* As long as Batrider is under the effect of Firefly, he can safely fly over Proximity Mines (He does not receive vision over the mines).

* Rage protects Lifestealer from all of Techies' magic damage and disables and dispels Stasis Trap's debuff .
* Usually teams will have a hard time pushing high-ground against Techies, but Lifestealer can just pop Rage and walk uphill without fear of Techies.
Additional:
* Lifestealer's Rage lets him clear Remote Mines and Proximity Mines with proper vision.

* Rage, acting as a pseudo-Black King Bar, completely negates Mars' initiation if used in time.

* Rage protects Lifestealer from all of Lina's abilities (except an upgraded Laguna Blade).
* Open Wounds is great to keep Lina in place because she has no abilities to help her escape.

* Heroes who can slow and kite Axe will severely inhibit his presence in fights: Bristleback, Crystal Maiden, Batrider, Arc Warden, Winter Wyvern, Clockwerk

* Feast's lifesteal makes it nearly impossible for Axe to initiate and bring Lifestealer's health low enough for Culling Blade, even with many procs of Counter Helix.
* Feast's healing is calculated as a percentage of a target's max health, turning Axe's high health against him. This allows Lifestealer to trade against Axe much better than most other heroes.
Additional:
* Feast makes it impossible to put Lifestealer's health for a Culling Blade and also deals high damage to Axe due to his naturally high health.
* However, Lifestealer's Rage can be pierced by Berserker's Call.

* Batrider's DoT spells are also good versus Living Armor,

* Feast will deal a large amount of damage to Tiny's large health pool.
* Rage protects Lifestealer from Tiny's magical burst damage.

* Feast deals damage and heals Lifestealer based on the target's maximum HP, which is greatly effective against naturally high HP heroes such as Doom.
* Rage allows Lifestealer to become spell immune to negate the magical damage of Infernal Blade and Scorched Earth.
* Doom has no effective means of escape from Open Wounds. This is particularly devastating in lane, where Doom may have to play a much more passive, conservative play style as a result.

* Lifestealer's Rage renders him immune to all of Marci's disables and magic damage for a good duration.
* His passive Feast deals bonus damage based on the enemy's max health and heals for the same amount. As a tanky Strength hero, Marci's own strength will be her undoing as well.

* The lifesteal of Feast scales accordingly to the health of its target, which is effective against Pudge due to his high health and further health granted by stacks of Flesh Heap.
* Lifestealer can activate Rage to completely immune to spell, therefore rendering the damage of Rot null.
* Pudge's plentiful health makes him an ideal target for Open Wounds.

* Feast is an effective tool against Centaur Warrunner, who generally has high health and low armor, and compensates the reflected damage of Retaliate.
* If activated, Rage protects Lifestealer from Hoof Stomp, Double Edge, and Stampede.

* Rage ignores all of Viper's magical damage, although Viper Strike can pierce spell immunity and slows him down.

* Ogre's as hero with great durability and high health is great target for Lifestealer in any stage of the game, thanks to Feast.
Additional:
* Ogre Magi has nothing against Rage and his high health pool amplifies Feast.

* Rage grants Lifestealer immunity to all of Jakiro's spells. Note: magic resistance will not dispel the attack speed slow effects from Dual Breath and Liquid Fire.

* In general, heroes with spell immunity abilities won't be caught inside by Pit of Malice: Juggernaut, Lifestealer.

* Juggernaut and Lifestealer have abilities (Blade Fury and Rage respectively) that prevent Crystal Maiden from using her spells on them in the early game, before Black King Bar and other magical reduction is even an issue.

* Batrider's abilities are designed to deal damage over time, burning through Templar Assassin's layers extremely quickly. Flamebreak applies 7 instances of damage, burning through the entirety of Refraction, and Firefly applies damage on the place, forcing her to either get out of Meld and be attacked or stay in place or be incinerated.
* Flaming Lasso pierces Black King Bar and rendering Templar Assassin helpless unless there are allies helping her.
