What is Riftmaker? \ud83c\udf00<\/strong><\/h2>\n\n\n\n

Riftmaker is a legendary Mage item<\/strong> in League of Legends, categorized under Mage, Ability Power, Health & Regeneration, Ability Haste, and Life Steal & Vamp. It is the game’s primary combat-duration scaling AP item<\/strong> \u2014 designed for champions who fight prolonged engagements rather than single-burst windows. The longer Riftmaker’s holder stays in combat with enemy champions, the more damage they deal and the more sustain they recover through Omnivamp.<\/p>\n\n\n\n

The VOID INFUSION passive adds a second dimension: every point of bonus health converts to additional AP<\/strong> at 2%. This rewards stacking HP items alongside Riftmaker \u2014 a build pattern that simultaneously increases survivability and offensive output. At 350 HP from the item itself, VOID INFUSION contributes 7 AP, bringing effective AP to 77.<\/p>\n\n\n\n

At 3,100 Gold<\/strong>, Riftmaker is one of the pricier AP legendaries. The higher cost reflects the item’s triple stat contribution (AP + AH + HP), its combat-ramp passive, and the Omnivamp threshold reward. Sell price: 2,170 Gold<\/strong>.<\/p>\n\n\n\n

\ud83d\udcca VOID INFUSION \u2014 Effective AP Is Higher Than the Tooltip Shows<\/strong>The item tooltip shows +70 AP. VOID INFUSION adds 2% of bonus health as additional AP.From Riftmaker’s own 350 HP: 350 \u00d7 2% = 7 AP \u2014 not shown in the base stat tooltip.Total effective AP from the item alone = 77 AP.Every additional health item stacked on top further increases this: 100 bonus HP = +2 AP from VOID INFUSION.On HP-stacking AP fighters (Vladimir, Cho’Gath, Tahm Kench AP), the effective AP gap widens significantly.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

\ud83c\udf00 Passive Mechanics: VOID CORRUPTION & VOID INFUSION<\/strong><\/h2>\n\n\n\n

VOID CORRUPTION \u2014 Ramp-Up Damage + Omnivamp Threshold<\/strong><\/h3>\n\n\n\n

For each second in combat with champions, deal 2% increased damage<\/strong>, stacking up to 4 times for a maximum of +8%<\/strong>. At maximum stacks, you gain 10% Omnivamp (melee) or 5% Omnivamp (ranged)<\/strong>.<\/p>\n\n\n\n

Important duration notes: VOID CORRUPTION lasts 3 seconds when not fully stacked<\/strong> and 5 seconds when at maximum stacks<\/strong>. This means reaching 4 stacks (4 seconds of continuous combat) extends the active window \u2014 you retain the Omnivamp for 5 seconds after the last combat contact rather than 3.<\/p>\n\n\n\n

\u26a0\ufe0f Omnivamp Requires 4 Full Seconds in Combat<\/strong>Omnivamp does NOT activate until full stacks (4 seconds) are reached.In fights shorter than 4 seconds, Riftmaker provides only the ramping damage bonus \u2014 not the sustain.Champions who burst down targets quickly and disengage receive none of the Omnivamp value.The 3-second not-stacked window means if you leave combat before max stacks, the buff expires faster.The 5-second fully-stacked window rewards staying in sustained combat \u2014 the sustain window is longest when stacks are maintained.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

VOID INFUSION \u2014 HP-to-AP Conversion<\/strong><\/h3>\n\n\n\n

Gain ability power equal to 2% of bonus health<\/strong>. This passive is always active and scales with every bonus HP source in the build \u2014 not just Riftmaker’s own 350 HP.<\/p>\n\n\n\n

\ud83d\udca1 VOID INFUSION Rewards HP Stacking \u2014 Two Stats, One Investment<\/strong>Every HP item adds survivability AND passive AP through VOID INFUSION.On Vladimir (Crimson Pact passive also converts HP to AP): Riftmaker’s 350 HP generates VOID INFUSION AP, and Vladimir’s passive separately converts HP to AP. The two stacks independently.Cho’Gath’s R stack HP, Riftmaker VOID INFUSION, and Rabadon’s Deathcap multiplier compound: every feast stack increases both HP and the effective AP through VOID INFUSION.On tanky AP fighters (Galio AP, Tahm Kench AP), VOID INFUSION converts defensive bulk directly into offensive output.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Arena buffs both Omnivamp values significantly: <\/strong>melee Omnivamp increases from 10% to 15%<\/strong>, and ranged Omnivamp from 5% to 8%<\/strong>. At 4 stacks in Arena’s confined combat environment, Riftmaker’s sustain is substantially stronger than on SR. The AP reduction from 70 to 60 is partially offset by the enhanced Omnivamp output. Note the escAPA augment bug<\/strong>: VOID INFUSION AP is not converted via the escAPA augment in Arena \u2014 a known documented bug.<\/p>\n\n\n\n

\ud83c\udfaf Best Champions for Riftmaker<\/strong><\/h2>\n\n\n\n

Riftmaker is strongest on AP champions who engage in prolonged sustained combat<\/strong> rather than single-burst windows. The 4-second ramp to Omnivamp requires staying in combat, which means tanks, drain-tanks, and sustained-damage mages extract more value than burst assassins who enter, combo, and disengage.<\/p>\n\n\n\n
