Keystone Conjurer ARAM Mayhem Augment Guide

Mage Keystone: Significantly improves base stats and spell damage for mages, a universal core Rune for all mage champions.

"Arcane Maven: Core effect: Gain 30 base AP and 10% skill damage enhancement \nLevel scaling: Gain 2 additional AP per level \nBonus: Gain 5% AP for 3 seconds (max 3 stacks) after hitting an enemy with a skill \nStacking rules: Adds with other AP and damage enhancement effects \nReal-time effect: Attributes are immediately increased upon acquisition

Keystone Mage: Stacks gained when abilities hit enemy champions Gains bonus AP on level up Recalculated when AP changes

Keystone Mage: When basic attack hits, When ability hits minions, monsters, Healing and shield effects

Arcane Comet: Stacks can be refreshed by hitting enemies multiple times. Also applies to item spell damage (Luden's, Liandry's). AP converted from AD also benefits spell damage. Stacks don't reset on death

Keystone Mage: All mage champions (Jinx, Viktor, Ziggs) AP carry supports (Soraka, Karma, Nami) Hybrid champions (Ezreal, Jayce, Kassadin)

Keystone Mage: Pure AD champions (Draven, Darius, Zed)\nPure tank champions (Alistar, Leona, Ornn)\nPure auto-attack damage dealers (Vayne, Jinx, Draven)

Keystone Mage: Use early base AP advantage to pressure enemies Frequently hit enemies with skills to maintain stacks Combine with other AP items to maximize damage In team fights, stack to max before using ultimate

Keystone Conjurer + Magic Missile: Keystone Conjurer provides Arcane Comet and Summon Aery for consistent poke damage, while Magic Missile triggers on every ability hit to fire additional true damage projectiles. This combination transforms any champion into a poke powerhouse, as both keystones and Magic Missile activate simultaneously on ability damage, creating overwhelming sustained harassment that scales with distance traveled. Keystone Conjurer + Recursion: Keystone Conjurer grants two keystones that both benefit from frequent ability casts. Recursion provides 60 ability haste, dramatically reducing cooldowns to trigger Arcane Comet more often and maintain Summon Aery uptime. This synergy excels in ARAM's constant teamfights where spell spam maximizes both keystone effects for sustained damage output. Keystone Conjurer + Eureka: Eureka grants ability haste equal to 30% of AP, enabling mages to spam abilities frequently. This directly amplifies Keystone Conjurer's value by triggering Arcane Comet more often and keeping Summon Aery active on allies. The combination scales exceptionally well on AP champions who benefit from both the keystones and reduced cooldowns. Keystone Conjurer + Thread the Needle: Thread the Needle provides 18% armor and magic penetration, causing Arcane Comet and Summon Aery damage to hit significantly harder. Both keystones deal damage that benefits from penetration, making this a straightforward damage amplification combo. The flat penetration ensures poke damage remains relevant throughout extended ARAM teamfights.

Avoid Keystone Conjurer + Demon's Dance: Keystone Conjurer grants Arcane Comet and Summon Aery, while Demon's Dance provides Fleet Footwork and Grasp of the Undying. This pairing forces players to choose between two sets of keystones, wasting the value of one augment entirely. The conflicting playstyles—poke versus sustain—create inefficient scaling and redundant rune slots. Avoid Keystone Conjurer + Symphony of War: Symphony of War grants Conqueror and Lethal Tempo, which conflict with Keystone Conjurer's Arcane Comet and Summon Aery. Players cannot activate all four keystones simultaneously, resulting in significant wasted power. The stacking attack speed from Lethal Tempo also offers minimal benefit for poke-oriented Comet triggers. Avoid Keystone Conjurer + Impassable: Impassable provides Aftershock and Glacial Augment, adding yet more keystones that compete with Arcane Comet and Summon Aery. With a limit on active keystones, this pairing guarantees that at least two powerful rune effects remain unused. The defensive focus of Aftershock also clashes with the poke pattern Comet requires. Avoid Keystone Conjurer + Cerberus: Cerberus grants Hail of Blades and Press the Attack, creating another keystone conflict. Hail of Blades is designed for burst attack patterns, while Arcane Comet thrives on repeated ability poke. Press the Attack requires extended trades, which does not align with the hit-and-run style Summon Aery supports.

Arcane Comet: Don't think only pure mages benefit, hybrid champions gain high value. Don't ignore damage bonus from stacking stacks. Don't force pure damage build in losing games. Note enemy magic resist, build magic penetration.
