Best Augment Combos with Witchful Thinking

Witchful Thinking + Eureka: Witchful Thinking grants scaling ability power throughout the game, which directly feeds into Eureka's conversion of 30% AP into ability haste. This creates a powerful scaling loop where more AP translates into more frequent ability casts, significantly increasing damage output and utility in extended ARAM teamfights. Witchful Thinking + Jeweled Gauntlet: Witchful Thinking provides a solid ability power foundation that increases Jeweled Gauntlet's critical strike chance formula, since it grants 25% plus 4.5% per 100 AP. The ability power also amplifies the damage of abilities that can now critically strike for 145% plus bonus critical damage, creating excellent burst potential. Witchful Thinking + Magic Missile: Witchful Thinking's ability power amplifies all ability damage, which triggers Magic Missile to fire three Firecrackers at enemies hit. The additional AP scales the triggering abilities while Magic Missile adds percentage max health true damage, creating strong hybrid damage output that is difficult for enemies to itemize against. Witchful Thinking + Phenomenal Evil: Witchful Thinking provides base ability power that helps abilities deal meaningful damage, which triggers Phenomenal Evil to generate permanent AP stacks on champion damage. This creates exponential scaling where the initial AP boost enables faster stack generation, leading to massive late-game ability power in extended ARAM fights. Witchful Thinking + Big Brain: Witchful Thinking grants scaling ability power that directly increases Big Brain's shield strength, since it absorbs damage equal to 300% AP. This combination provides significant defensive capability for mages, allowing them to survive burst damage and continue casting abilities in the narrow ARAM lane.
