Shadow Fiend/Counters

Bad against...

 * Sniper has a great nuke potential with his long range attacks and the Headshot skill and can also cancel blink dagger with his Shrapnel, and his ult can do a lot of damage. However you can easy kill him with an invisibility source is not a big threat against you in the middle lane but in team-fights is very annoying.


 * Zeus also have a very good nuke, which is good against Shadow Fiend in the middle lane, he can take off half of your HP with his Lightning Bolt skill as well as see invisibility, he can spam his Arc Lightning to farm and do damage to you as well.


 * Shadow Fiend has a huge lack of mobility, in which Disruptor can explore and easily gank Shadow Fiend with his Glimpse and Static Storm skills. Along with any hero that can do a some amount of damage, Shadow Fiend is pretty much dead. And if he has an aghanim, Shadow Fiend won't be able to activate your bkb, which is the only item that can help him from Disruptor.


 * All of Bane's skills can be used to hinder your game. His first skill, Enfeeble, can prevent Shadow Fiend to farm or do damage to his opponents. His second skill, Brain Sap, is a great nuke against him and, like Zeus, can easily take off Shadow Fiend's HP. His third skill, Nightmare, enables Shadow Fiend to be easily ganked and can take him off the Team Fight. And his Ult, Fiend's Grip, can kill Shadow Fiend and, even if it doesn't, probably a teammate around him will finish Shadow Fiend off.


 * Probably the worst enemy Shadow Fiend can have. First of all, her Refraction can prevent Shadow Fiend from doing any damage at all, it can take the damage from Shadow Fiend's nuke skills as well as 3 hits more. Her Meld can be used to remove your armor and kill you with few hits. Her Psi Blades are probably the best way to remove Shadow Fiend's HP while he is in lane. And her ult can damage Shadow Fiend's mobility even more.

Others

 * Ursa Fury Swipes can kill him in short time and Enrage make it quicklier without Ursa injuring.

 * Viper


 * Arc Warden can call his Tempest Double to kill Shadow Fiend and spam his all items and skills. Even he is invisible, Necronomicon will reveal him.


 * Axe's Berserker's Call can catch Shadow Fiend in the creep wave of the midlane, and Counter Helix will diminish Shadow Fiend's health rather quickly, Battle Hunger can harass Shadow Fiend early on when his Right-Click damage is very low. Culling Blade can kill Shadow Fiend quickly because of his low health pool.
