Hello I am silver and I understand how the words of silvers can not mean anything to you but if not WELCOME. Also this is my first guide and that's why it sucks T_T

Also fun fact if your team is full AD and you think there will be a lot of Thornmail action I will warn you that since Yasuo's Steel Tempest counts as a basic attack it will hurt to fight BADLY like don't even pick Yasuo badly.

Bloodthirster This is a necessity for soloing baron as is Ravenous Hydra.
Randuin's Omen This item is good if your vs heavy AD and Banshee's Veil for AP.
Mercurial Scimitar This item if for when your against a team with an Lissandra or just tons of cc.

Now first things first this is a baron cheese so Vision Ward DAT BARON since they'll probably steal it otherwise also if you could get you team to pressure another objective like dragon or Bot lane this will greatly reduce the chances of the enemy jungler taking a hug dump on your parade then once you have your items Phantom Dancer , Infinity Edge , {{the bloodthirster]] , Ravenous Hydra and the boots of your choice your good to go.

You have learnt all a humble scrub can teach you I wish you use it caution and acknowledge that this power is deadly use it responsibly , or like a knife it may end up stabing you in the back after you juggled it. Ill be going now ..... Adios.
