Strengths & Weaknesses
Strengths
- +Guaranteed crit from behind with Ambush passive enables burst damage that scales with crit chance
- +Assassinate provides invisibility, movement speed, and sustained healing for repositioning and extended fights
- +Decimate's slow + mark synergy enables kiting and repeated burst windows on marked targets
Weaknesses
- −Front-to-back engagements remove crit potential, forcing awkward positioning or utility role
- −High reliance on flanking positioning makes him exploitable to grouped enemies and vision control
- −Invisibility breaks on damage, requiring precise timing to maximize healing window before commitment
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.

Burst Flank
R21Use Assassinate to flank, land backside auto for guaranteed crit, chain Decimate into Mutilate sweeps. Maximize crit scaling before enemies react.
Chase & Kite
212Mark target with Decimate, alternate Mutilate sweeps and autos to trigger slow repeatedly while maintaining backside positioning for crit procs.
Reset Escape
R1If caught out, use Assassinate to gain distance and healing. Flicker + Mutilate provides additional escape vector if gank is imminent.
Gameplan
Early Game
Levels 1–6- →Farm efficiently with Mutilate while respecting enemy rotation—avoid overextending without vision control
- →Establish map pressure by invading jungle flanks; use Assassinate to scout and escape quickly
- →Accumulate gold for crit items; early crit chance multiplies your Ambush scaling significantly
Mid Game
Post Broken Spear- →Target isolated squishies (mages, ADC) in side lanes using Assassinate flanks; one rotation should eliminate them
- →Coordinate with jungler for river control and gank setups from fog of war to guarantee backside positioning
- →Maintain split-push threat while grouping for crucial objectives; your invisibility makes surprise rotations deadly
Late Game
Teamfight phase- →Position in fog of war during teamfights; never initiate into grouped enemies frontally—wait for backline positioning windows
- →Focus priority targets (ADC/mage); if fight is lost, use Assassinate to escape rather than chase kills into unfavorable terrain
- →Leverage invisibility to secure picks on isolated enemies, turning numbers advantage into objective tempo
Matchups
Quillen gets countered by
ArumHis Blessing provides group immunity during Quillen's burst window; Guard blocks Assassinate damage and CC denies repositioning.
GrakkHook catches invisible Quillen and stuns before burst combo execution; armor scales poorly against Quillen's kit.
LaurielGroup shield and heals negate burst damage; Light domain vision reveals Assassinate positioning, eliminating flank surprise.
Quillen synergizes with
- ElandorStun setup from Control guarantees backside positioning for crit procs; both excel at pick-off playstyle in coordinated rotations.
LumburrFog of war initiation with Avatar plus Quillen flank creates unbeatable 2v1 duels; crowd control chains guarantee kill pressure.
TulenBoth operate from fog of war; Tulen's area denial keeps enemies grouped while Quillen picks off stragglers for free objective conversion.
Pro Tips
- →Track enemy vision control; Assassinate into revealed areas wastes cooldown. Use ward locations to predict safe flank routes.
- →Stack crit chance over raw AD early—your Ambush passive scaling (0.5% damage per 1% crit) makes crit items mathematically superior to AD items in duels.
- →Cancel Assassinate early if you secure kills; don't waste the full 3-second healing duration if the threat has passed—rotate to next objective immediately.
Quillen thrives as a high-skill assassin in coordinated Diamond+ play where map control and positioning precision reward flanking execution. Pick into squishy, immobile teamcomps lacking grouped vision. Avoid into grouped enemies with hard CC or heroes who control space effectively.
