Luden’s Echo

What is Luden’s Echo? ⚡

Luden’s Echo is the burst-on-first-cast AP item for poke mages and mobile ability-spammers — a legendary mage item whose ECHO passive converts the first ability hit in each engagement into bonus magic damage that fires orbs at nearby enemies simultaneously. The item rewards mages who open fights with high-damage abilities (Syndra Q, Lux Q, Xerath Q) by converting that opening cast into an AoE spread of orb damage to multiple targets, not just the primary.

The ECHO passive functions as a cooldown-gated burst amplifier: the 6 Echo stacks fill passively and the next ability damage that hits an enemy consumes all of them, dealing 75 (+5% AP) bonus magic damage to the primary target plus launching orbs at additional enemies within 600 units. Against a lone target, the unfired orb charges deal additional damage to the primary instead — the passive never wastes stacks, routing all unconsumed secondary damage back to the main target for a total bonus of 90–150 magic damage at the top end.

At 2,750 Gold, Luden’s Echo is priced among the more expensive AP legendaries but provides the highest base AP stat of any non-Rabadon’s item at +100 AP alongside +600 mana and +10 AH. It builds from Lost Chapter and Hextech Alternator with a 450g combine. The predecessor concept (Luden’s Companion) was a prior version; the current Echo iteration builds and plays differently. Sell price: 1,925 Gold. ID: 6655. Available on SR 5v5, ARAM, Nexus Blitz, and Arena.

⚡ ECHO Passive — Complete Mechanics Reference

Stack Generation and Consumption

ECHO generates 6 stacks passively. The stacks build immediately and are available at item purchase — the 12-second cooldown governs how frequently the full 6-stack burst can be re-triggered, not how fast stacks accumulate. When ability damage from the holder deals damage to an enemy champion or monster, all 6 stacks are consumed simultaneously, regardless of how many are currently built. This is an all-or-nothing consumption — partial stacks cannot be used.

The 12-second cooldown begins when stacks are consumed. During the cooldown, stacks rebuild to full before the cooldown expires — the next ability cast after the 12 seconds fires a full 6-stack ECHO burst again. The pattern is: cast ability → ECHO fires (6 stacks consumed) → 12-second window → cast next ability → ECHO fires again. At +10 AH on the item, the champion’s overall ability cycle is reduced but ECHO’s cooldown remains fixed at 12 seconds.

ECHO — Full Mechanics Table

Secondary Orb Mechanics — AoE Spread vs Solo Target

The secondary orb mechanic is the defining AoE feature of ECHO: each of the 5 stacks beyond the first fires one orb at a separate nearby enemy within 600 units. This means the ECHO burst can hit up to 6 total champions simultaneously — the primary target taking the base 75 (+5% AP) damage, and up to 5 additional nearby enemies each taking one orb’s worth of bonus damage.

The 600 unit auto-targeting range is roughly equivalent to the attack range of long-range champions or just outside standard melee range. Against clustered teamfights where 4-5 enemies are grouped near the primary target, ECHO fires 5 orbs outward from the primary impact point, dealing a meaningful splash of bonus magic damage to the entire cluster. Against spread formations where enemies aren’t within 600 units, the secondary stacks overflow back to the primary for higher single-target damage.

The overflow damage timing is sequential, not simultaneous: 0.25 seconds per remaining charge, delivered in order. Against a solo target with all 5 secondary stacks overflowing: damage resolves over 1.25 seconds in five separate 0.25-second intervals after the initial 75 damage. This is relevant for burst combo timing — the full ECHO damage is not instant on a solo target; the overflow portion streams in over the following 1.25 seconds.

🗺️ Map-Specific Differences

🎯 When to Build Luden’s Echo

Luden’s Echo performs best on poke mages and burst mages who open fights with one high-damage ability that triggers ECHO at range, then follow up. The 12-second ECHO cooldown aligns with the cooldown pattern of many mid-tier AP abilities — one ECHO per ability rotation.

✅ Build Luden’s Echo When:

• Champion has a long-range, single-target burst ability as primary damage: Lux Q (snare + ECHO at 1,300 range), Syndra Q (ECHO fired at safe distance), Xerath Q (ECHO at extreme range), Veigar Q (ECHO + ability damage) — ECHO fires immediately on the ability hit at range, before the target can respond
• Champion wants to poke in lane before all-in: ECHO converts every poke ability into a burst that also potentially hits nearby minions with secondary orbs, enabling both poke damage and some wave presence. The 12-second cooldown matches poke cadence — one ECHO per meaningful poke window
• Team has no source of AoE magic damage spread: ECHO’s 600-unit secondary orbs provide a burst of magic damage to clustered enemies on each proc — useful against fight-grouping compositions that bunch near the primary target
• Champion wants AP + mana with burst amplification: at +100 AP and +600 mana, Luden’s Echo has the highest base AP of any mana-sourced AP legendary. The mana supports sustained ability use for lane mages who burn through mana aggressively

❌ Do NOT Build Luden’s Echo When:

• Champion’s primary damage is sustained DoT rather than single-cast burst: Cassiopeia (Twin Fang spam), Ryze (ability weaving) — ECHO fires on the first cast then is on cooldown for 12 seconds through the sustained rotation. Blackfire Torch (DoT on every ability) or Malignance (ultimate empowerment) provide better sustained damage contribution for ability-spammers who cycle abilities every 1-3 seconds
• Enemy primary target runs Banshee’s Veil or Edge of Night: ECHO is blocked by spell shields — if the primary assassination target has Banshee’s Veil active, the ECHO burst is absorbed entirely. In that scenario, Luden’s Echo loses its burst amplification for that opening cast. Plan around breaking the shield with a lower-priority ability before the primary burst ability
• Champion deals primarily sustained magic damage from DoT abilities: ECHO’s 12-second CD means the passive fires only once per rotation window, not on every tick. Champions who deal most of their damage through persistent on-hit, DoT, or rapid multi-cast effects lose the efficiency advantage of ECHO vs items that scale with every ability cast

👥 Best Champions for Luden’s Echo

✅ Ideal Picks

• Lux — Light Binding (Q) at 1,300 range fires ECHO immediately — the initial Q snare + ECHO burst deals significant damage before the target can respond. Lucent Singularity (E) detonation as the second ability in the pattern may trigger ECHO again in the same rotation (12s CD allows it if Q-E-R sequencing is timed appropriately). Final Spark (R) at 1,300+ range can serve as an opener for a second ECHO proc in extended fights. The +100 AP also amplifies all of Lux’s ratios significantly.
• Syndra — Dark Sphere (Q) spam generates ECHO procs at range during the laning phase — ECHO fires immediately on each Q hit after the 12-second CD. Force of Will (W) throw and Scatter the Weak (E) as follow-up abilities don’t restart ECHO’s CD — only the Q opener does. Against clustered teamfights, ECHO fires orbs at nearby enemies when Q hits the primary target, spreading burst damage across the grouping.
• Xerath — Arcanopulse (Q) at 1,500 range triggers ECHO at safe poke distance — the secondary orbs spread 600 units from the Q impact point to any nearby clustered enemies. Xerath’s entire poke pattern (Q, W, E) revolves around maximum range ability use; ECHO fires on the first Q hit and recharges for the next poke window 12 seconds later. The +600 mana keeps Xerath’s aggressive Q poke pattern mana-neutral for longer.
• Veigar — Event Horizon (E) cage into Primordial Burst (R) is a fixed sequence — ECHO fires on the first ability that deals damage (usually Baleful Strike Q chip, or the R itself if R is the opener). Against a caged target, the ECHO proc in the combo plus Veigar’s enormous AP ceiling at late game produces one of the game’s highest single-cast damage totals. The +600 mana sustains his Q farming pattern without needing additional mana items.
• Orianna — Command: Attack (Q) ball throw triggers ECHO on impact — the secondary orbs spread outward from the Q landing position to nearby enemies, making Orianna’s ECHO particularly AoE-effective since her Q is typically aimed at enemy clusters in teamfight positioning. Command: Shockwave (R) can trigger a second ECHO within the same fight if the 12s CD elapsed since the Q opener.
• Vel’Koz — Plasma Fission (Q) split fires trigger ECHO on the primary Q hit — the secondary orbs benefit from the 600-unit auto-targeting around the Q impact point. Vel’Koz’s RESEARCH PROGRESS (P) true damage stacks off every ability hit, and ECHO’s initial proc fires on the first ability, potentially setting up a RESEARCH PROGRESS proc earlier in the combo chain. The +100 AP amplifies all of his ratios substantially.

Situational Picks

• Corki (Arena specifically) — Arena Luden’s Echo scales with 6% bonus AD in addition to AP, making it viable on Corki who deals mixed AP/physical damage from his abilities. The 6-second Arena CD means ECHO fires every other ability cast for rapid burst cycling. Outside Arena, Corki typically builds Manamune + AD items; Luden’s is only recommended in Arena where the AD scaling bonus activates.

❌ Less Optimal

• Ryze, Cassiopeia (sustained rotation mages): the 12-second CD provides one ECHO proc per rotation window, not on every ability. Blackfire Torch (DoT on ALL abilities, no CD limit) and Rod of Ages (scaling HP/mana/AP over time) provide better sustained rotation mage value than Luden’s single-per-rotation burst proc.
• AP support (Lulu, Soraka, Janna): ECHO fires on ability damage to enemies — support abilities that primarily apply CC or healing don’t trigger ECHO efficiently. AP damage-dealing supports (Zyra, Brand, Karma) can benefit, but pure utility supports gain minimal ECHO value.

6. Void Staff — Fifth item — 40% magic pen for MR-stacking tanks; ECHO’s 6-10% AP ratio gains full benefit of magic pen against reduced effective MR; essential for late-game vs armor/MR tanks

Veigar — Infinite AP + ECHO Scaling

7. Lost Chapter — First back — mana sustain for Baleful Strike (Q) farming rotation; Veigar burns mana rapidly in lane without mana items
8. Luden’s Echo — First full item — +100 AP immediately amplifies Veigar’s damage at a point where base AP is low; +600 mana keeps Q farming viable; ECHO fires on Q or E opener in combo
9. Rabadon’s Deathcap — Second item — MAGICAL OPUS 30% multiplier; stacks multiplicatively with Veigar’s infinite Phenomenal Evil (P) AP; Luden’s ECHO AP ratio scales with full amplified AP total
10. Zhonya’s Hourglass — Third item — STASIS during Event Horizon cage; Veigar’s vulnerability during E-R combo window; Zhonya’s enables safe R cast after ECHO fires on E opener
11. Void Staff — Fourth item — 40% magic pen; against late-game tanks Veigar’s AP ceiling and ECHO proc both benefit from pen; Phenomenal Evil stacks make ECHO AP ratio scale toward late-game breakpoints
12. Shadowflame — Fifth item — execute pen below 35% HP; ECHO fires early in combo and forces target toward 35% HP threshold where CINDERBLOOM activates on the R finisher

❌ Common Mistakes & How to Avoid Them

• Expecting ECHO to trigger Electrocute, Arcane Comet, or Conqueror: ECHO is proc damage — it explicitly does not trigger spell effects. Neither the primary 75 (+5% AP) hit nor the secondary orbs count as ability damage for rune proc purposes. Many players assume ECHO amplifies Electrocute setups — it does not. ECHO is supplementary damage on top of ability damage, separate from the rune proc calculation.
• Not considering Banshee’s Veil or Edge of Night on the primary target: ECHO is blocked by spell shields, unlike HATEFOG (Malignance). Against a primary target with Banshee’s Veil active, the ECHO burst is absorbed by the shield — the first ability cast that would have triggered ECHO is wasted. Break the spell shield with a lower-priority ability (Lux’s auto-attack, a low-CD ability) before the primary burst ability to ensure ECHO fires on the meaningful hit
• Building it on sustained DoT rotation mages: Cassiopeia, Ryze, and Anivia deal most of their damage through rapid multi-cast ability sequences that fire every 0.5-1 seconds. ECHO has a 12-second CD — it fires once per 12 seconds regardless of how many abilities are cast. Blackfire Torch (BALEFUL BLAZE on every ability cast, no CD) provides dramatically more sustained damage amplification for these patterns at comparable cost.
• Forgetting overflow timing on solo target: against an isolated target, ECHO’s 5 secondary stack overflow resolves over 1.25 seconds in 0.25-second intervals — not instantly. In a burst combo pattern against a solo target, the full ECHO damage isn’t dealt in the opening ability hit; the overflow portion streams in during the next 1.25 seconds. Time follow-up abilities accordingly — the overflow may push the target to lower HP, enabling an execute pattern that wasn’t apparent from the initial ECHO hit.
• Buying Luden’s Echo when the enemy primary target has Edge of Night: Edge of Night ANNUL spell shield is a component-level spell shield that regenerates. Against an ADC who built Edge of Night, the ECHO proc on the first ability targeting them is absorbed. In this matchup, Shadowflame (no shield interaction) or Void Staff (magic pen on all subsequent damage) provide better efficiency until the shield is broken by a non-triggering poke

✅ Best Practices

• Buy Lost Chapter first every game (~1,200g): MOMENTUM mana restore immediately addresses mana problems in lane; the component path directly builds into Luden’s Echo with the addition of Hextech Alternator + 450g combine
• Break spell shields before the primary ECHO ability: against Banshee’s Veil targets, use a low-priority ability (auto-attack, a non-primary ability) to consume the spell shield before the opening burst ability fires — ECHO will then trigger on the unshielded primary ability
• Use poke abilities at max range for ECHO: ECHO fires on the first ability damage hit; staying at max range (Q for Lux/Xerath, etc.) fires ECHO at safe distance before the enemy can respond, then orbs auto-target nearby clustered enemies within 600 units of the landing point
• Pair with Shadowflame for execute synergy: ECHO procs help whittle enemies to 35% HP where Shadowflame CINDERBLOOM activates; then the follow-up ability (R finisher) benefits from both CINDERBLOOM execute pen and the target is already chunked from the ECHO burst
• In Arena: build with AD champions too (6% bonus AD scaling): Arena Luden’s Echo’s bonus AD scaling makes it viable on hybrid AD/AP champions (Corki) who wouldn’t normally consider the item; the 6-second Arena CD fires ECHO every other cast in rapid combat rounds

FAQ

Q: Does Luden’s Echo ECHO trigger Electrocute or Arcane Comet?

A: A: No — ECHO deals proc damage, which explicitly does not trigger spell effects. Electrocute requires three separate damage instances from attacks or abilities (non-proc). Arcane Comet requires an ability to hit an enemy. ECHO’s damage is supplementary bonus magic damage that does not count as an ability hit for rune trigger purposes. Plan your rune proc around the actual ability casts, not the ECHO bonus damage.

Q: Does Banshee’s Veil block Luden’s Echo ECHO?

A: A: Yes — unlike Malignance’s HATEFOG, ECHO is blocked by spell shields (Banshee’s Veil passive, Edge of Night ANNUL). When the ability that would trigger ECHO hits an active spell shield, the ECHO burst is absorbed along with the ability damage. Break the spell shield with a lower-priority ability (auto-attack, minor CC) before the primary burst ability to ensure ECHO fires on the unshielded hit. This is the primary matchup consideration for Luden’s Echo vs targets with spell shields.

Q: How much damage does ECHO deal against a solo target?

A: A: Against an isolated target with no nearby enemies within 600 units, all 5 secondary stacks overflow to the primary target for maximum single-target damage: 75 (base) + 75 (max overflow) = 150 base damage, plus 5% AP (primary) + 5% AP (overflow max) = 10% AP total. At 400 AP: 150 + 40 = 190 bonus magic damage from one ECHO proc. The overflow resolves over 1.25 seconds in 0.25-second intervals (5 charges × 0.25s each), not instantaneously.

Q: What is the difference between ECHO secondary orbs and overflow damage?

A: A: Secondary orbs fire at enemies OTHER than the primary target within 600 units. Each stack beyond the first fires one orb at one separate nearby enemy. If there are fewer nearby enemies than stacks available (e.g., only 2 enemies nearby but 5 secondary stacks), the remaining stacks that can’t find a separate target overflow back to the primary target as additional damage. Overflow damage is staggered at 0.25 seconds per remaining charge.

Q: Should I build Luden’s Echo or Blackfire Torch on Viktor?

A: It depends on playstyle. Blackfire Torch (BALEFUL BLAZE) deals DoT on every ability cast with no cooldown — Viktor’s Q+E+R rapid sequence all contribute DoT damage. Luden’s Echo fires once per 12 seconds but provides +100 AP (vs +90 on Blackfire) and +10 AH. If Viktor is played as a sustained rotation mage cycling Q-E repeatedly, Blackfire Torch’s non-CD DoT provides more damage per rotation. If Viktor is played as an R-centric burst mage, Malignance (SCORN ultimate haste + HATEFOG on R) is specifically designed for that pattern. Luden’s Echo is most accurate for Viktor variants that want the highest AP stat alongside a poke-then-follow-up ability sequence.

Q: How does ECHO interact with multi-hit abilities like Syndra R?

A: A: ECHO fires on the first ability damage instance that hits the target. For Syndra R (Unleashed Power), the first sphere contact triggers ECHO — the bonus damage fires immediately and all 6 stacks are consumed. Subsequent spheres in the same R cast do NOT trigger additional ECHO procs; the 12-second CD is already running. The secondary orbs from that first ECHO proc auto-fire at nearby enemies within 600 units of the first sphere’s impact, which in a teamfight clustered around Syndra’s target can spread significant AoE damage to 5 additional enemies.
