Hey guys!!!!!!! this is my first Guide on mobafire, so i hope you will enjoy.
Why did i choose to start with master yi???????? Okay here it comes.
Master yi was the first i ever played in League of Legends. I played him like 200 games or more, So i wanted to share some tips, to all the new players, some there wanna try master yi and peoples there just want to be better to him.

Sry about my english.

Why did i choose this marks????????????
i choose greater mark of alacrity because, I start with the shoes, so they can't runaway, when i use alpha strike i can hit 2 times, before they begin to flee.

Greater mark of furor, I choose this because of the other marks, I get more crits then normal, so i also need more crit damage.

Why did i choose this seals?????????????????.
Greater seals of malice, I choosed this because of master yi need crits, Master yi also need crits from the start, hes start damage suck, but hes crit is op.

Why did i choose this Glyphs?????????????
Greater glyph of strength, I choosed this as i said in seals, hes damage sucks but not after this glyphs, This glyphs only helps in starts, When u played like 30 min and damage 500 each hit crits, it not help because, it only give 20 damage more or less

Why did i choose this Quintessence????????????
Greater quintessence of strength, it is the same reason as i said in the glyph.

Greater quintessence of malica, Is the same reason as i said in the seal.

Greater Quintessence of furor. It is the same reason as i said in the Greater mark of strength.

Offence first.
deadliness, because of the extra chance of crit in start.
Cripple, Because it exhaust the enemies in a longer duration.
archmage savvy, no reason just for getting the 4 for the next masteries.
Sorcery, Because of the cooldown to Alpha strike.
Alacrity, Because of the atk rate
Archaic knowledge. Not really any reasons just for the next 4 masteries.
Brute Force. I choosed it because yi need more damage in start.
Lethality, Because master yi need a big portion of crit chance.
Havoc, For both normal atk damage, and Alpha strike.

Utility.
Haste, Because longer time of duration to ghost.
Perseverence, Because master yi need more mana regen in the start.
Expanded mind, Because master yi need more mana in start for alpha strike,
Meditation, Because of the faster mana regen.

I choosed boots of speed as the first item, because He will run faster, so the enemies not flee because, master yi is weak in the start.
You choose about you want 2 health pots and 1 mana or 3 Health pots, but i always take 2 health and 1 mana, because he need more mana to get fb.

Berserker greaves, Is because of the ekstra atk speed.
Phantom dancer/seal, Is for the crit and for the extra atk speed and run speed.
Bloodthirster, is for the lifesteal and for the extra damage.
Infinity edge, Is for the extra crit damage and for the extra atk damage.

Why do i choose alpha strike first???+++++
I choose alpha strike because it damage, about 150 on enemy champs in start, and that is pretty much, but hes normal atk only damage 45 in start.

Why do i choose wuju style instead of meditate?
Wuju style give an extra damage when activated, but it also give extra damage each 7 hits.

Meditate. I not really use that alot, But it is good in the start if you enemies is feeded.

I choose Exhaust because, It do so the enemies run slower and do so they miss alot more, It can also own if your enemies run away, or maybe tower dive and you on really low hp.

Ghost, I only use it 2 fast get up to the enemies and pwn them. But it is also good before you get to lvl 6. Ghost is also good if ur enemies flee and on really low hp, it is also good to like tower dive and run away, but u have to use alpha strike, for the start of the tower dive.

Okay time to farm. When you are like lvl 8 or something like that, Begin to solo a lane or go jungling when the creeps just pop up. But first do that after you got vampiric scepter. And for like pwning all you need 1 thing, that thing is the red buff, you just use alpha strike on 1, and so 1 normal atk and so wait for your team to gank.
