That build is constructed for Master Yi that carry a massive amount of damage. He is also very fast that helps to control large area.

With all set He is just unstoppable. With good control or ambush he can slash 2-3 enemies in few seconds.

Master YI becomes very strong when you buy Infinity Edge. Only problem is that Infinity Edge is expensive and you need to collect gold for some time but then.... :)

In early game stage when Master YI is not so strong, it is good to develop Alpha Strike - it gives you some damage without involve in fight until you will have good opportunity. In middle and late game stage skill is used only to get close to enemy - damage of that skill is nothing comparing to Master YI male damage

Meditate - it is good skill but I’m using it only in late game stage against assassins ulti or when I`m defending.

Wuju Style and Highlander - grate skills that give you a lot of damage. Activate both when fighting with not running enemy. It is very importend to kill enemy when Highlander is activated. When you chase enemy, thing twice before active Highlander. Activate it always when you know that you will kill enemy, even if it is not needed - skills will restore after enemy death and you will have for short time better statistics.

Greater Mark of Desolation and Greater Quintessence of Desolation gives you good armor penetration what will increse your damage.

Greater Glyph of Shielding with Resistance (master) gives you some magic resistance - it’s nothing special but I thing there is nothing better in Glyph runes

Greater Seal of Evasion - hyy... I’m still thinking about that - not sure if doge is best option here. I also take Evasion(masters) and that gives me 8,75% of doge and I thing it is better then have about 30 of armor instead. In late games stage I sometimes sell Berserker Greaves and buy Ninja Tabli what gives Your Master YI nice deface.

Offence - 21 points. What can I say? You just mast have it.

Other 9 points:
I thing the best solution is to get some magic resistance and doge, you will have also 1 point for haste.

Best item for Master YI is Phantom Dancer. You just mast have it fast. Master YI has hi damage and increasing attack speed and critical strike gives you best damage per second. Phantom also increases your speed, what is very important for Master YI especially in Dominion.

In beginning best solution is to buy Berserker Groves to increase speed and attack speed. Then go for Phantom, starting from Dagger.

The best question is what to buy after Phantom. I’m going for Infinity Edge because it gives you best damage you can get. Also it is good to buy Vampiric Scepter - it is cheap and it gives you some defense (If you have no tough fights, buy it letter - after Infinity Edge). Start collecting Infinity Edge from Cloag of Agility - best solution for increasing damage in that point is increasing critical changes.

Sometimes I take Executioner Calling before Infinity Edge - I take it when I have very tough fights or team is loses - it fast increase my defense and damage for cheap price.

After I have Infinity Edge all is simple :) I finally have a lot of damage. Now, best way to increase damage is to increase your critical chance so first thing to buy is Cloak of Agility or Executioner Calling (if game is ending).

Now I have 2 ways:
1) If game is not ending I`m going for second Phantom that will make my damage extremely high. Then I`m going for Executioner Calling
2) If game is ending i usually buy Executioner Calling and then something cheap to increase damage (Cloak and Dagger is nice)

Sometimes to increase my defense I sell Berserker Groves and buy Ninja Tabi - but I do it on late games stages when I have a lot attack speed and tough fights.

Exhauste - You must have it. It helps you to fight against tough enemy and catch escaping enemy.

Ghost - some players use teleport instead. I thing Ghost is much better for Master YI. It is helpful in few things:
- catch escaping enemy
- run from enemy
- increase speed in first game seconds
- increase speed to be in significant places on time

With active Wuju and Highlander:
- Atacks in 1 second = 2.5
- Critical damage modificator = 2.6
- One hit damage (with master points) = 260
- Critical changes = 100%

Damage per second: 1763 !!!
(31 pionts of armor penetration)
+ 300 for Alpha Strike

PS. Timing of Master YI atack is essencial !
