Master Yi, The Wuju Bladesman is a melee champion. Before the 3.10 Patch he was commonly played in two different styles, either as a melee carry with a focus on building attack speed, or as an AP carry, as his Alpha Strike and Meditate scaled very well of AP. However since the rework it's not efficent to build AP on him anymore. His kit gives him a couple of powerful steroids and a channeled selfheal with additional defstats. With his ultimate on, he is immune to slows, and also gets cooldown resets upon his other abilities when achieving kills or assists. His limitations are his total lack of any form of crowd control and the fact, that he has to get into melee range for his autoattacks, while being relatively squishy. His selfheal can be interrupted by hard crowd contral such as stuns, knockups and knockbacks.
