Master Yi enables

  • Attack Speed

    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.

  • Omnivamp

    Heals the source for a percentage of damage dealt (any type).
