Singed: The Mad Chemist

Singed is a Top lane champion released on April 18, 2009, making him one of the oldest champions in the game. Classified as a Specialist (legacy: Tank, Mage), he plays in the Top lane with occasional Jungle appearances. He is Melee with approximately 125 attack range, adaptive type Magic, using Mana. Base MS: 345.

Last changed patch V25.17. Store price: 2400 BE / 260 RP – Singed is one of the cheapest champions in RP (260 RP) reflecting his original roster status. His design philosophy is fundamentally different from every other champion in the game: Singed does not want to fight, chase, or engage conventionally. His kit rewards running away from or through enemies at maximum speed while leaving poison behind, then using Fling to reposition a single priority target into the adhesive. High-elo Singed play involves proxy farming (farming between enemy tower and their base), forcing a guaranteed 1v2 scenario where both members of the enemy team chase and feed movement speed stacks. This is a champion where understanding enemy psychology is the primary skill, not mechanical execution.

📊 Base Statistics

💡 345 Base MS – The Foundation of Everything: Singed’s 345 base movement speed is above the top-lane average (340 for most melee champions). Combined with Noxious Slipstream’s up to 625% bonus speed near champions, movement speed items, and Insanity Potion’s MS bonus, Singed at full passive stacks moves faster than any champion in the game can realistically follow. The base MS matters because every MS item and passive stack multiplies from this foundation. A 10% MS advantage compounds into an uncatchable gap over a 1000-unit chase distance.

Passive: Noxious Slipstream

TARGET IMMUNITY: 8 seconds  |  EFFECT RADIUS: 225

INNATE: Whenever Singed moves near a champion, he gains a stack of Noxious Slipstream for 2 seconds, refreshing on subsequent passes and stacking up to 25 times. For each stack, Singed gains 25% bonus movement speed, up to a maximum of 625%. This effect cannot occur on the same target more than once every few seconds.

💡 Passive as Psychological Warfare: Noxious Slipstream creates an incentive inversion – the more enemies that chase Singed, the faster he becomes. In a 5v5 where the entire enemy team chases Singed, he achieves 125% bonus movement speed from 5 stacks simultaneously while his team engages the undefended enemy backline. The enemy team faces an impossible choice: chase Singed and feed him MS stacks while losing the fight elsewhere, or abandon the chase and let Singed farm freely. There is no correct answer for the enemy team – this is the fundamental strategic power of the champion.

⚠️ 8-Second Target Immunity: Each champion provides one stack but cannot provide another for 8 seconds. Running past the same champion repeatedly does not generate continuous stacks. Against a single enemy chasing Singed in a side lane, maximum passive stacks is 1 from the chaser (not unlimited). The multi-champion stack scenario requires passing multiple different champions – ganks and teamfights provide more stack opportunities than a 1v1 chase.

Q: Poison Trail

Cost: 13 Mana per second (toggle)  |  Static CD: 1 second  |  Cast Time: None  |  Effect Radius: 180

TOGGLE: Singed continually creates a toxic cloud in his wake that lingers for 3.25 seconds. The cloud inflicts poison to enemies within. POISON: The target takes magic damage every 0.25 seconds over 2 seconds as well as upon being hit if not currently affected. Subsequent inflictions refresh the duration. Singed earns the kill credit of enemy minions that are poisoned and would die to the damage of allied minions within the time before the next damage instance.

💡 The Running Trail – Damage Without Interaction: Poison Trail’s toggle design is the most unique damage ability in the game: Singed deals damage by running, not by aiming. Enemies who chase Singed walk through the trailing poison cloud. Enemies who don’t chase take no damage. This creates the core strategic loop: enemies who decide not to chase take zero Q damage, enemies who chase take consistent Q ticks amplified by the 3.25-second persistence of the cloud. In a straight chase of 10 seconds, an enemy runs through poison cloud continuously, taking 40 ticks of 15 (+10.625% AP) damage – at 300 AP, approximately 40 × 47 = 1880 magic damage from Q alone just from chasing.

💡 Mana Efficiency Management: At 13 Mana per second, Poison Trail consumes significant Mana. At 330 base Mana (level 1), Q would deplete Mana in 25 seconds. Mana items (Rylai’s, Liandrys) and Insanity Potion’s Mana regen extend the Q uptime window. Do not toggle Q during periods where Singed is running in open space with no nearby enemies – the cloud is wasted with no targets. Toggle Q on when entering brush, approaching enemies, or initiating the run-through pattern.

W: Mega Adhesive

Cost: 60/70/80/90/100 Mana  |  CD: 17/16/15/14/13 sec  |  Cast Time: 0.25  |  Target Range: 1000  |  Effect Radius: 265

ACTIVE: Singed spills a potent adhesive that lands at the target location after 0.375 seconds, creating a field for 3 seconds that grounds enemies within and slows them.

💡 Grounded – The Dash-Cancel Effect: Mega Adhesive applies Grounded – a CC that prevents all dashes, jumps, and teleport abilities while the target is within the zone. Against mobile champions like Ezreal, Zed, LeBlanc, or Tristana, landing W completely removes their primary mobility option for 3 seconds. A Grounded Zed cannot Shadow Dash. A Grounded Tristana cannot Rocket Jump. A Grounded LeBlanc cannot use Distortion. W is hardest-countered by immobile champions who simply walk through it – it is most devastating against high-mobility assassins and ADCs.

💡 W + E Root Combo: Mega Adhesive’s strongest interaction is with Fling: if the target lands inside the W zone after being Flung, they are rooted for 1–2 seconds. The combo sequence is W (throw adhesive at predicted landing zone) → E (Fling the target into the W field) → root lands automatically. This requires anticipating where the Flung target will land (550 units over Singed in the cast direction) and placing W in that exact spot. At max rank, the root is 2 seconds – the longest duration Singed can CC a target. This is the only hard CC in Singed’s kit and requires deliberate setup.

⚠️ 0.375-Second Landing Delay: W takes 0.375 seconds to land. Against targets with burst-speed reactions, the landing delay provides a brief dodge window. In the W + E combo, time W throw to account for the delay – throw W slightly before pressing E so W lands at the same time the Flung target arrives. Throwing W simultaneously with E means W lands 0.375 seconds after the Flung target, missing the root window entirely.

E: Fling

Cost: 60/70/80/90/100 Mana  |  CD: 10/9.5/9/8.5/8 sec  |  Cast Time: 0.25  |  Target Range: 125

ACTIVE: Singed flings the target enemy 550 units over himself over 0.693 seconds, dealing magic damage. The damage based on the target’s health ratio is capped at 300 against minions and monsters. If the target lands on Mega Adhesive’s area of effect after the displacement, they are rooted for a duration.

💡 Max-HP Scaling – Anti-Tank Tool in Melee: Fling deals 6–8% of the target’s maximum health as magic damage at max rank. Against a 5000 HP tank: 8% × 5000 = 400 bonus magic damage per Fling in addition to base damage. At 300 AP: 90 + 165 AP = 255 base + 400 HP scaling = 655 magic damage from a single Fling on a high-HP target. Fling’s damage increases against tankier opponents – the same counterintuitive scaling as Sett’s W and Gnar’s R. Building HP against Singed makes Fling more lethal per cast.

💡 Fling Direction – Throw Target Behind Singed: Fling throws the target 550 units over Singed in the direction Singed is currently facing. To Fling a target away from their team and into the W field, Singed must be positioned between the target and the intended landing zone. In a gank scenario: Singed runs past the enemy laner (passive MS stack) → turns to face the enemy → W thrown toward the ally → E Flings the enemy into the W zone. The turn-face-E execution requires positioning Singed on the far side of the target relative to the intended Fling direction.

⚠️ Fling is a Melee-Range Ability: Target range is 125 units – effective melee contact range. Against champions who maintain distance (ranged champions, Ezreal Arcane Shift, Ahri Charm), Singed must get within auto-attack range before E is available. The approach is enabled by W’s slow (70% at rank 5), passive MS stacks from nearby champions, and Insanity Potion MS bonus. Against champions who kite Singed to infinite range, E never connects without W setup first.

R: Insanity Potion (Ultimate)

Cost: 100 Mana  |  CD: 100 sec  |  Cast Time: None

ACTIVE: Singed empowers himself for 25 seconds with bonus ability power, armor, magic resistance, movement speed, health regeneration, and mana regeneration. During this time, Poison Trail additionally applies Grievous Wounds for 1 second, which refreshes every 0.25 seconds while the poison persists.

💡 All-Stats Buff – Why Insanity Potion is Underrated: Insanity Potion provides all six stats simultaneously: AP, armor, MR, movement speed, HP regen, and Mana regen. At rank 3: +95 to every stat for 25 seconds. The movement speed bonus combined with Noxious Slipstream passive stacks pushes Singed’s MS to extreme values during teamfights. The armor and MR bonuses add significant tankiness during the 25-second fight window. The HP/Mana regen at 9.5 per 0.5 seconds = 19 per second = 475 HP and 475 Mana regenerated over the full duration – approximately half a Warmog’s regen value active during combat.

💡 Grievous Wounds via Poison Trail – Counter to Healing Compositions: Insanity Potion converts Poison Trail into a sustained Grievous Wounds applicator – the strongest anti-heal tool in the game. Enemies who walk through the poison cloud during Insanity Potion receive Grievous Wounds (50% reduced healing) for 1 second, refreshed every 0.25 seconds while the poison persists. Against life-steal heavy compositions (Samira, Aatrox, Draven), chasing Singed during Insanity Potion means continuous Grievous Wounds from the poison trail they run through. This turns enemy chase behavior into a healing reduction – the cost of chasing Singed during R.

⚠️ R Timing – Early, Not Reactive: Insanity Potion should be cast before engaging a significant fight or proxy farm sequence, not reactively during combat. The 100-second cooldown means R is available approximately once every meaningful teamfight. Cast R when: entering a proxy farm position (anticipating enemy response), at Dragon or Baron start when Singed intends to disrupt, or at the beginning of a side-lane push where enemy response is expected within 25 seconds. Reactive R casting wastes the first several seconds of the buff on approach rather than active combat.

🧪 Proxy Farming – Singed’s Advanced Strategy

Proxy farming is Singed’s highest-mastery playstyle, distinct from normal jungle or lane farming. It requires understanding the strategy explicitly:

💡 The Proxy Paradox: Proxy farming creates a lose-lose scenario for the enemy team. If 1–2 enemies chase Singed: Singed gains passive MS stacks (25% per chaser), Poison Trail deals damage to chasers, Fling sends a chaser into W for a root, and Singed’s team fights 4v3 or 4v2 elsewhere. If enemies ignore Singed: he freely farms the wave plus enemy jungle camps, accelerating his gold advantage while the enemies lose the wave behind their tower. There is no correct response – both choices lose.

🎯 Strategies and Gameplay Tips

Early Game (Levels 1–6)

• Toggle Q Before Engaging, Not After: Poison Trail costs 13 Mana per second continuously. Toggle Q on 2–3 seconds before expecting enemy contact – the cloud lingers 3.25 seconds after Singed passes. Running through the lane with Q constantly active before any enemy is nearby wastes Mana on empty clouds. Toggle on when approaching the enemy, toggle off when disengaging through unwarded terrain.
• Run Through, Not At, Enemies: Early game Singed trades work by running through or past the enemy, not directly into them. Running at an enemy and stopping to auto-attack surrenders passive MS stacks and gives the enemy easy damage. Running through the enemy (passive stack generated) while trailing poison cloud (3.25 seconds of damage) deals more damage per trade interaction than any standard melee trade pattern.
• Level 6 R as Proxy Entry: First Insanity Potion should correspond with first proxy attempt if the matchup allows. R’s movement speed bonus makes the initial approach to the enemy’s tier-2 tower zone survivable against most enemy jungler response times. Without R, proxy farming at level 6 without items is high-risk. With R, the 25-second buff duration covers most enemy response timings.

Mid Game (Levels 7–13)

• W Placement Anticipation: Mega Adhesive requires predicting where a Flung target will land (550 units over Singed in the facing direction). The standard setup in a gank: ally dives from one direction → Singed positions so the enemy laner’s back is toward the ally → W thrown 550 units in the direction Singed will Fling → E Flings the enemy laner into the W zone → root → ally follow-up. W must be thrown before E to account for the 0.375-second landing delay.
• Insanity Potion into Teamfights: In mid-game teamfights, Singed should cast R when the fight begins and immediately enter the enemy cluster to generate maximum passive stacks (5 stacks from 5 enemy champions = +125% MS). With R’s 25 MS bonus + W slow (70%) + Q Grievous Wounds during R, enemies caught by W cannot meaningfully pursue or escape while Singed has near-200% MS compared to their 30% remaining after the slow.
• Q Grievous Wounds in Anti-Heal Scenarios: During Insanity Potion, Poison Trail applies Grievous Wounds consistently. Against a healing-heavy enemy team (Aatrox, Samira, Soraka), activate R and run through the enemy cluster repeatedly. Every 0.25 seconds within the poison cloud refreshes the Grievous Wounds duration. A 5-second poison cloud exposure = effectively permanent Grievous Wounds applied cheaper than any anti-heal item.

Late Game (Level 14+)

• Insanity Potion as Teamfight Initiation Signal: At rank 3 R, Insanity Potion’s 95 bonus to all stats for 25 seconds transforms Singed’s durability and combat presence. Cast R as the signal for the team to engage – R’s duration (25 seconds) defines the fight window. Singed at +95 AR/MR for 25 seconds combined with passive MS stacks and Grievous Wounds on Q creates a frontliner that absorbs significant damage while denying healing to enemies who pursue him.
• Split-Push Proxy – The Late-Game Finisher: In games where Singed is ahead, proxy farming the enemy base effectively creates a permanent second front that requires the enemy to respond. If the enemy sends 2 people to kill Singed (passive stacks from 2 chasers = +50% MS), Singed’s team pushes 5v3 elsewhere. If the enemy sends 1 person, Singed and that one person effectively 1v1 while the team fights 5v4. If the enemy sends 0 people, Singed free-farms the enemy’s entire jungle and waves unmolested.
• Fling Priority Targets: In late-game teamfights, Fling priority is: (1) enemy ADC – Flinged into the team, isolated from peel, maximum HP scaling damage against their often-moderate HP pool; (2) enemy assassin diving a carry – Fling disrupts their engage and roots them in W; (3) enemy support – Fling removes peel from their ADC. Never Fling the enemy frontline tank toward Singed’s carries – this brings the threat closer rather than displacing it.

⚔️ Core Combo Guide

1. Standard Run-Through Trade: Toggle Q on (poison cloud behind Singed) → run through or past enemy → enemy walks into poison cloud trailing Singed → if enemy chases: passive MS stacks accumulate → W thrown at their path → E Fling if within 125 range → enemy lands in W zone (root) → continue running with Q active while enemy is rooted
2. W + E Root Combo: Position so the enemy’s back is toward desired Fling landing zone → W thrown to predicted landing spot (550 units over Singed in facing direction) → E Fling → W lands ~0.375s before/after (ideally before) → target rooted 1–2 seconds in adhesive → Q poison cloud refreshes during root duration
3. Proxy Farm Sequence: R cast (25-second buff begins) → enter enemy territory between tier-1 and tier-2 towers → Q toggled on (continuous poison cloud on minion wave) → E + W on any responding enemy champion → passive MS stacks from chasers → maintain circular run pattern if multiple chasers → R MS bonus makes pursuit impossible
4. Teamfight Passive Stack Maximization: R cast → run into or through enemy 5-man cluster → passive stacks: +125% MS from 5 champions → W thrown at priority target → E Fling priority target (ADC/assassin) into W → Q Grievous Wounds applies during R to all poison-touched enemies → MS advantage prevents meaningful counter-engage

❌ Common Mistakes and How to Avoid Them

• Standing Still to Trade: Singed’s damage is generated by running. Standing still to auto-attack removes passive MS generation, eliminates the poison trail behind him, and reduces him to a low-damage melee champion with poor attack speed. Never stop moving in combat – if auto-attacking feels necessary, it’s almost always better to run through the enemy instead and rely on Q ticks.
• W + E Wrong Order: E before W means the target is Flung and lands before W arrives (0.375-second delay). The root never triggers. W must be thrown first, anticipating the Fling landing location, so the adhesive is already in position when the Flung target arrives. The delay between W throw and the target arriving via E must be 0.375 seconds or less – throw W slightly before pressing E.
• Chasing Instead of Running: Singed’s passive generates movement speed when he passes near champions – this is optimized by running near them, not by turning to face and chase. If an enemy is retreating and Singed turns to chase them, both run in the same direction: no passive stacks generated, enemy is slightly faster with boots. Instead, Singed should run toward a point that forces the enemy to pursue him – generating the chase where he has the passive advantage.
• Fling Toward Ally Carries: Fling throws the target 550 units over Singed toward wherever Singed is facing. Fling while facing toward own carries = the enemy lands on the carries. Always confirm Singed is facing away from own carries when using E on a threat – the Fling direction should launch the threat toward Singed’s frontline or into the W zone, never into the protected backline.
• Toggling Q Constantly: 13 Mana per second is sustainable but not infinite. Running across the entire map with Q toggled on wastes Mana on empty cloud with no targets. Toggle Q on only when near enemies – in enemy territory, entering a fight, or running through a minion wave. Toggle off during safe retreats, objective waits, and unchallenged base-to-lane walks.

⚙️ Recommended Build and Itemization

Core Items

• Rylai’s Crystal Scepter: The most important Singed item. Rylai’s applies a 30% slow to every ability hit. Poison Trail with Rylai’s slows every enemy who walks through the cloud. This stacks with W’s 70% slow and makes escaping Singed while he trails poison effectively impossible without a dash (which W’s ground effect prevents). The AP also amplifies Q tick damage and E’s base damage.
• Liandry’s Torment: Pairs with Rylai’s for the Grievous Wounds interaction and burn amplification. Liandry’s passive increases burn damage against slowed targets (Rylai’s slow from Q qualifies). Every enemy running through Q with Rylai’s slow takes Liandry’s amplified burn on top of Q’s base ticks. The HP and AP contribute to sustained durability and Q damage simultaneously.
• Demonic Embrace: HP + AP + burn damage per second against the target. Stacks with Poison Trail and Liandry’s for multiple simultaneous burn sources on a single target. The HP amplifies Fling’s max-HP scaling on the enemy (they build HP against Singed = Fling hits harder). Singed’s own HP also benefits from Demonic’s passive burn-in (AP scales with % of Singed’s bonus HP).

Situational Items

• Warmog’s Armor: Maximum HP for Fling’s effective damage ratio (more HP on Singed doesn’t directly scale Fling, but Warmog’s HP on Singed allows more absorbed damage during proxy sequences). The Warmog’s passive HP regen between fights keeps Singed at full HP for sustained proxy farm periods without recalling. Effective in games where attrition over time is the win condition.
• Dead Man’s Plate: Movement speed stacking toward passive Noxious Slipstream thresholds. Dead Man’s Plate adds momentum-stacking MS that compounds with R’s MS bonus and passive stacks. The momentum damage on first hit after high-speed movement adds burst to E engagements. Effective against physical-damage-heavy compositions where the armor adds significant mitigation.
• Shadowflame: Magic penetration against shield-heavy compositions (Lulu, Karma, Seraphine). Singed’s Q is percentage-based magic damage that bypasses shields – Shadowflame’s magic pen further amplifies Q damage against shielded targets remaining HP after shield breaks. Combined with Liandry’s, the AP carry hybrid build deals significant magic damage at the cost of some durability.

⚔️ Counter Picks & Matchups

✅ Singed Counters

1. Nasus – Nasus’s Q farming pattern creates predictable, stationary positions that Singed can run through repeatedly for passive stacks and Q ticks. Nasus’s slow movement speed makes chasing Singed even less productive than against average opponents. W + E during Nasus’s Wither (E) removes him from the fight temporarily while Singed continues farming.

2. Malphite – Malphite’s kit is linear and predictable. Singed can run circles around Malphite’s approach, generating passive MS stacks, and Fling Malphite into W for a root that completely denies his R engage angle. Malphite cannot catch Singed without his R, and R carries a 120-second cooldown compared to Singed’s 100-second R.

3. Cho’Gath – Cho’s high HP pool makes Fling’s max-HP scaling exceptionally damaging (8% of 5000+ HP = 400+ damage per E). Cho’s moderate mobility means Singed can maintain approach distance using passive MS. W grounds Cho during his intended Rupture (Q) cast, preventing the knock-up that would otherwise catch Singed.

❌ Singed is Countered By

1. Cassiopeia – Cassiopeia’s Noxious Blast and Twin Fang pattern harasses Singed at range where his Q trail doesn’t apply. Petrifying Gaze (R) can block Singed’s run-through approach if Singed is facing Cassiopeia during the cast. Cassiopeia’s very high sustained ranged magic damage out-ranges Singed’s entire kit during the laning phase.

2. Vayne – True damage Silver Bolts (W) bypass Singed’s armor and MR scaling entirely. Tumble (Q) repositions Vayne away from Singed’s approach and W groundfield. Condemn (E) pins Singed to walls and can interrupt proxy approaches. Vayne’s high mobility and true damage scaling make every Singed run-through less effective than against armor-reliant champions.

3. Urgot – Urgot’s passive shotgun knees deal consistent physical damage at mid-range throughout the laning phase, punishing Singed’s melee approach without chasing. Corrosive Charge (Q) slows (negating Singed’s approach advantage temporarily). Disdain (E) Flings Singed away from his intended position rather than allowing the run-through pattern. Urgot can execute Singed at low HP with his R, bypassing standard tank durability.

FAQ

Q: Why shouldn’t I chase Singed?

A: Chasing Singed activates every element of his kit simultaneously: passive Noxious Slipstream generates MS stacks from the chaser (making Singed faster the more you chase), Poison Trail applies continuous damage to anyone behind him, and W + E can root the chaser mid-pursuit. The design is explicit – Singed gets stronger and faster the more people chase him. The correct play is to disengage and let Singed farm in isolation, then address his split-push or proxy with coordinated objective pressure elsewhere.

Q: What is proxy farming and when should I use it?

A: Proxy farming is farming the enemy’s minion wave between their tier-1 and tier-2 towers, forcing the enemy to spend resources killing a threat in their own base. Use it after establishing item/level advantages and with Insanity Potion available. The key requirement is surviving the inevitable 1–2 champion response from the enemy, which R’s MS bonus + passive stacks makes manageable. Proxy farming is high risk at early levels without items and R; it becomes progressively safer as Singed’s HP, resistances, and passive MS stacking scale.

Q: How do I land the W + E root combo?

A: Throw W at the predicted landing zone of Fling (550 units in the direction Singed is facing). W has a 0.375-second landing delay. The timing: throw W slightly before pressing E so the adhesive lands as or slightly before the Flung target arrives. If W and E are pressed simultaneously, W lands 0.375 seconds after the target arrives and misses the root. Practice the 0.375-second delay until it is reflexive in the combo execution.

Q: Is Singed good in solo queue?

A: Singed has a very high mastery requirement for consistent solo queue performance. His power depends on proxy timing, Fling direction discipline, W + E root accuracy, and understanding when to force enemy responses. A Singed player who does not proxy is playing a suboptimal low-damage tank. A Singed player who proxies without understanding escape patterns feeds repeatedly. At mastery level, Singed has one of the highest win rates among one-tricks because the mechanics are unusual enough that most opponents make the fundamental mistake of chasing consistently.

Q: Does Insanity Potion Grievous Wounds replace anti-heal items?A: Partially. During the 25-second R window, Poison Trail’s Grievous Wounds application is essentially permanent if enemies remain in the cloud. However, R has a 100-second cooldown – outside the R window, Singed has no Grievous Wounds without purchasing an anti-heal item. Against heavy-healing compositions, building one anti-heal item (Morellonomicon for AP Singed) supplements the R Grievous Wounds during the non-R downtime.
