Hey guys in this guide there is not really much i have to tell you about sion because its very simple, plus i know people out there hate reading long guides..... well mines not like that. **ONLY THING YOU MUST READ IS THE ITEMS IT EXPLAINS THE IMPORTANT STUFF ETC**.

with the runes the reason you got the crit damage runes is because at lvl 1, your crit deals 225% crit damage instead of 200% (which is normal) so its pretty good and once you get the infinity edge, u start to deal 265% crit damage when you crit.

same goes here not much to tell, just that its the usual ad Masteries, but you have the "Lethality", which adds onto your runes crit damage, and that givs it the extra 25% crit damage at lvl 1.

with the items your possibly wondering why there is no ad items till the infinity edge, reason being is sion is given enough damage already, that is why you stack his E first because he is given extra AD with his E, plus there is also your runes, so at lvl 1 you already have 94 AD!. this is also the reason why its perfect to do Crit sion, because he is given the extra AD so you can focus on getting crit items which well just make you OP. By the time you get ur second PD (Phantom Dancer) you will have 97% crit chance!! which brings me onto my next topic which is about the "avarice blade" i prefer to get that but its completely fine to get "Executioner's Calling" instead of the avarice blade. reason for me mentioning this, because when you get your second PD you will have 100% crit chance instead of 97% crit chance, it just takes a bit longer to get early game. ***LAST THING YOU MUST KNOW*** once you get your second PD it says to get "trinity force" BUT if you got the "Executioner's Calling" GET THE BLOODTHIRSTER FIRST reason being because you have 100% crit already, so theres no need to save up for the TF (trinity force) but after you got BT (bloodthirster) then you *SELL* the "Executioner's Calling" and get a TF. BUT if you followed the original build (getting the avarice blade) then sell the avarice blade for a BT.

with this i have already covered my reasoning of why you stack your E first in the items chapter... SO if you have still not read that plz do it now. but the reason i dont stack the W is because it doesnt really help unless your going AP, and the Q and E are more important.

reasoning for me having the "exhaust" instead of heal or ignite is because it acts as a stun at lvl 1, plus its really good to have to chase after people, and theres no need for ignite because your dealing so much damage by the time u get infinity edge. and flash is just needed i general.

and that is all i have about this build, with this i have gotten really good scores, e.g. i got 28/4/6 in one game and at one stage took out about 4 people while being 2v1'd.
another game i got 26/7/10 and another i got 22/2/3. SO..... ye its really good.

but thats bout it i hoped you like this build and if you do plz spread it, comment and vote.
