Ye thx, I fixed all , and about boots or blade at the begin I think it is individual prefer)what about def item, it haven't to be only frozen mallet, it can be thorn mail, guardian angel and something else, and u need always buy last item to counter ur enemies(I think.

I see some things here..

1) No Quintessences
2) You havent used your level 18 skill point
3) Boots with 3 pots are usually a better start as they provide you a nice amount of mobility in the start itself. Take 1-2 Doran items later.
4) Although this is just preference, I generally take a Phantom Dancer after either the Infinity Edge or the Bloodthirster and then take the item I missed out later. This gives me a decent amount of attack speed which complements Silver Bolts.

Hope I helped :)

It is the best ranked guide for vayne Caz of she will have all at the end of game: slow, health(mallet), fast movement(phantom) and unreal critical damage.
