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 build I use for myself when I use Yi and I find that it works realtively well.
The items picked for this make for a very fast and hard hitting Yi. By this I mean that Yi the items make Yi faster movement wise and in the respect of attack speed by hard hitting he has a high critical strike chance and high damage.
Runes mainly focuse on armor penetration and critical strike. This helps you put more damage out even on the heavily armored enemies.
The masteries foucus on attack in general and cooldown reduction.
I chose exhaust and flash for my summoner's spells. This helps Yi in the beginning of the game gather kills by slowing his enemies and being able to teleport closer to a target that is running away.
To summarize my build the point is to give you a lot of lifesteal, critical strike, attack speed, and attack damage. This build worked for me so I thought I would share so please do not be afraid to leave me feedback. Thanks
