Apex Inventor ARAM Mayhem Augment Guide

"Tinkerer": All item effect damage +50%, trigger frequency -30%. The ultimate choice for effect-based champions.

"Master Inventor: Core effect: All item and rune special effects deal 50% increased damage Trigger frequency: Item effect cooldowns reduced by 30% Base bonus: Gain 10% attack speed and 10% ability haste Stacking rules: Effect damage increase multiplicatively stacks with other damage bonuses Restriction: Cannot increase base item stats (attack damage, ability power, armor, etc.)

All item on-hit effects (Luden's, Ice Gauntlet, Trinity Force, Blade of the Ruined King), rune on-hit effects (Critical Strike Missile, Magic Missile, Grandma's Hot Sauce), summoned units triggering item effects, basic attacks and abilities triggering item effects

Crusty Inventor: Equipment base stat bonuses, base skill damage, true damage skills, healing and shield effects

Jayce: Multiplicative stacking: Extremely high returns when stacked with other damage bonuses. 30% CDR applies to base cooldown, not proc chance. Rune effects also receive 50% damage bonus. Bonus effects persist after death.

"Gadget Expert: On-hit champions (Vayne, Kai'Sa, Kog'Maw, Ezreal) Marksmen reliant on item effects Champions frequently triggering item effects Hybrid champions

Gadget Expert: Ability-based mage (Ziggs, Vel'Koz, Brand) Burst assassin Pure tank Champions who don't rely on item effects

Inventor: Prioritize special effect items: Blade of the Ruined King, Nashor's Tooth, Iceborn Gauntlet, Luden's Echo for significant damage gains. Stack Attack Speed and Ability Haste to increase special effect proc frequency. Choose special effect runes (Critical Strikes, Magic Missile). Focus on sustained teamfights, don't just burst and leave. Combine stats for dual attribute bonuses to further increase special effect damage.

Apex Inventor + Upgrade Sheen: Apex Inventor's 50% item CDR dramatically accelerates Spellblade procs, while the upgraded Sheen effect deals 4% max health damage and heals for 3.5% max health per trigger. This creates near-constant burst and sustain on ability casts, turning every spell into a powerful damage and recovery window. Apex Inventor + Vulnerability: Vulnerability allows item damage and DoT effects to critically strike. With Apex Inventor halving item cooldowns, active items like Hextech Gunblade or Prowler's Claw can trigger more frequently, each hit having potential to crit for 145%+ damage. The 25% crit chance from Vulnerability enables this scaling. Apex Inventor + Upgrade Immolate: Upgrade Immolate synergizes with Apex Inventor by reducing Sunfire Aegis and Hollow Radiance cooldowns, while the upgrade grants 12 health per tick per enemy champion. Faster item activation means more frequent Immolate ticks in ARAM's constant teamfights, stacking sustain with damage output. Apex Inventor + Upgrade Mikaels Blessing: Upgrade Mikaels Blessing reduces the item's cooldown to 45 seconds, and Apex Inventor further accelerates this. The upgraded active cleanses CC from nearby allies, provides healing, and grants 65% tenacity for 3 seconds. This enables frequent clutch saves in ARAM's crowded teamfight environment.

Avoid Apex Inventor + Recursion: Avoid this pairing because Recursion grants 60 ability haste which affects champion ability cooldowns, while Apex Inventor provides 100 item haste specifically for item cooldowns. These are separate stat systems that do not stack or interact, making the ability haste from Recursion completely redundant if you are primarily seeking item cooldown reduction. Avoid Apex Inventor + Bread And Butter: Avoid this pairing because Bread And Butter grants 100 ability haste to your Q ability only, while Apex Inventor provides 100 item haste for items. These are different haste systems with no overlap. If your goal is maximizing item active usage, the single-ability haste offers minimal synergy. Avoid Apex Inventor + Bread And Jam: Avoid this pairing because Bread And Jam grants 100 ability haste to your W ability only, which is a different system from the item haste that Apex Inventor provides. Champions who want item haste for active items gain almost no benefit from single-ability cooldown reduction on their W. Avoid Apex Inventor + Bread And Cheese: Avoid this pairing because Bread And Cheese grants 100 ability haste to your E ability only, while Apex Inventor provides item haste. These stats apply to completely separate systems. Players seeking item cooldown reduction should prioritize augments that complement active item usage rather than single-ability haste.

Inventor: Don't pick for ability-only AP mages: don't benefit from item effects, low value Don't ignore rune effect bonuses: many focus only on items, forget rune effects Don't build too much basic stat items: Inventor boosts effects, not base stats Don't burst all at once: effect-based builds focus on sustained damage in teamfights Note item effect cooldowns: with increased frequency, use skills and autos effectively
