What is Luden’s Echo? \u26a1<\/strong><\/h2>\n\n\n\n

Luden’s Echo is the burst-on-first-cast AP item for poke mages and mobile ability-spammers<\/strong> \u2014 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<\/strong> 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.<\/p>\n\n\n\n

The ECHO passive functions as a cooldown-gated burst amplifier<\/strong>: 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 \u2014 the passive never wastes stacks<\/strong>, routing all unconsumed secondary damage back to the main target for a total bonus of 90\u2013150 magic damage at the top end.<\/p>\n\n\n\n

At 2,750 Gold<\/strong>, 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<\/strong><\/a> and Hextech Alternator<\/strong><\/a> 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<\/strong>. ID: 6655. Available on SR 5v5, ARAM, Nexus Blitz, and Arena.<\/p>\n\n\n\n

\ud83d\udcca ECHO Damage \u2014 Full Scenario Breakdown by Target Count<\/strong>6 stacks consumed total. Primary always gets: 75 + 5% AP. Orbs fire for each stack beyond the first (up to 5 orbs). Remaining unfired orbs deal 15-75 (+1%-5% AP each) to primary.1 additional target nearby: 1 stack fires orb (0.528s delay), 4 stacks overflow to primary \u2192 primary gets 75+(4\u00d715-75) + 5% AP. One secondary gets orb damage.5+ additional targets nearby: all 5 secondary stacks fire orbs, 0 overflow \u2192 primary gets flat 75 + 5% AP; each of 5 nearby enemies takes one orb hit.Solo target (no nearby enemies): all 5 secondary stacks overflow to primary \u2192 75+75 = 150 max base damage + 5%+5% = 10% AP. Total: 90-150 (+6%-10% AP).At 500 AP, solo target: 150 + (10% \u00d7 500) = 150 + 50 = 200 bonus magic damage from one ECHO proc.At 500 AP, 5+ targets: 75 + (5% \u00d7 500) = 75 + 25 = 100 bonus to primary + 5 separate orbs at secondary targets.ECHO timing (remaining charges to primary): 0.25s \/ 0.5s \/ 0.75s \/ 1s \/ 1.25s depending on how many secondary charges overflow back to primary (1\/2\/3\/4\/5 remaining charges).<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

\ud83d\udca1 Hextech Alternator \u2014 Mid-Item With Its Own Passive<\/strong>Hextech Alternator<\/strong><\/a> (1,100g) is a pure AP component that shares the Hextech passive tree. Before completing Luden’s Echo, Hextech Alternator’s passive provides a unique effect at the component level.The 450g combine is among the lowest of any AP legendary item \u2014 most of Luden’s Echo’s cost is locked in its two components (1,200g + 1,100g). This means completing the item in one back requires 1,550g available after buying both components.Lost Chapter<\/strong><\/a> (1,200g) is the shared foundation of Luden’s Echo, Blackfire Torch, and Malignance. Buying Lost Chapter at first back is the correct path for any of these three items, as MOMENTUM mana restore on level up is active immediately.The purchase route: Lost Chapter (~1,200g at first back) \u2192 Hextech Alternator (~1,100g second back) \u2192 450g combine to complete Luden’s Echo. Achievable by 13-17 minutes depending on gold efficiency and farming pattern.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

\u26a1 ECHO Passive \u2014 Complete Mechanics Reference<\/strong><\/h2>\n\n\n\n

Stack Generation and Consumption<\/strong><\/h3>\n\n\n\n

ECHO generates 6 stacks passively<\/strong>. The stacks build immediately and are available at item purchase \u2014 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<\/strong>, regardless of how many are currently built. This is an all-or-nothing consumption \u2014 partial stacks cannot be used.<\/p>\n\n\n\n

The 12-second cooldown begins when stacks are consumed. During the cooldown, stacks rebuild to full before the cooldown expires<\/strong> \u2014 the next ability cast after the 12 seconds fires a full 6-stack ECHO burst again. The pattern is: cast ability \u2192 ECHO fires (6 stacks consumed) \u2192 12-second window \u2192 cast next ability \u2192 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.<\/p>\n\n\n\n

\u26a0\ufe0f ECHO \u2014 Critical Rules<\/strong>ECHO is PROC DAMAGE \u2014 it does not trigger spell effects (Electrocute, Arcane Comet, Conqueror, Grasp). The burst deals bonus magic damage but is not a spell proc.ECHO IS blocked by spell shields (Banshee’s Veil, Edge of Night ANNUL) \u2014 unlike HATEFOG (Malignance), ECHO respects spell shield blocks.ECHO bolts are PROJECTILES \u2014 secondary orbs fired at nearby targets can be interrupted by projectile-blocking abilities (Yasuo Wind Wall, Braum Unbreakable).All 6 stacks are consumed at once \u2014 there is no partial stack consumption. The first ability hit after the 12s CD fires all 6 simultaneously.Overflow timing is staggered: if 5 stacks overflow to primary (solo target), the total overflow damage resolves over 1.25 seconds in 0.25s intervals \u2014 not instantaneously.ECHO fires on ability damage \u2014 basic attacks do not trigger it. Pure auto-attack champions should not build Luden’s Echo for the passive.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Secondary Orb Mechanics \u2014 AoE Spread vs Solo Target<\/strong><\/h3>\n\n\n\n

The secondary orb mechanic is the defining AoE feature of ECHO<\/strong>: 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<\/strong> \u2014 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.<\/p>\n\n\n\n

The 600 unit auto-targeting range<\/strong> 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.<\/p>\n\n\n\n

The overflow damage timing<\/strong> 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<\/strong> \u2014 the full ECHO damage is not instant on a solo target; the overflow portion streams in over the following 1.25 seconds.<\/p>\n\n\n\n

\ud83d\udca1 ECHO Bolt Projectile Interaction \u2014 Yasuo, Braum, Pantheon<\/strong>ECHO’s secondary bolts are projectiles \u2014 this has critical interaction implications with projectile-blocking abilities.Yasuo Wind Wall: blocks ALL ECHO secondary bolts flying toward Wind Wall-protected targets. If Yasuo casts Wind Wall after ECHO fires at clustered enemies, bolts directed toward Wall-protected targets are consumed.Braum Unbreakable: similarly blocks ECHO projectile bolts targeting champions behind Braum’s shield.Pantheon W (Aegis Assault) in projectile-blocking stance: can intercept ECHO bolts.The primary damage (75 + 5% AP) is NOT a projectile \u2014 it’s direct damage on the ability hit. Only the secondary orbs fired at additional nearby targets are projectiles.Spell shields (Banshee’s Veil, Edge of Night): ECHO is blocked by spell shields entirely \u2014 if the primary target has an active spell shield, the ECHO burst on that target is absorbed. The secondary orbs may still fire at nearby non-shielded enemies.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

\ud83d\udca1 Arena Luden’s Echo \u2014 Fundamentally Different Item<\/strong>AP 100\u219285: \u221215 AP for all Arena-specific buffs below.AH 10\u219225: +15 AH \u2014 significantly better ability cycling for Arena’s multi-ability round format.ECHO base damage 75\u219280: +5 base damage per proc (minor buff).ECHO secondary damage changed to 35% of primary: on Arena the secondary orb damage is defined as a percentage of what the primary target takes, rather than the SR formula. At 80 + 5% AP primary and 35% secondary: each orb deals approximately 28 + 1.75% AP.ECHO cooldown 12\u21926 seconds: ECHO fires twice as frequently in Arena. In a 10-second Arena round fight, two ECHO procs are achievable rather than one. This dramatically increases the passive’s DPS contribution per round.NEW EFFECT: ECHO scales with 6% bonus AD \u2014 mixed AD-AP champions (Corki, certain hybrid Arena builds) gain additional ECHO damage from bonus AD. At 200 bonus AD: +12 bonus ECHO damage per proc.Net Arena evaluation: despite \u221215 AP, the 6-second CD effectively doubles ECHO’s damage contribution per fight. Arena Luden’s Echo is considerably stronger in DPS terms than SR.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

\ud83c\udfaf When to Build Luden’s Echo<\/strong><\/h2>\n\n\n\n

Luden’s Echo performs best on poke mages and burst mages who open fights with one high-damage ability<\/strong> that triggers ECHO at range, then follow up. The 12-second ECHO cooldown aligns with the cooldown pattern of many mid-tier AP abilities \u2014 one ECHO per ability rotation.<\/p>\n\n\n\n
