Infinity Edge

What is Infinity Edge? ⚔️

Infinity Edge is the benchmark critical strike damage amplifier for ADC marksmen and crit-based fighters — the item that converts crit chance investment into maximized critical strike damage output. While other crit items focus on attack speed, lifesteal, or movement speed alongside crit chance, Infinity Edge’s defining stat is the +30% critical strike damage bonus: a modifier that raises every critical strike from the standard 200% AD to 230% AD total damage. At 100% crit chance, every single basic attack hits at 230% AD — the highest per-hit damage ceiling for auto-attack-based champions in the game.

The PERFECTION passive translates into a concrete damage formula: most champions’ total critical strike damage increases from 200% AD to 230% AD. This 30% increase in crit multiplier applies to every critical hit regardless of other items — once Infinity Edge is purchased, every crit from Runaan’s Hurricane bolts, Navori Flickerblade empowered autos, and standard basic attacks all benefit from the amplified 230% AD formula simultaneously.

At 3,500 Gold, Infinity Edge is the most expensive standard ADC legendary in the shop — the highest raw AD legendary (+75 AD) combined with the +25% crit chance and +30% crit damage makes the price reflect the maximum single-item damage amplification available for crit-based champions.

🎯 PERFECTION Passive — Complete Mechanics Reference

Critical Strike Damage — How 230% AD Works

The base critical strike damage for most champions is 200% AD — a critical hit deals double the physical damage of a regular auto-attack. Infinity Edge’s PERFECTION adds +30% critical strike damage, bringing the total to 230% AD. Every critical strike deals 2.30× the champion’s total AD rather than the standard 2.0×.

The practical implication is a 15% increase in critical strike damage compared to the base crit formula (30/200 = 15%). At 100% crit chance, this is a flat 15% increase in auto-attack DPS over the base crit formula — not accounting for the +75 AD stat also contributing to higher total AD for the formula to multiply against. The combined effect of +75 AD and +30% crit damage makes Infinity Edge the highest single-item DPS increase available for pure crit ADCs.

The 100% Crit Interaction — Maximum Value

Infinity Edge reaches its absolute maximum value at 100% critical strike chance — when every basic attack crits. At 100% crit, the +30% crit damage bonus applies to 100% of all basic attacks, converting the permanent per-hit damage from 200% AD to 230% AD on every auto. The item effectively functions as a passive 15% DPS amplifier (30/200 = 15%) in addition to the +75 AD stat.

Building to 100% crit requires four crit items including IE’s +25%: Infinity Edge (+25%) + three other 20-25% crit items. Common paths: IE + Runaan’s Hurricane (+20%) + Phantom Dancer (+25%) + Navori Flickerblade (+30%) = 100%. At 100% crit, every auto fires at 230% AD — the PERFECTION passive is fully utilized on every single hit.

Champions with Modified Crit Formulas

The wiki note states PERFECTION increases “most champions’” total critical strike damage — the qualifier “most” exists because certain champions have modified crit mechanics:

• Ashe: critical strikes DON’T deal bonus damage — instead, they double the Frost Shot slow. IE’s +30% crit damage has no attack damage amplification effect on Ashe’s crits. Ashe builds crit specifically for the slow amplification and for the +75 AD from IE, but PERFECTION’s damage bonus does not function on her basic attacks in the standard way
• Yasuo / Yone: Way of the Wanderer (P) grants 2× critical strike chance — Yasuo with Infinity Edge converts IE’s +25% into +50% effective crit chance. Yasuo’s critical strikes also have a modified damage formula; Infinity Edge interacts with it but the calculation differs from standard ADC crit
• Jhin: Whisper (P) has a unique crit formula that interacts differently with crit chance items — Jhin converts crit chance into AD via his passive rather than standard crit damage amplification

🗺️ Map-Specific Differences

🎯 When to Build Infinity Edge

Infinity Edge’s value scales linearly with critical strike chance — the higher the crit chance, the more often PERFECTION’s +30% crit damage applies and the greater the total DPS benefit. The item’s design requires a committed crit-building strategy to reach its full potential.

✅ Build Infinity Edge When:

• Already building 2+ crit chance items: at 50%+ crit chance from other items, PERFECTION applies to half of all autos — providing meaningful sustained DPS boost; at 100% crit (4 crit items total), PERFECTION is permanently active on every single auto
• Playing a primary crit ADC: Caitlyn (Headshot P crit interactions), Jinx (Q Fishbones AoE crits), Miss Fortune (Double Up Q crit + Bullet Time R), Lucian (Ardent Blaze W), Sivir (Fleet of Foot movement crit), Varus (multiple ability crits), Tristana (Rapid Fire E during crit builds) — champions whose primary damage vector is physical auto-attacks that benefit from both the +75 AD and the crit damage amplification
• Need maximum auto-attack DPS against squishy targets: 230% AD crits against 1,800-2,000 HP ADC or mage targets where the crit burst potentially one-shots or two-shots — the maximum PERFECTION value is against opponents who can be burst by the amplified crit damage output
• Fourth or fifth item in a full crit build reaching 100% crit: if three crit items have already been purchased (e.g., Navori + Runaan’s + Stormrazor at 65-75% crit), adding Infinity Edge’s +25% crit pushes to 90-100% crit and the +30% crit damage amplification becomes near-permanently active

❌ Do NOT Build Infinity Edge When:

• Playing a non-crit ADC (Ezreal, Corki, Varus full lethality, Kog’Maw AP): Ezreal’s Arcane Shift and Mystic Shot ability damage doesn’t benefit from crit chance in the same way; Trinity Force, Manamune, or Blade of the Ruined King provide more effective damage for ability-damage ADCs than IE’s crit-dependent amplification
• Building low crit chance (under 40%): at 25% crit chance from IE alone, PERFECTION applies to only 1 in 4 autos — a ~3.75% effective DPS increase from the crit damage bonus (25% of the 15% crit DPS bonus). Other damage items (The Collector for execute, Bloodthirster for lifesteal) may provide more consistent DPS when crit chance is low
• Playing Ashe when physical burst is the goal: Ashe’s crits don’t deal bonus damage (converted to double Frost Shot slow). IE is still built on Ashe for +75 AD and +25% crit (for the enhanced slow), but PERFECTION’s +30% crit damage bonus provides no attack damage amplification on her critical strikes — the item’s core passive is non-functional for its damage purpose on Ashe’s kit

👥 Best Champions for Infinity Edge

✅ Core ADC Crit Builds

• Caitlyn — Headshot (P) sixth-shot crit (or every other auto from brush). Caitlyn naturally lands guaranteed crits through her passive, making Infinity Edge’s PERFECTION amplification apply consistently. With 100% crit from a full IE + 3 crit item build, every Caitlyn auto deals 230% AD — and the Headshot empowered crit interactions compound with the higher crit multiplier. Ace in the Hole (R) deals physical damage that also benefits from the increased crit damage formula at high AD.
• Jinx — Get Excited (P) movement speed on kill + Fishbones (Q) AoE rocket attacks. Jinx’s crit build uses IE as a core item because Fishbones rocket autos can crit and deal AoE physical damage — at 100% crit, every rocket hit on the primary target and nearby targets deals 230% AD. Pow-Pow (E) minigun attack speed stacks enable rapid crit firing during the Get Excited speed burst after a kill confirmation.
• Miss Fortune — Love Tap (P) bonus damage on different targets + Bullet Time (R) ultimate. Miss Fortune’s Bullet Time fires waves of bullets rapidly — at high crit chance, Bullet Time waves crit for 230% AD per wave rather than the standard 200%. Double Up (Q) can crit and benefits from IE’s amplified crit formula. MF’s crit build (IE + Runaan’s + crit items) delivers the highest single-fight burst DPS from both Bullet Time and sustained critting during the Q CD window.
• Sivir — Fleet of Foot (P) movement speed on ability hit + Boomerang Blade (Q) + Ricochet (W) bounce attacks. Ricochet (W) autos can crit — at 100% crit, every W bounce deals 230% AD per hit, spreading amplified crit damage across multiple targets. The combination of Runaan’s Hurricane (which also bounces off multiple targets) + Sivir’s W + IE crits creates multi-target 230% AD splash damage in teamfights.
• Tristana — Rapid Fire (E) attack speed steroid. At max E stacks, Tristana fires at high AS while critting at 230% AD — the rapid-fire crit pattern delivers extremely high burst DPS during the E window. Explosive Charge (E2) stacks from multiple crit hits before detonating for bonus physical damage that also scales with AD and crits.

Unique Interactions

• Yasuo / Yone — Way of the Wanderer (P) doubles all critical strike chance. IE’s +25% becomes +50% effective crit on Yasuo, reaching 100% crit with just two crit items instead of four. Yasuo builds IE as a core item specifically for the 2× crit conversion — at full build, Yasuo crits every hit at IE-amplified crit damage. Yone shares the 2× crit mechanic with the same IE interaction.
• Tryndamere — Battle Fury (P) fury stacks that increase crit chance. Tryndamere reaches 35%+ crit chance from his passive alone — with IE, the crit chance quickly reaches levels where PERFECTION is consistently active. Undying Rage (R) guarantees survival during the build-up to a 100% crit full-rage attack that deals 230% AD.

❌ Less Optimal

• Non-crit ADCs (Ezreal, Corki, Varus AP): ability-primary damage dealers whose win condition is poke or burst from abilities rather than sustained auto-attack crits; Trinity Force or Manamune for Ezreal, Trinity Force for Corki provide more effective damage per gold for their specific ability-damage patterns
• Ashe (PERFECTION non-functional for damage): IE is still a viable Ashe purchase for +75 AD and +25% crit chance (for enhanced Frost Shot slow), but the PERFECTION +30% crit damage bonus does not amplify Ashe’s basic attack damage on crits — the item’s core passive does not provide its primary benefit on Ashe’s kit

⚙️ Recommended Build Paths

Caitlyn — Maximum Crit Burst ADC

1. B.F. Sword — First back (1,300g) — +40 AD for maximum lane pressure; Headshot proc damage scales with AD; highest AD per gold component
2. Infinity Edge — First full item (~3,500g) — PERFECTION live; +75 AD + +25% crit + +30% crit damage; every Headshot guaranteed crit at 230% AD; sets the crit damage floor for all subsequent crit items
3. Navori Flickerblade — Second item — SHADOW DANCE: physical ability CD reduction on crit; +30% crit chance → 55% total with IE; every Headshot CD reduced by crit hits; Caitlyn’s Piltover Peacemaker (Q) fires more frequently
4. Runaan’s Hurricane — Third item — WIND’S FURY: 2 additional bolt targets per auto crit; +20% crit → 75% total; bolts also crit for 230% AD in teamfights; Headshot procs from brush stack for all three bolt targets potentially
5. Phantom Dancer — Fourth item — +25% crit → 100% total crit; SPECTRAL WALTZ movement through units + ghost effect for kiting; at 100% crit every auto fires at 230% AD permanently
6. Lord Dominik’s Regards — Fifth item situational — 35% armor pen amplifies the 230% AD crits against high-armor tanks; GIANT SLAYER bonus HP scaling; physical crit damage amplified by pen is the highest damage ceiling available vs armored targets

Jinx — Late-Game Crit Carry

7. Infinity Edge — First item — PERFECTION live; Fishbones (Q) AoE crits now at 230% AD; the AoE crit spread makes the higher crit multiplier impact multiple targets simultaneously in teamfights
8. Runaan’s Hurricane — Second item — WIND’S FURY bolts spread from Fishbones rocket mode; at 100% crit, all three targets receive Jinx Fishbones AoE + Runaan’s bolt damage simultaneously; +20% crit → 45% total
9. Phantom Dancer — Third item — +25% crit → 70% total; SPECTRAL WALTZ ghost effect for movement during kiting patterns; Get Excited (P) + Phantom Dancer speed = lethal chase after kill confirmation
10. Navori Flickerblade — Fourth item — +30% crit → 100% total; SHADOW DANCE CD reduction on crits reduces Fishbones rocket CD for more frequent Q usage; at 100% crit every auto and Q cycle is at maximum PERFECTION value
11. Mortal Reminder — Fifth item situational — FATALITY group; use when enemy runs heavy healing; replaces Lord Dominik’s if GRIEVOUS WOUNDS is higher priority than armor pen

❌ Common Mistakes & How to Avoid Them

• Building Infinity Edge as the first item without other crit items planned: at just +25% crit from IE alone, PERFECTION applies to only 1 in 4 autos. The +75 AD is strong, but the +30% crit damage bonus provides only ~3.75% effective DPS increase at 25% crit (25% of 15%). The item reaches maximum value as part of a multi-crit build approaching 100% — rushing IE as a standalone crit item before building toward higher crit chance limits its passive contribution
• Confusing 230% AD with 200% × 1.30 = 260% AD: the +30% critical strike damage is an additive bonus to the base 200% formula: 200 + 30 = 230%. It is NOT a 30% multiplication of the existing 200% (which would yield 260%). This distinction matters for damage calculations — at 400 AD, the max crit hits for 920 (230% × 400), not 1,040 (260% × 400). Understanding the correct formula prevents overestimating IE’s burst output
• Building Infinity Edge on Ezreal or other ability-primary ADCs: Ezreal deals the majority of his damage through Mystic Shot (Q) and Arcane Shift (E) — ability hits that have their own scaling independent of basic attack crit chance. The +75 AD from IE is strong on Ezreal, but the +25% crit and +30% crit damage are largely wasted on a champion who rarely basic attacks and doesn’t build toward 100% crit. Trinity Force or Manamune provide more ability-relevant damage amplification per gold
• Forgetting that Ashe’s crits don’t benefit from PERFECTION’s damage component: PERFECTION does not increase Ashe’s attack damage on crits — her crit mechanic converts crit damage to enhanced Frost Shot slow. IE is still built on Ashe for the +75 AD (which increases her regular attack and ability damage) and +25% crit (for stronger slows), but the core PERFECTION passive provides zero additional physical damage on Ashe’s critical strikes
• Not reaching 100% crit in late game: building IE as second or third item without completing the crit path to 100% leaves PERFECTION’s maximum value unrealized. At 75% crit (three crit items), PERFECTION applies to 75% of autos — buying the fourth crit item to reach 100% is the single highest-value crit investment once the other three are complete, as the last 25% of crit chance converts every remaining non-crit into a 230% AD hit

✅ Best Practices

• Buy B.F. Sword at first back if possible (1,300g): highest AD component per gold; establishes lane dominance from AD advantage; direct contribution to IE’s total cost with the highest single-component value
• Build toward 100% crit in late game: Infinity Edge’s crit damage bonus reaches full value at 100% crit; plan the 4-item crit build (IE + 3 others at 20-30% crit each) and treat completing the 100% threshold as the late-game power spike target
• Pair IE with Navori Flickerblade for ability CDR from crits: SHADOW DANCE on Navori reduces physical ability CDs on crit hits; combined with IE’s PERFECTION at 100% crit, every auto fires at 230% AD while also cycling ability CDs — the dual benefit makes the IE + Navori core the best two-item crit investment for ability-using crit ADCs
• Add Lord Dominik’s Regards against armored tanks: 35% armor pen amplifies the 230% AD crits against high-armor targets; physical crit damage is reduced by armor — pen makes each 230% AD hit more effective against the tanks who stack armor; Lord Dominik’s is the primary ‘punch through armor’ addition to IE crit builds
• On Yasuo/Yone: build IE first or second — the 2× crit conversion makes it more efficient: Yasuo’s passive doubles all crit chance, making IE’s +25% function as +50% effective crit; reaching 100% crit requires only two crit items (IE + one other 50%+ source) instead of the four needed by standard ADCs; build IE early to reach the 100% threshold faster

FAQ

Q: Does the +30% critical strike damage multiply the 200% or add to it?

A: A: It adds 30 percentage points to the 200% base — the total is 200% + 30% = 230% AD per critical strike. It does NOT multiply the base 200% by 1.30 (which would be 260%). This is a critical calculation distinction. At 400 AD: a critical strike deals 400 × 2.30 = 920 physical damage before mitigation, not 400 × 2.60 = 1,040. Always use the additive formula (230% total) for damage calculations.

Q: Is Infinity Edge worth building at low crit chance?

A: A: The +75 AD has unconditional value at any crit chance level — it directly increases all physical damage (autos, abilities that scale with AD, and crits). The PERFECTION crit damage bonus, however, scales with how often crits occur: at 25% crit, PERFECTION adds ~3.75% effective DPS (25% of the 15% bonus from crit damage increase). At 100% crit, it adds 15% effective DPS. Build IE as part of a committed crit path (planning to reach 60-100% crit by mid-game) — rushing it as a standalone item without subsequent crit items limits the passive contribution significantly.

Q: Does Infinity Edge work on Ashe’s crits?

A: A: Partially — Ashe’s crits do NOT deal bonus damage (PERFECTION’s +30% crit damage bonus has no attack damage effect on Ashe crits). Her crits instead double the Frost Shot slow. IE is still built on Ashe for the +75 AD (which boosts her regular auto damage and Q Ranger’s Focus flurry damage) and the +25% crit chance (which increases Frost Shot slow frequency through more frequent critical applications). The PERFECTION passive’s damage component does not function on Ashe’s critical strikes.

Q: How many crit items do I need to reach 100% crit?

A: Standard ADCs need 4 crit items to reach 100% crit chance: Infinity Edge (+25%) + three others providing 20-25% each (e.g., Phantom Dancer +25%, Runaan’s Hurricane +20%, Navori Flickerblade +30%). Yasuo and Yone need only 2 crit items to reach 100% (their passive doubles all crit chance: IE’s +25% becomes +50%, plus one other 25% item = +50% → 100% total). Plan the full build path around reaching 100% crit, as that is when PERFECTION’s value is fully active on every single basic attack.

Q: Is Infinity Edge the best first item for ADCs?

A: It depends on the matchup and champion. IE first provides maximum raw AD (B.F. Sword component) and starts the crit build — but it doesn’t provide lifesteal (Immortal Shieldbow for survivability), on-hit damage (Kraken Slayer for tanks), or movement utility. The standard rule: build IE first when the game plan is high burst against squishy targets and the crit path is clear. Build Immortal Shieldbow first when early survivability is needed (assassin-heavy enemy). Build Kraken Slayer first when the enemy team has 2+ high-HP tanks from the start.

Q: Does Infinity Edge interact with Runaan’s Hurricane bolts?

A: Yes — Runaan’s Hurricane Wind’s Fury bolts can critically strike. At 100% crit chance with Infinity Edge, every Wind’s Fury bolt deals 230% AD per crit on its target. This makes Runaan’s Hurricane + Infinity Edge one of the strongest multi-target crit combinations in the game — each auto fires three targets with potential 230% AD crits simultaneously. The PERFECTION crit damage bonus applies to bolt crits at the same rate as primary target crits.
