Quillen — Assassin Guide
Key Insights
- Ambush only crits from behind, front-on attacks deal zero crit, so every approach angle is a mechanical decision, not cosmetic.
- Crit bonus scales with every 1% of crit chance you buy, making Claves Sancti a multiplier on Ambush, not just a flat crit item.
- Decimate applies a 50% slow on every hit against the marked target and its cooldown drops each time you hit that same target.
- The marked target deals 30% less damage to Quillen, giving him a hidden durability layer in extended duels his stat page never shows.
- Assassinate grants a 40% movement speed boost in stealth and resets on kill or assist, enabling back-to-back ultimates on a two-carry backline.
Strengths
Ambush guarantees 100% crit from behind, and armor alone won't stop it.
Decimate's 50% slow and self-reducing cooldown make him impossibly sticky.
Assassinate's stealth, regen, and kill-reset let him chain kills other assassins can't.- Decimate's 30% damage reduction makes him far tankier than his items suggest.
Weaknesses
- No hard CC of his own; stuns and knockups dismantle his burst before it lands.
- Ambush crits nothing from the front; Baldum or Lumburr kill his damage identity.
- Slow pre-Soulreaver clear; early invades can erase his mid-game power spike.
- A failed Assassinate all-in leaves him an immobile dealer with no escape for seconds.
Matchups
Abilities
PAmbush
When attacking an enemy from behind, guaranteed 100% crit chance (including abilities) with 125% base damage (+0.5% damage per 1% crit chance). Attacking from the front grants no crit chance. (Max 1500 damage to non-hero targets)
1Mutilate
Quillen slashes toward the target direction 2 times, each dealing 160 physical damage (+45% Bonus AD). (Can be used while moving)
2Decimate
Quillen dashes toward the target direction and attacks enemies at the end, dealing 300 physical damage (+70% Bonus AD) and marking the target for 10s. Each attack on a marked enemy slows them 50% for 1s and reduces this ability's cooldown by 1s. Quillen takes 30% reduced damage from marked enemies. (Can mark only 1 enemy at a time)
RAssassinate
Quillen dashes forward and becomes invisible. During this time, movement speed increases 40% and restores 70 HP (+15% Bonus AD) every 0.5s for 3s. Attacking breaks invisibility and grants 150 attack power for 3s. Enemies hit by attacks take increased damage and Quillen gains 30% movement speed for 1s. Passive: Killing or assisting a kill on an enemy hero resets all ability cooldowns.

Standard Gank Burst
2P1Dash with W to land behind the target, let Ambush trigger on first contact, then Q immediately for two rear crits followed by autos with the slow keeping them in range. This is the bread-and-butter kill pattern for any isolated carry.
Stealth Re-angle Kill
2RP1Use when the target is facing you or has a gap-closer. W in to apply the mark and slow, immediately pop Assassinate to circle behind during the stealth window, then break stealth into Ambush crits with Q. The mark's slow makes sure they can't escape while you reposition.
Chain Execute
RP12ROpen with Assassinate to approach from stealth in a teamfight, burst the first target from behind with autos and Q, use W to leap onto the second carry, and if the first kill procs the Ultimate reset, activate Assassinate again immediately to cycle for a clean two-man elimination.
Objective Skirmish Disengage
21RWhen trading at Dragon or Abyssal Dragon without full kill confidence, W to apply the mark, weave Q for damage, then R to vanish and reset the engagement if the trade is going badly. The speed buff gets you out while the mark's damage reduction continues to blunt their retaliation.

Gameplan
Quillen's first spike is level 4 with all three abilities, but it only matters with Soulreaver complete. Before that item his burst is bluffable. The real breakpoint is Soulreaver plus Claves Sancti, where Ambush crits delete squishies in two to three hits from behind and ganks stop being coin flips. His second spike, often the decisive one in ranked, is Broken Spear: the armor pen lets him threaten fighters and off-tanks, widening his kill pool past pure carries. Late game he is a threat rather than a win condition, since grouped teams deny him the isolation he needs.
Early Game
Levels 1–6- →Start Red Buff side to finish your first clear quickly, prioritizing fast Soulreaver stacks. Don't invade or fight before the item is close to complete; your pre-item damage is genuinely unimpressive.
- →Gank lanes where enemies are overextended past the river midpoint. A W dash that lands cleanly behind a pushing laner is an almost-free kill at Level 4 because they have no time to turn and deny Ambush.
- →Contest enemy jungle camps after a successful gank rather than recalling. The gold from stealing a camp plus securing your own buffs speeds up Soulreaver completion by one to two waves.
Mid Game
Post Broken Spear- →With Soulreaver and Gilded Greaves complete, prioritize rotating to Dragon when it spawns. Your kill threat on any support or mage warding the objective is high enough that you can pressure the pit and duel-clear simultaneously.
- →Look for the enemy carry isolated in a sidelane. A one-item Quillen that reaches a solo ADC from behind will nearly always convert the kill, and the snowball from that repeated pressure is how you close games before the enemy team groups.
- →Build Claves Sancti before Broken Spear if the enemy team is carry-heavy. If they are running two fighters or a bruiser jungler, flip that order to keep kill pressure on non-squishies.
Late Game
Teamfight phase- →Abyssal Dragon setup is your most important macro window. Deep ward the enemy jungle thirty seconds before spawn, identify the carry's position, and use Assassinate's stealth to approach from an unexpected angle rather than walking through a chokepoint.
- →In five-on-five teamfights, never engage from the front regardless of how strong you feel. Wait for your frontline to absorb the first wave of crowd control before using W and R to access the backline. A single stun during Assassinate's exit animation kills your threat entirely.
- →If the game goes past two Abyssal Dragon stacks and the enemy has a tanky composition, accept that you are a disruptor rather than a solo winner. Pick off the support or the mage before the objective fight starts and let your team do the rest.
Pro Tips
- →During Assassinate's stealth window, circle your target using the 40% speed bonus rather than charging straight in. That extra half-second of repositioning is the difference between a guaranteed Ambush crit opener and a wasted ultimate.
- →W's cooldown reduction fires on any hit against the marked target, including Q's two slashes. Weaving Q immediately after landing Decimate refunds nearly two seconds of W cooldown in a single combo, giving you a second dash far sooner than enemies expect.
- →Track the enemy jungler's buff timers. Quillen can steal Blue or Red Buff between ganks by using the Decimate dash to gap-close onto the camp from an unexpected angle, and Punish secures the objective before anyone arrives to contest.
- →Against mobile carries who try to turn and face you mid-combo, use Assassinate as a repositioning tool rather than an opener. Pop the stealth after you've applied W's mark, let the slow do its work while you circle behind, and reappear for the kill instead of giving them the facing reset they want.
Quillen is the right jungle pick for disciplined Diamond-plus players who understand positional assassin play and want a hero that punishes enemy complacency at both the duel and macro level. He does not forgive random all-ins. His damage lives or dies on landing behind the target. Meet that condition consistently and he is one of the few junglers who can solo-decide a game's pace. The thing to master is using Assassinate not as an opener but as a mid-fight repositioning tool that fixes your angle against targets who turn to face you. Get that right and the rest of the kit clicks.
Quillen — Frequently Asked Questions
Is Quillen good in the current ROV patch?+
Yes. Quillen is firmly S tier this patch, built on punishing the many immobile carries and slow bruiser junglers who can't stop a clean rear approach. His sustain, slow, and damage reduction make him one of the most complete jungle assassins right now. If you can play him, he is one of the highest-value jungle picks at Diamond and above.
What is the best build for Quillen?+
Core path is Soulreaver into Gilded Greaves, then Claves Sancti for the crit synergy with Ambush, Broken Spear for armor pen into bruisers, Omni Arms for on-hit attack speed, and Fenrir's Tooth for an execute threshold. Don't reorder casually. Claves Sancti multiplies Ambush's bonus crit damage per 1% crit chance, making it a non-negotiable third item.
How do you counter Quillen?+
Point-and-click CC that forces him to engage from the front strips Ambush crits and turns the duel into a damage race he loses. Baldum and Arum are the problem picks because they control his approach angle. At draft level, a frontline CC support plus a mobile carry who can pre-face him on a spotted gank removes most of his kill threat.
Is Quillen hard to play / good for beginners?+
Medium difficulty. The basic combo is accessible, but landing behind targets consistently with Decimate and timing Assassinate's reposition correctly is punishing when misread. Beginners feel weak because they trigger Ambush crits inconsistently. He is a good second or third jungle hero once camp routing and gank pathing are internalized.
