Flickerblades

Bonus Attack Speed makes a unit attack more often per second, which means more auto-attack damage and faster mana generation toward the next ability cast. Some carries scale beyond that — their ability itself fires more hits when they have more Attack Speed (e.g., the number of swipes in Aphelios's onslaught). Stacking AS items and traits on these units compounds: faster autos, faster casts, and bigger casts.

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.

Scales with Attack Damage (AD). Champions and effects flagged as AD-scaling get bigger auto-attack and ability damage when the holder stacks AD from items like Deathblade, Infinity Edge, Giant Slayer, and Bloodthirster, or from trait bonuses.

Effect fires on each basic-attack hit — every auto procs items like Red Buff (burn/wound), Nashor's Tooth (mana on attack), and Kraken's Fury (stacking Attack Damage per attack, up to 15). On-hit carries scale with attack-speed buffs, so stacking AS multiplies their damage and utility per second.

The carrier ramps power within a single round — Titan's Resolve gains AD/AP per attack or hit taken, and the Rapidfire trait builds stacking Attack Speed on every attack, up to a cap. All in-combat stacks reset when the round ends, unlike takedown-stacking which carries across rounds.
