* Phantasm's illusions can be used to sweep Proximity Mines and Stasis Traps.
* Chaos Knight can easily kill a lone Techies before they Blast Off!.

* Lacking any stun and being heavily dependent on his physical attacks and spell immunity, Lifestealer has no way to stop Black Hole, assuming he does not initiate Enigma first with Abyssal Blade.
* Enigma's abilities, with exception of Malefice, can pierce spell immunity and deal pure damage (and percentage-based damage in Midnight Pulse's case), putting Lifestealer in potentially adverse situations.

* Heroes with summons like Broodmother,Enigma, Invoker, Nature's Prophet, Lycan, Visage;or illusions, like Naga Siren, Phantom Lancer, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity mines in the early game.

* Aside from his ultimate, Lifestealer has no AoE abilities to deal with Phantom Lancer's illusions, nor does he have the mobility to escape Phantom Rush.
* Doppelganger dispels Open Wounds.
* Phantom Lancer usually builds Diffusal Blade, which a problem for a low already mana hero like Lifestealer.
Additional:

* Phantom Lancer also commonly builds Diffusal Blade, which poses a large problem to Lifestealer and his low mana pool.

* Illusions can be sent out to destroy Techies mines.

* Refraction can be very useful in safely navigating potentially mined choke points and rune spawns.

* Heroes who can delivers a big chunk of damage in few hits will find themselves struggle against Templar Assassin's Refraction: Sven, Phantom Assassin, Ursa, Wraith King, Lifestealer

Additional:
* Techies' mines can be destroyed by Terrorblade's spammable illusions.
* Terrorblade can push without the fear of dying to mines; he can instead use his illusions to push.

* Terrorblade's illusions and ranged attacks in Metamorphosis can burst down Lifestealer very quickly.
* Terrorblade has low health due to his low strength gain, which reduces Feast's lifesteal and damage.
* Terrorblade's high armor makes Lifestealer's Desolator useless.
* Because Lifestealer usually walks around with high HP in fights due to his lifesteal (and sometimes Armlet of Mordiggian), he is a great target for Terrorblade's Sunder.
Additional:
* Reflection's illusion carries Feast as well, making it useful in fights.
* Feast cannot compensate for Terrorblade's incoming high damage, due to his low Strength gain.
* Open Wounds is a lot harder to land on the real Terrorblade if he has illusions around him.

* Heroes with summons like Broodmother,Enigma, Invoker, Nature's Prophet, Lycan, Visage;or illusions, like Naga Siren, Phantom Lancer, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity mines in the early game.

Additional:
* He can send wolves to defuse Proximity Mines, and he can catch up Techies and kill him before they can deny themselves. Even if the suicide is successful, Lycan can still survive because of his tankiness.

* Heroes with summons: Lycan, Broodmother, Visage.

* Static Link cannot be dispelled by Rage or Infest, so Razor will be able to track Lifestealer down during an attempted escape.

* Static Link can stop Open Wounds from getting any additional lifesteal, but keep in mind Lifestealer can still utilize Feast.
* Eye of the Storm penetrates the spell immunity of Rage.

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

* Heroes with summons: Lycan, Broodmother, Visage.

* Clinkz relies heavily on the physical damage provided by Searing Arrows, which completely overrides the capabilities of Rage.

* Clinkz, by nature will often build items that Lifestealer hates dealing with such as physical damage items like Desolator or Daedalus and instant silences or hexes from Bloodthorn and Scythe of Vyse.

* With Dark Ascension Night Stalker gains unobstructed vision during night-time allowing him to easily detect mines if he has a Gem of True Sight, but Night Stalker is a melee hero so he has to use Quelling Blade to safely defuse Remote Mines and Stasis Trap.
* Dark Ascension also allows Night Stalker to fly over Proximity Mines without triggering them.
* Crippling Fear is effective in stopping Techies from using Blast Off! and Void is effective in stopping them from running to the safety of their mines.

* Juggernaut can attack Remote Mines and trigger Proximity Mines while in Blade Fury.

* Ice Blast prevents Lifestealer from lifestealing and healing with Infest in fights.

* The passive armor provided by Berserker's Rage makes Troll Warlord resilient to Feast in early game.

* Battle Trance can purge Open Wounds, negating a large amount of Lifestealer's sustain in fights.

* Borrowed Time's automatic activation will help Abaddon survive a massive Remote Mines explosion; however, the damage from a single one can kill him if his HP is low enough.
Additional:
* Aphotic Shield makes it less likely for allies to be killed by mines.
* Because they explode in very short intervals, a stack of Remote Mines will always trigger Borrowed Time, making them impossible to kill Abaddon unless his resistances are lowered enough or Abaddon is affected by Break.
* Abaddon can easily dispel the long-lasting root of Stasis Trap on himself and on an ally, while at the same also providing protection against the other mines' damage.

* Lifestealer's Feast will most likely not out-heal the damage from Fury Swipes and Overpower in the early to mid game.
Additional:
* Lifestealer can't fight Ursa in any stage of the game because of his high physical damage with Fury Swipes and Overpower.

* Exorcism's ghosts will automatically clear all Proximity Mines revealed when Death Prophet walks near them, provided that the ghosts do not have a specific target at that time.

* Techies spends lots of time standing still planting stacks of Land Mines away from creep waves.
* Sacred Arrow can be used to scout hidden Land Mines among trees and at uphill places. It can also be used to catch Techies while he's planting them.
* If Techies is hit with a Sacred Arrow, he can be killed before he has a chance to use Blast Off!.
* Mirana has a high attack range to destroy his traps from a safe distance.

* Lifestealer relies on Open Wounds to slow enemies to burst them, but Windranger can use Windrun to escape through Open Wounds duration.
* Windrun and Focus Fire can easily allow Windranger to kite Lifestealer and do good amounts of damage in the process.

* Due to Reincarnation and his general tankiness he can live through at least one major Remote Mines stack or Blast Off!.
* Special mention for a bug with his Aghanim's Scepter. If enemies get killed from your mines under the effect of "Wraith Delay", they get denied instead of crediting the kill to you.
Additional:
* Wraith King is not afraid to walk into mines, whenever he goes with his Reincarnation ready.

* Since Techies' skills are all magical damage, casting Fate's Edict immediately upon hearing the warning sound from Proximity Mines and Blast Off! can render Oracle or an ally immune to the burst damage from these skills.
* If timed correctly, Remote Mines can also be countered using the same technique.
Additional:
* Fate's Edict gives 100% magic resistance, which prevents most of Techies' damage and his Fortune's End dispels Stasis Trap root.

* Plague Wards may reveal a hiding Techies. If there's a sentry nearby, they may also reveal a stack of mines hidden in a juking spot.

* Thanks to Counterspell Anti-Mage can fight Techies head on and trip multiple mines once the late game hits.

* Dark Pact can be used to remove Open Wounds.
* Shadow Dance allows Slark to attack Lifestealer for its duration without any way for Lifestealer to fight back.
* Slark commonly buys a Silver Edge, which can break Lifestealer's Feast, severely diminishing his damage output and lifesteal.

* As long as Batrider is under the effects of Firefly, he can safely fly over mines.
* Sticky Napalm also punishes low mobility heroes that like to kite, such as Techies, by lowering their turn rate dramatically. This can also potentially delay Techies' Blast Off! if Techies tries to cast Blast Off! in a direction he's not currently facing.
Additional:
* As long as Batrider is under the effect of Firefly, he can safely fly over Proximity Miness (He does not receive vision over the mines).

* Since Untouchable pierce Spell immunity, Lifestealer cannot burst her down even with Rage ; meaning she can heal herself back to full HP.

* Lifestealer's low mobility makes him easy to kite.
* Stone Gaze pierces Rage, wasting its cooldown and making Lifestealer unable to fight.

* Reverse Polarity pierces through Rage, wasting part of it's duration.

* Heroes with spell immunity can still be disabled by Fiend's Grip: Juggernaut, Lifestealer, Pangolier.

Additional:
* Fiend's Grip can disable Lifestealer through Rage.

* Heroes with high physical damage can damage Lifestealer more than he can heal: Bristleback, Clinkz, Luna,Shadow Fiend, Slardar

* In general, heroes such as Lion, Silencer, Skywrath Mage, Sven, Ogre Magi and others with reliable disables are crucial to killing Techies before they can suicide.

* Slow heroes that have a hard time escaping the Echo Stomp radius: Crystal Maiden, Pudge, Techies.

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

* In general, heroes such as Lion, Silencer, Skywrath Mage, Sven, Ogre Magi and others with reliable disables are crucial to killing Techies before they can suicide.

* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,Bloodseeker, Lifestealer, Troll Warlord

* Heroes with low health will die easily during Duels, and can be farmed for damage in the early game: Crystal Maiden, Lich, Techies, Rubick

* Heroes with high physical damage can damage Lifestealer more than he can heal: Bristleback, Clinkz, Luna,Shadow Fiend, Slardar

* Heroes with high physical damage can damage Lifestealer more than he can heal: Bristleback, Clinkz, Luna,Shadow Fiend, Slardar

* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like Lifestealer or Juggernaut or heroes that tend to pick up Black King Bar, like Sven.

* The Swarm is not blocked by Rage and can be used to lower Lifestealer's already low armor, making him even more vulnerable to physical damage.
* Shukuchi renders the Open Wounds slow pretty useless, as it gives Weaver maximum movement speed, allowing him to escape or kite around Lifestealer.
* However, Weaver is a common Linken's Sphere carrier to block and Time Lapse to dispel Open Wounds.
Additional:
* Open Wounds's slow is ignored by Shukuchi.
* Lifestealer has no other lockdown and relies on being on top of enemies; Weaver can kite him with ease.

* Lifestealer cannot use Rage, Infest or Open Wounds when affected by Smoke Cloud's silence, and Feast cannot heal him effectively because of the blind, leaving him very weak both offensively and defensively.
* Infest ganks are harder when the enemy team has a Riki, as there are often only four heroes on the map that you can initiate on.
