Lux (Primal) enables

  • 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.

  • The unit-level resource that gates ability casts — champions cast once their mana bar fills, so low-mana units cast more often than high-mana ones. Spear of Shojin (mana per attack) and Adaptive Helm (amplifies Mana from all sources) push casts faster, alongside starting-mana augments.

Lux (Primal) benefits from

  • This effect triggers the instant a unit casts its ability. Items like Lich Bane and the Invoker Emblem reward you for landing as many casts as possible.
