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., Bel'Veth's slash count, Jinx's rocket count). Stacking AS items and traits on these units compounds: faster autos, faster casts, and bigger casts.

The shop action that discards the visible champion shop and draws a new set, costing 2 gold by default. Players reroll to find copies of specific champions, since combining three of the same champion upgrades them from 1-star to 2-star, and nine copies reach 3-star. The shop also refreshes for free once at the start of each round. Some augments and items grant additional free rerolls or shop refreshes.
