Before you read this guide,Im warning you for my wrong grammar and spelling so sorry,and im just a new player in LoL so I dont really know very much about LoL champs but I post this guild because I felt that its a good build and pls Correct me if im wrong. This build works good for me so I hope that yours too. THX! ^^

You need to buy Daggers first so her attk. speed is faster then until you get Sword of divine juststay in your tower if you can push, you push then when you already bpught it tele. to your tower and get a kill. Then you build Trinity Force you need to buy Zeal first for the 8% movement speed so you can chase. then buy sheen next for mana and Phage to your attk. Then you buy Boots of swiftness to run faster and to chase then you get Zeal again for Movement and Attk. Speed then when the time you bought your first Pahntom dancer just find someone who is dying then kill then go back to your lane. And you need Warmog's for your HP cause Vayne is so squishible then your last item may vary. But for me I get Phantom dancer for Attk. and Movement speed.

For my rune's selection I just get movement and Attk. speed so you can kill fast. I dont know about the runes i put because I'm still level 14.

For my summoner Spells I get Heal and Teleport because Vayne is so squishible so you use Heal when your about to die. And Teleport for going back fast to your lane like when your buying something.

I'm sorry but that's all I know and thank you for reading my guide.
