Master Yi Build
Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
A work in progress, but publishing early for the sake of giving somebody the item build.
A quick note on the boots, the Mercury's Treads and Ninja Tabi should not BOTH be bought, but rather one or the other be chosen depending on the enemy team composition. Lots of physical DPS? Get some defense and dodge with the Ninja Tabi. Lots of CC and magic? Get some magic resist and lower the length of stuns, slows, silences, etc. with Mercury's Treads.
