance to use Sunder.
* Ghost Shroud protects Necrophos against Terrorblade's high attack damage.

* 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.

* Enrage's damage reduction helps Ursa survive after Terrorblade has used Sunder.

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

* 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.

* All of Puck's damaging spells deal AoE magic damage, which focuses on Terrorblade's low health pool and ignores his armor.
* Puck's spells are also great at quickly clearing all of Terrorblade's illusions. Even a single Illusory Orb is enough to drop their health very low, allowing creeps, towers or allies to finish them off very quickly. Waning Rift and Illusory Orb together are usually enough to clear his illusions.
* Waning Rift prevents Terrorblade from casting Sunder at low health.
* Puck is a common Dagon carrier, so he is able to finish of Terrorblade before he has a chance to Sunder.

* Blood Rite can silence Warlock, which as a spellcaster is bad for him.

Additional:
* Storm Spirit heavy magic damage bypass Terroblade high armor.
* Ball Lightning can either use to initiates Terroblade from distance or kite Terroblade from using Sunder as he has no source of disable to deal with Storm Spirit.

* Void Spirit's arsenal of magic damage is effective against Terrorblade's low strength.
* Terrorblade has no disables to prevent Void Spirit from escaping.

* All of Shadow Shaman's abilities totally ruin Terrorblade: Ether Shock destroys his illusions, Hex prevents him from using Sunder or Manta Style in bad situations, Shackles not only that prevent him from using Sunder, but he has no way to cancel it and Mass Serpent Ward can help Shadow Shaman push faster than Terrorblade even in Metamorphosis.
Additional:
* Ether Shock can destroy Terrorblade's illusions.
* Hex prevents Terrorblade from using Sunder or Manta Style in bad situations. Hex can also destroy one of his illusions.

* Reactive Armor negates most of Terrorblade's damage against Timbersaw, and its high health regeneration and armor bonuses can help Timbersaw survive after being Sundered.

* 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.

* Terrorblade's low base health and lack of mobility make him an easy target for Axe to initiate on, and kill.
* Counter Helix will trigger from, and destroy many of Terrorblade illusions.

* Broodmother's Insatiable Hunger and Troll Warlord's Battle Trance can nullify Sunder.

* Heroes with mediocre health pools who rely on armor or evasion to survive fights such as Troll Warlord, Windranger, and Terrorblade can be killed by Zeus if caught off guard.

* Static Field automatically hits everything in a big radius, taking a huge chunk of health out of Terrorblade's illusions, regardless of how much health they have.

* Terrorblade and his illusions deal huge damage, which might used against him and his team with Winter's Curse.

* Heroes who can negate effects of Sunder: Abaddon, Faceless Void, Weaver.

* Heroes who rely on skills to become a heavy hitter in a certain amount of time can waste their timing because of a lucky Lucky Shot's disarm: Terrorblade, Sven, Clinkz, Windranger, Alchemist, Dragon Knight, Legion Commander

* Mana Void deals heavy damage after Chaotic Offering and interrupts Upheaval.

* Terrorblade has a high base armor, and relies on many ultimate orb-based items (Manta Style and Eye of Skadi). Natural Order affects armor gained from agility, essentially reducing armor to zero if all armor is gained from agility. That effect combined with Terrorblade's low health can make a Elder Titan with an early value point in Natural Order a dangerous foe.
