For assassins whose primary kill tool is a single-use ultimate (Zed&#8217;s Death Mark, Talon&#8217;s Shadow Assault, Qiyana&#8217;s Supreme Display of Talent, Samira&#8217;s Inferno Trigger), Axiom Arc creates a direct kill \u2192 R cooldown reduction loop: kill with the R \u2192 FLUX refunds cooldown \u2192 R available sooner for the next target.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>FLUX formula \u2014 15% + (0.15% \u00d7 lethality)<\/strong> \u2014 scales with every lethality point in the build. At 18 base lethality (Axiom Arc alone), FLUX refunds 17.7% of the R&#8217;s total cooldown. In a full lethality build with 60+ total lethality, FLUX refunds <strong>15% + (0.15 \u00d7 60) = 24% per kill<\/strong> \u2014 nearly a quarter of the ultimate&#8217;s total cooldown returned on each takedown. Combined with Ability Haste reducing the total cooldown in the first place, the effective availability frequency of the R increases substantially across a multi-kill fight or split-push sequence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>Arena transformation<\/strong> is significant and unique: in Arena, FLUX is completely removed and replaced with APOTHEGM \u2014 a flat <strong>+20% increased damage on all ultimate abilities<\/strong>. Arena Axiom Arc becomes an offensive R-damage amplifier rather than a cooldown-refund tool. The two passives serve entirely different purposes \u2014 FLUX is a cooldown management tool, APOTHEGM is a damage multiplier \u2014 making Axiom Arc&#8217;s optimal usage in Arena fundamentally different from SR\/ARAM\/Nexus Blitz.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>FLUX \u2014 Complete Mechanics Reference:Base formula: <\/strong>15% + (0.15% \u00d7 lethality) of the ultimate ability&#8217;s TOTAL cooldown is refunded per kill.<strong>&#8216;Total cooldown&#8217; definition: <\/strong>the full cooldown of the R ability as determined by level and AH \u2014 not the remaining cooldown at the time of the kill. A 90-second total cooldown R with AH reduction at 40 total AH: 90 \/ (1 + 40\/100) = 64.3s effective total CD. FLUX refunds a percentage of this reduced effective total cooldown.<strong>FLUX at 18 lethality (Axiom Arc only): <\/strong>15% + (0.15 \u00d7 18) = 15% + 2.7% = <strong>17.7% total CD refund per kill.FLUX at 40 total lethality: <\/strong>15% + (0.15 \u00d7 40) = 15% + 6% = <strong>21% total CD refund per kill.FLUX at 60 total lethality: <\/strong>15% + (0.15 \u00d7 60) = 15% + 9% = <strong>24% total CD refund per kill.FLUX at 80 total lethality: <\/strong>15% + (0.15 \u00d7 80) = 15% + 12% = <strong>27% total CD refund per kill.Minimum cooldown floor \u2014 0.5 seconds:<\/strong>If FLUX would refund the remaining cooldown entirely (resetting the R to 0), the cooldown is instead set to <strong>0.5 seconds<\/strong> \u2014 not 0. FLUX cannot provide a full instant reset of the ultimate. Even if the remaining cooldown is already less than 0.5 seconds when FLUX fires, the floor is 0.5 seconds. This prevents instant R re-use chains where back-to-back kills could cycle the R within the same fight.<strong>Delayed cooldown interaction:<\/strong>If the ultimate ability does not start its cooldown immediately on cast (some R abilities have a delayed cooldown start \u2014 abilities that channel, or where the cooldown begins after effect completion), FLUX fires and the refund takes effect <strong>after the ability goes on cooldown<\/strong>. If FLUX is triggered multiple times between cast and cooldown start, each individual refund stacks \u2014 all pending refunds apply when the cooldown begins.<strong>The 3-second kill window:<\/strong>The takedown must occur within 3 seconds of the holder dealing damage to the target. This is a generous window covering most kill combos \u2014 an assassin who opens with an ability, chains the combo, and secures the kill within 3 seconds consistently triggers FLUX. Assists that don&#8217;t involve the holder directly dealing the kill blow may or may not qualify depending on the specific damage timing \u2014 the key requirement is that the holder both dealt damage AND secured the takedown within the 3-second window.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>\ud83d\udcca Base Statistics<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Statistic<\/strong><\/td><td><strong>Value<\/strong><\/td><\/tr><tr><td>Total Cost<\/td><td>2,750 gold<\/td><\/tr><tr><td>Combine Cost<\/td><td>363 gold<\/td><\/tr><tr><td>Sell Price<\/td><td>1,925 gold<\/td><\/tr><tr><td>Attack Damage<\/td><td>+55 AD<\/td><\/tr><tr><td>Ability Haste<\/td><td>+20 AH<\/td><\/tr><tr><td>Lethality<\/td><td>+18 lethality<\/td><\/tr><tr><td>Item ID<\/td><td>6696<\/td><\/tr><tr><td>Item Limit<\/td><td>Limited to 1 Axiom Arc<\/td><\/tr><tr><td>Availability<\/td><td>SR 5v5, ARAM, Nexus Blitz, Arena<\/td><\/tr><tr><td>FLUX: Trigger<\/td><td>Takedown on enemy champion within 3 seconds of dealing damage to them<\/td><\/tr><tr><td>FLUX: Cooldown refund formula<\/td><td>15% + (0.15% per 1 lethality) of ultimate ability&#8217;s total cooldown<\/td><\/tr><tr><td>FLUX: Cooldown refund at 18 leth<\/td><td>17.7% of R&#8217;s total cooldown refunded per kill<\/td><\/tr><tr><td>FLUX: Minimum cooldown floor<\/td><td>0.5 seconds \u2014 FLUX cannot fully reset the ultimate<\/td><\/tr><tr><td>FLUX: Delayed CD interaction<\/td><td>If R cooldown starts late (delayed CDs), FLUX fires after CD begins; multiple FLUX triggers stack<\/td><\/tr><tr><td>FLUX: Kill window<\/td><td>3 seconds after the last damage the holder dealt to the target<\/td><\/tr><tr><td>Arena: AD<\/td><td>45 (\u221210 vs SR\/ARAM\/NB)<\/td><\/tr><tr><td>Arena: FLUX<\/td><td>REMOVED \u2014 not available in Arena<\/td><\/tr><tr><td>Arena: APOTHEGM (replaces FLUX)<\/td><td>Ultimate abilities deal +20% increased damage<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>\ud83d\uddfa\ufe0f Map-Specific Differences \u2014 Arena<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Stat \/ Effect<\/strong><\/td><td><strong>Value<\/strong><\/td><\/tr><tr><td>Attack Damage<\/td><td>SR\/ARAM\/NB: +55 AD \u2192 Arena: +45 AD (\u221210 AD)<\/td><\/tr><tr><td>FLUX passive<\/td><td>SR\/ARAM\/NB: ACTIVE \u2014 15% + (0.15%\/leth) cooldown refund on kill \u2192 Arena: REMOVED<\/td><\/tr><tr><td>APOTHEGM passive<\/td><td>SR\/ARAM\/NB: NOT AVAILABLE \u2192 Arena: ACTIVE \u2014 ultimate abilities deal +20% increased damage<\/td><\/tr><tr><td>AH &amp; lethality<\/td><td>All modes: +20 AH + 18 lethality (unchanged)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>\ud83d\udcca Arena APOTHEGM \u2014 +20% Ultimate Damage vs SR FLUX Comparison:Fundamental design shift:<\/strong>SR Axiom Arc (FLUX) is a <strong>cooldown management tool<\/strong> \u2014 it rewards kills with faster R availability.

The two passives serve entirely different strategic roles.<strong>APOTHEGM +20% ultimate damage in Arena context:<\/strong>In Arena&#8217;s 2v2 format, ultimate abilities are often the defining burst window of each round. A +20% damage multiplier on every R cast directly amplifies the one ability that most reliably determines round outcomes. Examples:<strong>Zed R Death Mark: <\/strong>+20% on the total mark detonation damage \u2014 significant in a format where the opponent may have a full HP pool and no prior poke reduction.<strong>Talon R Shadow Assault: <\/strong>+20% on the returning blade burst damage \u2014 amplifies the assassination window.<strong>Samira R Inferno Trigger: <\/strong>+20% on the full spin damage \u2014 potentially 20% more damage across the entire R channel duration.<strong>Qiyana R Supreme Display of Talent: <\/strong>+20% on the shockwave damage \u2014 stronger AOE burst in Arena&#8217;s close-quarters fights.<strong>\u221210 AD in Arena (45 vs 55):<\/strong>The AD reduction partially offsets APOTHEGM&#8217;s damage gain \u2014 45 AD vs 55 AD means ability damage and autoattack damage from the item itself is slightly lower. However, APOTHEGM&#8217;s 20% R amplification applies to the full ability damage value (including AP scaling, base damage, and all AD\/lethality contributions), so the net damage output from R abilities in Arena is generally higher than SR on R casts despite the AD reduction.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>\ud83d\udd28 Recipe &amp; Components<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Component<\/strong><\/td><td><strong>Cost<\/strong><\/td><td><strong>Notes<\/strong><\/td><\/tr><tr><td>Axiom Arc (Total)<\/td><td>2,750 gold<\/td><td>55 AD + 20 AH + 18 lethality + FLUX (SR) \/ APOTHEGM (Arena)<\/td><\/tr><tr><td><a href=\"https:\/\/magicstark.cz\/wiki\/the-brutalizer\/\">The Brutalizer<\/a><\/td><td>1,337 gold (212 combine)<\/td><td>Glowing Mote (250g) + Pickaxe (875g) + 212 combine; +30 AD + 15 AH + 10 lethality at component \u2014 AH + lethality spike before full item; also builds into Youmuu&#8217;s Ghostblade, Black Cleaver; Brutalizer first back is the optimal path for AH that reduces R cooldown (tightening the FLUX cycle frequency)<\/td><\/tr><tr><td>&nbsp; \u2514 Glowing Mote<\/td><td>250 gold<\/td><td>AH input for Brutalizer<\/td><\/tr><tr><td>&nbsp; \u2514 Pickaxe<\/td><td>875 gold<\/td><td>AD input for Brutalizer<\/td><\/tr><tr><td><a href=\"https:\/\/magicstark.cz\/wiki\/caulfields-warhammer\/\">Caulfield&#8217;s Warhammer<\/a><\/td><td>1,050 gold (100 combine)<\/td><td>Long Sword (350g) + Glowing Mote (250g) + Long Sword (350g) + 100 combine; +25 AD + 15 AH at component \u2014 additional AH and AD; Caulfield&#8217;s also builds into Mortal Reminder, Kraken Slayer, Trinity Force; the combination of Brutalizer + Caulfield&#8217;s provides 30 AH before the final combine<\/td><\/tr><tr><td>&nbsp; \u2514 Long Sword<\/td><td>350 gold<\/td><td>AD input (\u00d72)<\/td><\/tr><tr><td>&nbsp; \u2514 Glowing Mote<\/td><td>250 gold<\/td><td>AH input<\/td><\/tr><tr><td>Combine Cost<\/td><td>363 gold<\/td><td>Low combine \u2014 almost all value is in the two AH-providing components; Brutalizer + Caulfield&#8217;s give 30 AH and 55 AD + 10 lethality before the combine adds the remaining lethality and finalizes FLUX<\/td><\/tr><tr><td>Sell Value<\/td><td>1,925 gold<\/td><td>~70% return \u2014 standard legendary ratio<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>\ud83d\udd11 Component Build Order &amp; AH Impact on FLUX:The Brutalizer first back (1,337g) \u2014 AH + lethality + R cooldown reduction:<\/strong>Brutalizer&#8217;s <strong>+15 AH immediately reduces the R&#8217;s effective total cooldown<\/strong> \u2014 which is the denominator that FLUX&#8217;s percentage refund applies to. Lower total R cooldown \u2192 smaller absolute refund in seconds, but faster natural R cycling. The combined effect: AH reduces the R&#8217;s cycle time (faster natural availability) while FLUX provides a further percentage refund on kills.

If an ultimate&#8217;s cooldown starts after effect completion (some channel R abilities, some R abilities with delayed CD start mechanics), FLUX can be triggered multiple times between cast and cooldown initiation. <strong>Each individual FLUX trigger stacks<\/strong> \u2014 all pending refunds apply simultaneously when the cooldown finally begins.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Practical example: A champion whose R has a 2-second delay before cooldown starts. In those 2 seconds, the champion kills two enemies (both within 3 seconds of dealing damage). FLUX fires twice \u2014 two separate cooldown refunds accumulate and both apply when the R&#8217;s cooldown begins.

Every successful kill within 3 seconds of R engagement triggers FLUX, refunding up to 24%+ of the R&#8217;s effective cooldown at high lethality totals. Zed&#8217;s playstyle naturally involves opening with R \u2192 kill \u2192 retreat through W shadow, meaning every R kill is within the 3-second window. Axiom Arc directly addresses Zed&#8217;s primary limitation (long R cooldown) by rewarding kills with faster R availability. The AH from Axiom Arc additionally reduces the base R cooldown, compounding with FLUX&#8217;s percentage refund. Full lethality Zed build: Axiom Arc + Youmuu&#8217;s + Edge of Night at 56+ total lethality \u2192 FLUX refunds ~23.4% per kill.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/magicstark.cz\/en\/wiki\/talon-the-blades-shadow\/\">Talon<\/a>: <\/strong>Shadow Assault (R) is Talon&#8217;s kill-pattern ultimate \u2014 100\/80\/60-second base cooldown. FLUX on Talon fires on every kill during or immediately following the R blade burst. Talon&#8217;s E wall-hop mobility means post-kill routing to a new target or objective is fast \u2014 and if the first kill&#8217;s FLUX refund brings the R close to ready, a second fight opportunity may have the R available sooner than the base cooldown suggests. At 60 total AH and level 11 (80-second base R), FLUX at 17.7% returns 8.9 seconds per kill \u2014 at high lethality builds, this increases to 12\u201314 seconds per kill.

FLUX fires for each qualifying kill within 3 seconds \u2014 in a 2-3 kill teamfight with R, multiple FLUX refunds stack. At 40+ total lethality, each kill refunds 21% of the effective R cooldown, and a 2-kill R engagement returns 42% total. Combined with Axiom Arc&#8217;s 20 AH reducing the base cooldown, Qiyana can cycle R significantly more frequently than the base cooldown suggests in kill-heavy teamfight scenarios.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/magicstark.cz\/en\/wiki\/samira-the-desert-rose\/\">Samira<\/a>: <\/strong>Inferno Trigger (R) \u2014 extremely short base cooldown (~8 seconds) but requires S-rank style stacking.

More importantly, Samira&#8217;s passive and Q\/E chain apply damage rapidly, meaning the 3-second kill window is almost always satisfied. Axiom Arc&#8217;s AH tightens Samira&#8217;s full combo cooldowns, enabling faster style-stack generation for the next R. The APOTHEGM Arena version (+20% R damage) is particularly strong on Samira \u2014 a 20% damage boost on the full spin duration.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/magicstark.cz\/en\/wiki\/nocturne-the-eternal-nightmare\/\">Nocturne<\/a>: <\/strong>Paranoia (R) \u2014 160\/130\/100-second base cooldown.

At 60 lethality (24% FLUX), 27.4 seconds returned per kill. Nocturne&#8217;s global R is the ability with the most to gain from faster cycling \u2014 each additional R usage per game creates a new gank opportunity.

APOTHEGM in Arena adds +20% to Fate Sealed&#8217;s full damage \u2014 particularly impactful as Yone R&#8217;s base damage and AD scaling benefit proportionally.

Fiora&#8217;s R creates a 5-vital hunt on the target champion \u2014 FLUX fires if Fiora kills the target during or after the R. The R&#8217;s timing often means the kill occurs well within 3 seconds of Fiora&#8217;s last damage (she&#8217;s attacking continuously during the R). AH from Axiom Arc tightens Lunge (Q) cooldown for faster vital-seek patterns, and FLUX&#8217;s cooldown refund on the kill directly accelerates the next target&#8217;s Grand Challenge availability. In split-push dueling where Fiora fights repeatedly in the side lane, FLUX accelerates R across multiple 1v1 sequences.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Situational<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><a href=\"https:\/\/magicstark.cz\/en\/wiki\/rengar-the-pridestalker\/\">Rengar<\/a>: <\/strong>Thrill of the Hunt (R) stealth hunt \u2014 130\/115\/100-second base cooldown.

Verify that the champion&#8217;s R is both the primary kill tool AND that the holder personally secures kills before purchasing Axiom Arc. On champions where the R enables kills for teammates (support engages, CC ultimates), those kills don&#8217;t trigger FLUX for the holder.<\/li>\n\n\n\n<li><strong>Misunderstanding the 0.5-second floor \u2014 expecting a full R reset on kill: <\/strong>FLUX cannot bring the R to 0 cooldown. The minimum floor of 0.5 seconds means even in a scenario where a FLUX refund would technically overshoot the remaining cooldown, the R still has 0.5 seconds left. In rapid multi-kill sequences, this prevents back-to-back instant R usage. Plan around the 0.5-second floor: after a kill, the R will be available within 0.5 seconds at minimum floor, or at the remaining CD minus the FLUX refund percentage \u2014 not at 0.<\/li>\n\n\n\n<li><strong>Ignoring the AH interaction on FLUX&#8217;s absolute second refund: <\/strong>FLUX refunds a percentage of the total (AH-reduced) cooldown \u2014 not the base cooldown. Higher AH \u2192 lower effective total CD \u2192 smaller absolute second refund from FLUX. At very high AH builds where the R is already nearly always available, FLUX&#8217;s additional refund becomes less impactful in absolute terms (though the percentage remains the same). Axiom Arc is most valuable in the mid-game when the R has a meaningful total cooldown and FLUX&#8217;s absolute second refund translates to real additional uses per game.<\/li>\n\n\n\n<li><strong>In Arena, playing Axiom Arc as if FLUX is active: <\/strong>Arena completely removes FLUX and replaces it with APOTHEGM. A player accustomed to SR&#8217;s FLUX cooldown refund on kills will not see that benefit in Arena \u2014 R cooldowns run on their normal AH-reduced timers. The Arena playstyle shifts from kill-for-cooldown-refund to maximising single R usage by 20% damage amplification. These are fundamentally different gameplay patterns \u2014 adjust accordingly when in Arena.<\/li>\n\n\n\n<li><strong>Not securing the kill personally within 3 seconds of own damage: <\/strong>FLUX requires the HOLDER to both deal damage and secure the takedown within 3 seconds. In teamfight scenarios where an ally secures the kill that the Axiom Arc holder set up, FLUX does not trigger for the holder \u2014 even if the holder dealt significant damage. FLUX is a solo carry reward mechanic: the holder must be the one who secures the takedown within their own 3-second damage window. In team-play contexts, this means prioritizing the kill-securing hit rather than passing it to allies.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>\u2705 Best Practices<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Build Axiom Arc when the R has a meaningful cooldown (60+ seconds total) and the champion is in a kill-frequent playstyle: <\/strong>FLUX&#8217;s absolute value scales with both the R&#8217;s total cooldown length and kill frequency. The highest FLUX value scenarios are assassins with 80\u2013160 second base R cooldowns (Zed, Nocturne, Talon at early levels) who secure kills consistently in split-push or gank sequences. In games where kills are rare (defensive, long teamfight-based games), FLUX triggers less frequently and the R cycling benefit is lower \u2014 consider whether the game&#8217;s kill frequency justifies Axiom Arc over alternatives.<\/li>\n\n\n\n<li><strong>Stack lethality across the build to maximise FLUX&#8217;s per-kill percentage refund: <\/strong>Every additional lethality point adds 0.15% to FLUX&#8217;s refund. At 60 total lethality (Axiom Arc + two other lethality items), FLUX refunds 24% per kill \u2014 a meaningful improvement over the 17.7% at 18 lethality alone. Full lethality builds (Axiom Arc + Youmuu&#8217;s + Edge of Night or Opportunity) deliver the highest FLUX percentage while also maximising armor penetration for kills. The lethality investment in FLUX is directly efficient \u2014 it&#8217;s a two-for-one where lethality both improves kill potential and improves the post-kill cooldown refund.<\/li>\n\n\n\n<li><strong>Track the R cooldown during multi-kill fights to know when FLUX refunds enable an additional R use within the same fight: <\/strong>In extended teamfights with 3\u20135 kill opportunities, track the running R cooldown and each FLUX refund mentally. After the first FLUX trigger, calculate whether a second R use might be available if additional kills come within the fight window. This is particularly relevant for Talon (AoE blade burst R) and Qiyana (AoE R can hit multiple champions) \u2014 whose R can generate multiple FLUX triggers from one cast if the blades\/shockwave hit multiple kill-eligible champions simultaneously.<\/li>\n\n\n\n<li><strong>In Arena with APOTHEGM, prioritise maximising the R&#8217;s single-use damage rather than building for R frequency: <\/strong>APOTHEGM changes the optimization target \u2014 instead of accelerating how often the R is available, maximise how much damage the R deals when it fires. Pair Axiom Arc with items that scale the R&#8217;s base damage: lethality for physical R abilities, armor pen for tank targets, AD for scaling. The 20% flat multiplier applies to the full R damage regardless of what components build it \u2014 every point of AD\/lethality\/pen scales the amount APOTHEGM amplifies by 20%.<\/li>\n\n\n\n<li><strong>Pair with The Collector for the 5% HP execute to guarantee kills within the 3-second FLUX window: <\/strong>The most common FLUX failure scenario is a target surviving at very low HP (sub-5%) and the kill window expiring before the holder can finish them. The Collector&#8217;s DEATH passive \u2014 executing targets below 5% HP \u2014 directly closes this gap by converting near-kills into guaranteed kills within the engage window. The Collector + Axiom Arc is a strong combination: DEATH ensures FLUX fires on targets who would otherwise survive the combo, and the 20 lethality from The Collector itself amplifies FLUX&#8217;s percentage refund.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>\ud83c\udfac Final Summary<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Axiom Arc is <strong>the definitive R cooldown management item for kill-heavy lethality assassins<\/strong> \u2014 a 2,750 gold legendary that converts the assassin&#8217;s core win condition (kills) into a direct mechanical advantage (faster R availability). FLUX&#8217;s <strong>15% + (0.15% per lethality) total cooldown refund per kill<\/strong> creates a compounding loop: full lethality builds maximise both the kill potential (more lethality = more armor penetration = faster kills) and the FLUX refund per kill (more lethality = higher FLUX percentage). The two scale together \u2014 the same items that enable kills also amplify the post-kill R cooldown reduction.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>0.5-second cooldown floor<\/strong> and the <strong>3-second kill window requirement<\/strong> define the boundaries of FLUX&#8217;s power. FLUX cannot provide instant R resets, and kills must be secured by the holder personally within 3 seconds of their own damage. These constraints make Axiom Arc a <strong>solo carry performance item<\/strong> \u2014 it rewards the player who opens kill combos and closes them personally, not the player who sets up kills for teammates. In coordinated team compositions where kills are shared, FLUX triggers less frequently and the item&#8217;s value per game decreases accordingly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>Arena transformation to APOTHEGM (+20% R damage)<\/strong> is a fundamentally different use case that turns Axiom Arc into a burst damage amplifier. Two entirely different champions may prefer Axiom Arc in Arena versus SR \u2014 the Arena version&#8217;s +20% R damage benefits champions whose R is their primary burst tool (Samira, Zed, Yone), while SR FLUX benefits champions whose R has a long cooldown and who fight in kill-frequent environments (Nocturne, Zed, Talon).

Example: Zed&#8217;s R at 40 AH has a 85.7-second effective CD. FLUX at 17.7% returns 85.7 \u00d7 0.177 = 15.2 seconds. The cooldown cannot be reduced below 0.5 seconds \u2014 FLUX cannot provide a full instant R reset.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q: Does FLUX work if an ally secures the kill I set up?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A: No \u2014 FLUX requires the Axiom Arc holder to personally secure the takedown within 3 seconds of dealing damage to the target. If an ally takes the kill, FLUX does not trigger for the Axiom Arc holder regardless of how much damage the holder contributed. FLUX is a solo carry performance mechanic \u2014 it rewards the player who both deals damage to and closes the kill on the same target. In team compositions where kills are shared or assists are common, FLUX triggers less frequently than in solo split-push or 1v1 kill scenarios.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q: What is the 0.5-second cooldown floor?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A: If FLUX&#8217;s refund would reduce the R&#8217;s remaining cooldown to 0 (fully resetting it), the cooldown is instead set to 0.5 seconds \u2014 preventing an instant re-use. This floor applies even if the remaining cooldown is already below 0.5 seconds when FLUX fires. In practice, FLUX can make the R available almost instantly after a kill (0.5 seconds after FLUX fires), but never provides a true instant reset within the same combo. The 0.5-second floor prevents kill-chain scenarios from cycling R continuously without any delay.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q: Why is FLUX removed in Arena?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A: Arena has different balance considerations than SR \u2014 Riot removed FLUX in Arena because cooldown refund on kills in Arena&#8217;s 2v2 short-round format would be significantly more impactful than in SR&#8217;s longer games. Instead, APOTHEGM (+20% ultimate damage) was added to maintain Axiom Arc&#8217;s identity as an ultimate-empowering item in Arena without the cooldown cycling risk. The AD is also reduced to 45 (from 55) in Arena alongside the passive swap \u2014 a net balance trade that makes Arena Axiom Arc a burst amplifier rather than a cooldown-compression tool.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q: Is Axiom Arc good on Samira?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A: Situationally \u2014 Samira&#8217;s R Inferno Trigger has an extremely short base cooldown (~8 seconds), so FLUX&#8217;s percentage refund returns only 1\u20132 seconds per kill in SR\/ARAM. The absolute second refund is small, but in rapid multi-kill sequences where 2\u20133 seconds can mean the difference between having R available for the next target, FLUX&#8217;s contribution adds up. In Arena, APOTHEGM&#8217;s +20% R damage is directly impactful on Samira R&#8217;s full spin duration \u2014 making Axiom Arc notably stronger on Samira in Arena than in SR. The AH from Axiom Arc also tightens Samira&#8217;s style-stack generation abilities, indirectly accelerating R availability through faster ability cycling.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Q: Does building more lethality always improve FLUX?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A: Yes \u2014 FLUX scales linearly with lethality at +0.15% per point. Every lethality item in the build simultaneously increases kill potential (more armor penetration through lethality) and increases the FLUX cooldown refund per kill. There is no diminishing return on lethality&#8217;s FLUX contribution \u2014 the 60th lethality point adds 0.15% FLUX exactly the same as the first point. Full lethality assassin builds (60+ lethality) maximise both axes simultaneously, making lethality stacking the correct optimization path for Axiom Arc holders.<\/p>\n","protected":false},"featured_media":14524,"comment_status":"open","ping_status":"closed","template":"","class_list":["post-15785","wiki","type-wiki","status-publish","has-post-thumbnail","hentry","wiki-category-items-lol-en"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.6 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Axiom Arc - MagicStark<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/magicstark.cz\/en\/wiki\/axiom-arc\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Axiom Arc - MagicStark\" \/>\n<meta property=\"og:description\" content=\"What is Axiom Arc?
