Quillen Counters 2026: Best Counter Picks & Builds

Quillen is a jungle assassin who specializes in ambushes. His passive Spinal Stab makes every attack and skill from behind an enemy a guaranteed crit, but frontal attacks can never crit. Skill 1 Mutilate slashes twice in a flash, skill 2 Decimate dashes in and marks an enemy for 10 seconds; every hit on the marked victim slows them for 1 second and reduces cooldowns, while the victim also deals less damage to Quillen. His ultimate Assassinate makes him roll and then go invisible for 3 seconds, gaining movement speed and healing; assists or kills on enemy heroes also reset all his skill cooldowns. Quillen’s weaknesses are that he must reveal himself at point-blank range to deal damage, he has no CC immunity, and he loses almost all his power when forced into a head-on fight. He hates stealth-detection items, hard CC and survival items the most. Counters to Quillen include Zanis, Enzo, Fennik in the Jungle, Omen in the Dark Slayer lane, Aleister, Lauriel in the Mid lane, Arum, Thane, Gildur as Support and Stuart in the Abyssal Dragon lane.

• Zanis
• Enzo
• Fennik

Zanis

Each time Quillen hits a victim marked by Decimate , the target is slowed for 1 second so he can circle behind and trigger the crit from Spinal Stab . Zanis isn’t pinned down by this kind of slow, because the passive Dragoon makes each of his skills cleanse crowd control (except suppression), letting him always turn to face Quillen. When Quillen reappears after Assassinate , Dragon Wraith locks straight onto him with a stun, slow and true damage, giving him no time to slip behind. Blood Wyrm boosts movement speed to keep chasing, while Tail Sweep grants lifesteal to survive the first burst.

Enzo

Quillen has to reappear at point-blank range to deal damage, and that’s exactly the distance where Enzo ‘s blade is least likely to miss. As soon as he dashes in with Decimate , Enzo swings Judgment to bind the first enemy hit, then uses Amputate to pull Quillen in, forcing him to stand in front instead of behind. While rooted, Quillen can’t roll away with Assassinate to go stealth and escape. If he still manages to get far away, the passive Crusade lets Enzo deal bonus damage to distant enemies, and Decapitate strikes from behind the target under Judgment.

Fennik

Stealth from Assassinate is Quillen’s main weapon, and Fennik ‘s passive Slingshot makes it far less valuable: Fennik listens for movement nearby, revealing enemies for 1 second, repeatable every 6 seconds on the same unit. When Quillen dashes in with Decimate , Electric Zap lets Fennik roll forward while untargetable, dodging and slowing him at the same time, while Supersonic Vortex creates a storm that deals damage and slows every 0.5 seconds. Constantly slowed, Quillen has a very hard time getting behind to trigger Spinal Stab .

• Omen

Omen

Quillen usually avoids sturdy heroes like Omen , but as long as Omen stands next to the marksman, every assassination attempt gets punished. When Quillen reappears, Death's Beckon pulls him in and slows him, then Death's Embrace charges in to raise a death arena: the target deals reduced damage and can’t escape for 5 seconds, so Assassinate can’t get Quillen out of the trap. If he turns to strike Omen, Untouchable increases damage reduction and reflects Quillen’s own basic attacks back at him, dealing damage and slowing.

• Aleister
• Lauriel

Aleister

Quillen has to reappear to attack, and that moment is all Aleister needs. Magic Barrier raises a barrier that stuns right where he just dashed in with Decimate , then Magic Prison locks him in a magic prison, dealing magic damage every tick for 2.5 seconds. Trapped like that, Quillen can’t roll away with Assassinate to go stealth and heal, and without a takedown he doesn’t get his cooldowns reset either. A third skill hitting the same target also detonates the passive Wicked Plot for true damage.

Lauriel

Quillen plans his assassinations around the target failing to react after the dash from Decimate . Lauriel always keeps a dash from Wings of Purity in reserve to leave the marked spot, then flaps her wings to fire 3 beams of light, each one reducing cooldown when it hits an enemy. Standing inside Great Judgment , she recovers cooldowns twice as fast and can dash continuously, making it hard for Quillen to stay behind her. Once he has used up Mutilate and Decimate , 4 stacks of the passive Heaven's Punishment detonate for true damage, heal Lauriel and slow Quillen.

• Arum
• Thane
• Gildur

Arum

Quillen’s deadliest trick is a sneak strike followed by a roll into stealth with Assassinate . Arum breaks that loop with Snare : Arum dashes in and binds the target, leaving both completely immobilized in an unbreakable link, so Quillen can’t roll or go stealth until the effect ends. Your teammates just need to pile their damage onto him. The spirit beasts circling Arum from the passive Ravenous Beasts deal continuous magic damage, and once there are 3 beasts, Uncaged stuns for 1 second right as Quillen breaks free of the bind.

Thane

Thane standing next to the marksman is enough to make Quillen think twice. The moment he reappears to strike, Valiant Charge charges in, repeatedly pushing him back and knocking him airborne at the end, shoving Quillen far away from the carry’s back. Avalon's Fury knocks up and slows a whole area, giving teammates time to burst down an assassin with no CC immunity. If Quillen turns on Thane, the passive Royal Power heals based on max HP and grants damage immunity at low HP, while Excalibur deals true damage plus 15% of the target’s missing HP.

Gildur

Quillen likes to pick off marksmen or mages standing alone, and Gildur makes that angle of approach dangerous. As soon as Quillen dashes in with Decimate or Mutilate , Indulgence sets up a magic circle that continuously deals magic damage, slows and then stuns every enemy inside; Extravagant is a second stun in case he gets out. Every time Gildur casts a skill, the shield from the passive Midas Touch helps him tank the crits if Quillen switches targets to him, while Siege dashes forward to cut off the retreat.

• Stuart

Stuart

Quillen’s skills such as Mutilate and Decimate all deal physical damage, as do the crits from behind granted by Spinal Stab . Stuart activates Blood Shadow Eye to become immune to physical damage and gain movement speed, turning an assassination that costs Quillen his whole combo into a swing at thin air. When the effect ends and Quillen has used up his skills, Destructive Blast dashes in to slow him, then Death Missile fires a straight-line projectile to finish him off. Save Blood Shadow Eye for when he reappears instead of using it early before you can see him.
