What is Chempunk Chainsword? \u2694\ufe0f<\/strong><\/h2>\n\n\n\n

Chempunk Chainsword is the melee fighter’s and assassin’s Grievous Wounds item for sustained physical damage dealers<\/strong> \u2014 a legendary that inflicts Grievous Wounds on every physical damage hit, reducing healing effectiveness by 40% on any enemy champion the holder damages. The HACKSHORN passive<\/strong> covers all physical damage sources: auto-attacks, abilities dealing physical damage, and on-hit physical damage effects. Every hit refreshes the 3-second GW duration \u2014 a sustained fighter trading blows in melee range keeps Grievous Wounds active on the target indefinitely, effectively reducing their healing output throughout the entire fight.<\/p>\n\n\n\n

The shield-penetrating Grievous Wounds application<\/strong> is HACKSHORN’s most impactful interaction rule: the GW debuff is applied even when physical damage hits a shield and deals zero HP damage. This means targets using Sterak’s Gage shield, Maw of Malmortius lifeline, Immortal Shieldbow shield, or any champion ability shield (Lulu E, Janna E, Karma E) receive the Grievous Wounds debuff from the hit regardless of whether the damage penetrates to HP. Against shield-dependent healing targets (Aatrox with Sterak’s, Sylas with Immortal Shieldbow), Chempunk Chainsword begins reducing healing effectiveness from the first physical hit \u2014 including hits absorbed entirely by the shield.<\/p>\n\n\n\n

The stat profile (45 AD + 15 AH + 450 HP)<\/strong> covers offensive damage, ability cooldown reduction, and a substantial HP buffer in one item. At 3,100 gold, Chempunk Chainsword is among the more expensive physical Grievous Wounds items, but the combination of all three stats in one purchase makes it efficient for melee fighters and bruisers who need AD, AH, and HP simultaneously alongside the anti-heal function. The alternative physical GW item, Mortal Reminder<\/a>, prioritises raw AD and armor penetration over HP and AH \u2014 a different target profile for the same debuff.<\/p>\n\n\n\n

HACKSHORN \u2014 Grievous Wounds Healing Reduction MathStandard Grievous Wounds (SR): <\/strong>40% healing reduction. All heals, regeneration, and lifesteal on the afflicted champion are reduced by 40%.Healing at 40% GW (standard, SR):200 HP heal ability \u2192 <\/strong>200 \u00d7 (1 \u2212 0.40) = 120 HP effective heal.500 HP heal ability \u2192 <\/strong>500 \u00d7 (1 \u2212 0.40) = 300 HP effective heal.800 HP Soraka W heal \u2192 <\/strong>800 \u00d7 0.60 = 480 HP effective heal (vs 800 full).30% lifesteal on 500 AD auto \u2192 <\/strong>500 \u00d7 0.30 = 150 HP lifesteal \u00d7 (1 \u2212 0.40) = 90 HP effective lifesteal (vs 150 full).Arena NEW EFFECT \u2014 Escalating GW to 80%:Trigger: <\/strong>target heals for total amount over 60% of their max HP while continuously afflicted with GW (no GW gap allowed).Effect: <\/strong>GW strength increases from 40% to 80% healing reduction.200 HP heal at 80% GW: <\/strong>200 \u00d7 0.20 = 40 HP effective (vs 120 at standard GW, vs 200 without GW).800 HP Soraka W at 80% GW: <\/strong>800 \u00d7 0.20 = 160 HP effective (vs 480 at 40% GW).30% lifesteal on 500 AD auto at 80% GW: <\/strong>500 \u00d7 0.30 = 150 \u00d7 0.20 = 30 HP (vs 90 at 40% GW).HACKSHORN GW refresh: <\/strong>Every physical damage hit refreshes the 3-second Grievous Wounds duration. A melee champion auto-attacking every 1\u20132 seconds keeps GW active permanently on the target throughout the fight. A 2-second gap without physical damage to the target causes GW to expire \u2014 relevant for champions using ability-only rotations without auto-attack weaving.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Arena Chempunk Chainsword \u2014 Escalating Grievous Wounds to 80%:The Arena NEW EFFECT is the most powerful anti-heal escalation available to any AD item in the game: <\/strong>if the target heals for a cumulative total exceeding 60% of their maximum HP while continuously afflicted with Grievous Wounds from HACKSHORN, the GW strength doubles from 40% to 80%.Trigger condition breakdown: <\/strong>(1) The target must be continuously afflicted with GW \u2014 no gap in the 3-second window is allowed. Physical damage must refresh the GW debuff before each 3-second expiry. (2) The target must heal for a total of over 60% of their max HP during this continuous GW window. Against a 3,000 HP champion: the target must heal 1,800+ HP while Chempunk Chainsword GW is active to trigger the escalation.Practical example: <\/strong>3,000 HP champion with Soraka support and Immortal Shieldbow (lifesteal + lifeline shield). In Arena’s sustained 2v2 format, sustained heals over a fight can easily reach 1,800 cumulative HP on a durable target \u2014 triggering the Arena escalation. Once at 80% GW, 800 HP Soraka W heals for only 160 HP (vs 480 at 40% GW).Continuous application is mandatory: <\/strong>The escalation resets if GW falls off even briefly. Maintaining physical damage every 3 seconds (ideally every 1\u20132 seconds with auto-attack weaving) ensures the continuous application condition is satisfied throughout the fight.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

What Grievous Wounds Reduces \u2014 Full Coverage<\/strong><\/h3>\n\n\n\n

The standard 40% Grievous Wounds reduction applies to all incoming healing effects<\/strong> on the afflicted champion \u2014 no healing source is exempt from GW’s reduction. The coverage includes:<\/p>\n\n\n\n

Healing Type<\/strong><\/td>GW Interaction<\/strong><\/td><\/tr>
Champion ability heals<\/td>Soraka W, Senna passive, Aatrox W blood pool, Sylas W, Vladimir Q, Grasp of the Undying \u2014 all reduced by 40%<\/td><\/tr>
Lifesteal<\/td>All lifesteal from items (Ravenous Hydra, Immortal Shieldbow) and runes (Lethal Tempo on-hit portion) \u2014 physical damage lifesteal reduced by 40%<\/td><\/tr>
Omnivamp<\/td>All omnivamp (Riftmaker, Goredrinker, Ravenous Hunter) \u2014 healing from all damage types reduced by 40%<\/td><\/tr>
Health regeneration<\/td>Base HP regen and regen from items (Warmog’s HEART, Spirit Visage passive regen) \u2014 regeneration rate reduced by 40%<\/td><\/tr>
Spellvamp \/ AP healing<\/td>AP ability healing (Moonstone Renewer STARLIT GRACE, Redemption, Echoes of Helia) \u2014 reduced by 40%<\/td><\/tr>
Shield HP restoration<\/td>Shield HP that absorbs damage does NOT count as healing \u2014 shields are NOT reduced by Grievous Wounds<\/td><\/tr>
Revive effects<\/td>Zilean R, Guardian Angel revive \u2014 NOT healing, not reduced by GW<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
\u26a0\ufe0f Key Distinction \u2014 Shields vs Heals:Grievous Wounds does NOT reduce shield HP absorption. <\/strong>A Sterak’s Gage shield, Lulu E shield, Janna E shield, or Immortal Shieldbow lifeline shield all provide their full HP absorption value regardless of Grievous Wounds.However \u2014 HACKSHORN applies GW through shields. <\/strong>When physical damage hits a shielded target and is fully absorbed by the shield, the Grievous Wounds debuff still lands on the champion. So the sequence is: hit lands \u2192 damage absorbed by shield \u2192 GW applied to champion. The shield blocks the damage but not the debuff. After the shield is depleted, subsequent heals on that now-GW-afflicted champion are reduced by 40%.Practical implication: <\/strong>Against Aatrox with Sterak’s Gage \u2014 the first physical attack into Sterak’s shield triggers HACKSHORN GW, so when Aatrox’s Infernal Chains (E) and Blood Price (W) begin healing mid-fight, GW is already active from the shield-penetrating application and those heals are already reduced 40%.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Maintaining GW Uptime \u2014 Refresh Mechanics<\/strong><\/h3>\n\n\n\n

HACKSHORN’s 3-second GW duration refreshes on every physical damage hit. The practical GW uptime target is one physical damage hit every 3 seconds or faster<\/strong> \u2014 which for melee auto-attackers (standard 0.8\u20131.0 attack speed) means GW stays active every 1\u20131.25 seconds from auto-attacks alone. The 3-second window is only relevant for ability-only phases where auto-attack weaving is interrupted.<\/p>\n\n\n\n

Champions who fight in melee range with continuous auto-attack patterns \u2014 Darius, Mordekaiser, Garen, Irelia \u2014 maintain HACKSHORN GW at permanent uptime<\/strong> throughout every sustained melee fight. The 3-second expiry is never reached as long as the fight continues and auto-attacks are landing. This is the primary reason Chempunk Chainsword outperforms Mortal Reminder in sustained melee matchups: the auto-attack refresh guarantees continuous GW without relying on ability timing.<\/p>\n\n\n\n
