Best Augment Combos with Keystone Conjurer

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.
