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.
This is a critical plus attack speed build for Master Yi.
After a couple of test, I reached a score of 25-0-1 and so on.
Good at killing tanks and ranged (with highlander to catch them and kill them).
Marks and Quintessences with Armor Penetration - More damage
Seals and Glyphs for Crit Damage - 2x Phantom Dancers will give you good Crit Chance, so a little more Crit Damage with Armor Penetration is always good.
