* 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.

* Heroes with weaker mobility will struggle to keep up with Night Stalker: Gyrocopter, Ursa, Drow Ranger

* Faceless Void's Timewalk allows him to backtrack any damage taken from Techies' mines. Also, he can kill Techies easily with his Chronosphere and Time Lock, preventing them from suicide. Chronosphere also reveals Remote Mines and Stasis Traps in its radius.

* Time Walk could be used to close the distance within Drow Ranger, hindering her Marksmanship bonus.
* Faceless Void could lock down Drow Ranger with Chronosphere before she has the chance to retaliate due to her low health pool.

* Shapeshift allows Lycan to get close and disable Marksmanship.
* Shapeshift also makes him immune to slows like Drow Ranger's Frost Arrows.
Additional:
* The Wolves' speed causes the knockback from Gust to be ineffective.
* She lacks escapes and loses her Marksmanship when someone is near her. Lycan takes advantage of these weaknesses.

* Drow has a very low health pool, allowing Lion to burst her down.

Additional:
* Pudge is the perfect hero for tanking mines, as Flesh Heap grants him lots of strength.
* Techies' high ground defense can be bypassed by Pudge hooking his enemies to him.

* Illusions can be sent out to destroy Techies' mines.

* Phantom Rush lets Phantom Lancer get close quickly and disable Marksmanship.
* Juxtapose's illusions are hard for Drow Ranger to deal with as she has no AoE damage naturally.

* Heroes with high physical damage output but lack of reliable escape mechanisms are always a good target for a solo gank: Sniper, Shadow Fiend, Troll Warlord, Drow Ranger. Those heroes, however, are dangerous if they manage to close the gap, so take caution.

* Magnetic Field cause attacks from Drow Ranger outside to miss, forcing Drow Ranger to go inside the field, nullifying marksmanship.

* Magnetic Field protects Arc Warden and allies from Drow Ranger's ranged attacks. She most likely will not enter the field since she will lose Marksmanship's bonus agility.

* Mirana can use Leap to jump right next to Drow Ranger or can approach her while under cover of the invisibility granted by Moonlight Shadow, which cancels the bonus granted to Drow Ranger by Marksmanship.
* Her low health makes her easy to burst down with Mirana's spells, especially with Aghanim's Scepter.
* Mirana can dodge Gust with good reaction time, or Leap away if Drow tries to slow her without Gust.

* Techies spends lots of time standing still planting stacks of Land Mines away from creep waves.

* 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.

* Due to Reincarnation and his general tankiness he can live through at least one major Remote Mines stack or Blast Off!.

* Call of the Wild Boar can clear Proximity Mines.
* The stun of Primal Roar will usually be enough to deal with the squishy Techies before they can try to suicide with Blast Off!.

* 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.

* Often you can burst Drow Ranger down before she has a chance to try and Gust you away. Try to have a teammate bait her Gust out before you Blink and get the drop on her.

* Shadow Dance lets Slark quickly close the gap and deal heavy damage without giving Drow Ranger a chance to retaliate.
* Pounce counteracts Frost Arrows' slow, letting Slark easily pin Drow Ranger down or flee.
Additional:
* Pounce and items like Shadow Blade makes it very difficult for Drow Ranger to keep her distance from Slark, thereby losing her Marksmanship bonus.
* Gust is rarely enough to keep Slark at bay, as Drow Ranger has no movement abilities and will simply be chased down afterwards.
* Drow Ranger's heavy dependence on agility also makes her significantly weaker after being drained by Essence Shift.

Additional:
* Rage protects Lifestealer from all of Techies' magic damage and disables and dispels Stasis Trap's debuff .

* 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.

* His creeps can trigger Proximity Mines and Stasis Trap, wasting them.
Additional:
* Holy Persuasion creeps can be used to clear mines.
* If Chen has an Aghanim's Scepter he can send his Ancient creeps to defuse visible Remote Mines with little risk of giving up their bounties because their magic resistance is extremely high.
