Deadlier Caps

Gold augment 

Gain a Rabadon's Deathcap. Rabadon's Deathcaps permanently gain ?% Ability Power whenever their holders score a takedown.

Deadlier Caps enables

  • Ability Power

    Scales with Ability Power (AP). Champions and effects flagged as AP-scaling get bigger damage, healing, or shield values when the holder stacks AP from items like Jeweled Gauntlet, Rabadon's Deathcap, and Nashor's Tooth, or from trait bonuses.

  • On Takedown

    Effect fires when a unit secures a kill or assist. In Set 17, Kai'Sa's passive "On takedown, gain 10 mana" is a clean example, and Seeker's Armguard stacks +20 Armor / MR / AP per takedown.

Deadlier Caps scales with

  • Takedown Stacking

    The carrier gains a permanent stack on each takedown (kill or assist) and keeps those stacks across rounds, unlike in-combat stacking which resets. Set 17 Ezreal is the headline example: every 8 takedowns earns him a permanent damage drone, so early-round farming compounds into late-game burst.
