* Exorcism will continuously heal Abaddon under Borrowed Time, and cannot be turned off.
* {Ability ID:Spirit Siphon|Death Prophet} will continuously heal Abaddon under Borrowed Time, for a percentage of his maximum health.

* Duel is a great initiation to kill Death Prophet before she can cast Exorcism. Furthermore, Legion Commander often builds Blade Mail and can reflect Exorcism's damage to kill Death Prophet easily.

* Legion Commander can use Press the Attack on an ally to dispel Dismember. The bonus health regeneration also partially counters the damage of Rot
* Duel can be used on Pudge whilst Rot is active, disabling toggling which may result in a lethal health drain that leaves Legion Commander with a successful duel.

* Abaddon can activate Borrowed Time to dispel Dismember; breaking the disable and potentially allowing Abaddon to escape.
* Aphotic Shield can be cast on an ally to dispel the stun of Dismember, which can make kills difficult to secure, given that Dismember is Pudge's only reliable disable.
* Pudge lacks a mobility without a Blink Dagger, causing him to be easily chased with Curse of Avernus. The silence also prevents him from toggling off his Rot.

* Borrowed Time & Aphotic Shield can dispel Venomous Gale and Poison Sting.

* Press the Attack dispels Venomous Gale and Poison Sting from Legion Commander or her teammates.
* Venomancer is an ideal target for Duel due to his lack of mobility and low starting health.

* Chen's fragility and low mobility make him an enticing Duel target.
* Overwhelming Odds and Moment of Courage can take advantage of converted creeps' numbers.
* With enough damage from Duel stacks, Legion Commander can also often kill any of Chen's unfortunate allies before he can use Hand of God.
Additional:
* Chen's frailty and low mobility make him an enticing Duel target.
* Overwhelming Odds and Moment of Courage can take advantage of converted creeps' numbers.
* With enough damage from Duel stacks, Legion Commander can also often kill any of Chen's unfortunate allies before he can use Hand of God.

* Heroes who can negate effects of Sunder: Faceless Void's Time Walk, Weaver's Time Lapse, Broodmother's Insatiable Hunger, Abaddon's Borrowed Time and Troll Warlord's Battle Trance can nullify Sunder.

* Duel's long duration prevents Terrorblade from swapping his health with Sunder.
* Overwhelming Odds deals high damage to Terrorblade's illusions.

* Aphotic Shield is a strong dispel, meaning it can save allies from Earth Spirit's stun, slow, silence, and Magnetize.

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

* 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.
Additional:
* Borrowed Time's automatic activation will help Abaddon survive a field of Proximity Mines or a Blast Off combo. However, the damage from a single mine can kill him if his HP is low enough.
* Aphotic Shield's can easily break Techies' Etheral Blade combo.

* Abaddon could punish Chaos Knight for using his Phantasm and Reality Rift combo on him with Aphotic Shield. Additionally, it provides extra protection against Chaos Knight's potential to take Abaddon down quickly.
* Furthermore, Abaddon's Borrowed Time makes it utterly impossible to burst Abaddon down, effectively reducing the amount of targets Chaos Knight can threaten by 1 for the entire game.

* Heroes with strong area damage to destroy Phantasm illusions: Axe, Ember Spirit, Legion Commander, Phoenix

* Duel pierces spell immunity and forces him to attack Legion Commander, making him unable to use Omnislash.

* In general, heroes that deal burst in multiple instances will trigger Borrowed Time and heal Abaddon for a large amount, such as Skywrath Mage, Techies, Juggernaut, Shadow Shaman, or Ogre Magi.

* Carries that can out damage Huskar will do well against him: Legion Commander, Faceless Void, Troll Warlord, Phantom Assassin.

Additional:
* Life Break is almost suicidal when used on Legion Commander, as it invites an instant Duel and Legion Commander herself is a natural Blade Mail carrier.
* Huskar's low survivability and mostly on low health makes him particularly vulnerable to Legion Commander's high physical damage.

* Huskar's damage over time gives Abaddon the opportunity to shield and heal his allies.
* Borrowed Time also makes Abaddon a hard support to gank, thus negating Huskar's early game dominance.

* Duel's long duration prevents Nyx Assassin escaping from Vendetta. With Aghanim's Scepter she can also bypasses Spiked Carapace.

* Impale and Spiked Carapace stun can be instantly dispelled by Aphotic Shield.

* Duel makes Bristleback fight Legion Commander face to face, forcing him to take full damage.
* Press the Attack dispels the slow from stacks of Viscous Nasal Goo.
Additional:
* When dueled, Bristleback will have to face Legion head on, not allowing his passive Bristleback to come into effect.

* Lion is extremely dependent on his abilities. Silences like Silencer's Last Word, magic resistance like Oracle's Fate's Edict, and dispels like Legion Commander's Press the Attack all make his abilities less effective.

* Although Finger of Death can potentially bypass Borrowed Time, Finger's delayed damage allows an Abaddon with fast enough reaction time to activate Borrowed Time and heal from Finger.
* Aphotic Shield is extremely effective against both Earth Spike and Hex, nullifying the stun or hex while preventing further damage.
* Lion's lack of escape mechanisms allows Abaddon and his allies to pursue him with Curse of Avernus.

Additional:
* Primal Roar can be instantly dispelled by Aphotic Shield.

* Overwhelming Odds deals high damage to Phantom Lancer's illusions.
* Duel's long duration prevents Phantom Lancer from using Doppelganger.

* A Dueling Drow Ranger will lose her precious Marksmanship, reduce her damage output significantly and will more likely lose that Duel.

* Overwhelming Odds's damage stacks with each enemy unit in its radius. If this hits Broodmother and a large number of spiders it can deal significant amounts of damage.
* Moment of Courage has a high chance to proc if Broodmother and all of her spiders are attacking her.
* Duel can keep Broodmother in place long enough for Legion's team to kill her.
Additional:
* Overwhelming Odds is great at killing many stacked up spiderlings, thus giving Legion Commander a large buff.
* Duel is a reliable way to lock down Broodmother, preventing her from running into the treeline.

* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, Alchemist, Dragon Knight, Night Stalker, Viper.

* Pudge, Legion Commander and Axe will make the match a living hell for you, since they are known for surprise attacks from the fog and quickly killing low HP heroes. They can also interrupt your channeling, Legion being especially problematic, as she can use Press the Attack on an ally who is hexed as well.

* Omniknight can dispel Hex or Shackles with Heavenly Grace. He can also heal teammates which you disabled. The same goes to Abaddon's Aphotic Shield .

* Moment of Courage can become hard to deal with as it doesn't cease with silence.

* Abaddon can cast Aphotic Shield on any of his allies to immediately dispel Corrosive Haze and/or the stun and the slow components of Slithereen Crush.
* All of Slardar's debuffs are also removed if Abaddon's Borrowed Time triggers.

* Duel renders Anti-Mage's escape capabilities with Blink and Counterspell useless. Blade Mail and Moment of Courage work well against Anti-Mage's relatively low health.
