Bad against...
She is not a direct counter to you since nullifies  and she has low armor with no escape mechanism, But her pierces magic immunity as well as her high range can be advantage to kill you if you dont focus her in fights. She will most likely get a to protect herself when you use  therefore consider getting a  and attack her before she deals tons of pure damage to you.

Although he is a traditional strength hero which seems perfect for Lifestealer, but his ability slows your move and attack speed. And Lifestealer has no mobility except having a bit more move speed but his base attack time is quite high which means will cost you good amount of attack speed loss by hitting you, and worse his ultimate  pierces your  makes you less efficient in combats.

Chaos Knight has armor reduction which is a real threat for you and the ability to summon powerful illusions thanks to his ultimate, which creates up to 4 copies of himself. They take normal damage and deal full damage with a chance to crit as well, Lifestealer has no ability to deal with illusions of CK due to his single target attack kit; makes you either run away from combat or die without any chances, Avoid manfight with Chaos Knight if your team has no great AoE disables like  or, consider picking up a.

Although he is just a squishy support without any escape mechanism, his deadly ultimate completely blocks all kind of regen, lifesteal with no chance to debuff it by using infest as well. Avoid fights when you have frostbitten by his ultimate

He is quite a dirty fighter with insane mobility and his ability removes your slow as well as his ultimate  gives him 4 seconds to attack you without being attacked and his  steals your attributes and helps him gain more damage and attack speed(goes through your  ). A common carrier, which blocks  and lowers your damage output significantly. Consider having more stunners and AOE disables in your team otherwise there not much Lifestealer could do against Slark.

He lowers your armor which is already low with his and he has  which grants him maximum move speed with invisibilty(bypasses any slow)  he has way better mobility advantage and can easily kite you. Consider getting a. With a careful usage weaver is easy to kill but can be problematic in any stages of game.

Simple enough, just how you will deal with Phantom Lancer(s)? Maybe you can kill 1, or 2, but then 3 will spawn, or 4, or 5.....With the low cooldown of, he can make lot of his "other self" come to his side within seconds. On the other hand, you need more than 5 seconds to kill just one of his "other self" (if he's well farmed, of course).


 * cannot be purged off by any source of Magic Immunity. However, will prevent Bane from applying Enfeeble.

Others

 * Spectre
 * Centaur Warrunner
 * Dragon Knight
 * Meepo
 * Bristleback

Items

Good against...

 * If a Clockwerk should be foolish enough to trap you inside his, turn on and  and teach him a lesson.
 * You can easily bait a Clockwerk to hook your fragile support by hiding inside him too, turning the gank around. Be mindful of how many friends he brought with him.


 * Keep your to kill the . Don't try to kill him before as he could be trying to bait you to waste your rage, and you have no way of chasing once he s away.


 * Pudge has a high strength gain and his HP is increased step by step by gaining stacks by Flesh Heap, which Feast greatly counters this point.


 * Sven's high strength and lack of mobility apart for Warcry makes him a prime target during the early stages of the game when his escape ability lies in his stun, which can be dodged by a well timed Rage. Be careful in later stages of the match after Sven gets his Black King Bar and lifesteal items as he will be able to trade blows quite effectively.

Others

 * Nyx Assassin's all skill except Vendetta can't penetrate Rage. Nyx who doesn't build BKB or Linken's Sphere at early will Open Wounded.
 * Lion's all skill can be prevented by Rage and without spell immune item build makes Lion is other good prey for Naix.
 * Lina's all skill except Scepter Laguna Blade can be prevented by Rage but some Lina builds Eul for debuff Open Wounds.
 * Underlord's Firestorm and Pit of Malice can be prevents by Rage and his mobility making him i good target for Naox until he builds Blade Mail, Lotus Orb or Linken's Sphere

Works well with...

 * He also provides good initiation which Naix may lack with.


 * Like many others, Storm Spirit is a great ally to infest as he provides a perfect gap closer with and a follow up disable with.


 * Like many others, Spirit Breaker is a great ally to infest as he provides a perfect gap closer with and a follow up disable with.


 * An allied pudge with turned on is a good target to  giving an area slow and DPS while assimilated. Additionally, targets slowed with  are also easier targets for Pudge to.


 * If infested, riki is great for traversing the map quickly and undetected, he is also able to close the gap between lifestealer and his target as well as slow them with Smoke Bomb, which if coupled with lifestealer's Open Wounds will grant a 100% slow making the kill exponentially easier

Others

 * Any ally with a is a pretty good choice to . This also includes  and
 * In the rare case that no ally provides you with any mobility whatsoever, you may want to build your own and perhaps a  or Phase Boots to chase.
 * Both Pudge and Riki are powerful weapon to kill whole team enemy. If Pudge with Rot has putted in LS, and Riki is host. Recommend Assault Cuirass, Radiance for Lifestealer.
