I am EvilDeath66X or the Summoner, "GLinda Harble." This is not really a guide per say, mostly just looking to get opinions on my build for Vayne. But if it helps someone else out then great. I have tried many other Vayne builds but I don't really like them much. So the other day I sat down for a while and completely revamped my build. I was using "The Night Hunter" by Simplifyx,(Great Guide by the way, influenced this build alot.) however it was not quite what I was looking for... Anyway, after revamping my Item Set this is what I came up with.

*Note* This is a low-lvl build I am only lvl 13 at the time of posting this...
Also Please be polite and don't insult me because it is not an "ideal" build. I know it is not exactly good, but it is what works for me.
Bottom line, don't bash...

The first thing you buy every game is a Longsword and a Sight Ward, which is enough to use all of your starting gold. When in lane, stay until you have ~400+ gold so you can buy the Vampiric Scepter. If at anytime you are forced to retreat to base before you have enough to buy your next item, buy a Crystalline Flask, it is very useful and you will not have to constantly buy it like you do with Health Potions. After getting Vampiric Scepter, your item order becomes more flexible. It all depends on who is primarily in your lane with you. If it is a tank character, start on the Last Whisper as soon as possible. If your opponent frequently hits and flees, attack speed is probably going to be helpful, in this case start with Zephyr. Don't start on Runaan's Hurricane, Bloodthirster or Spirit of the Spectral Wraith until you have all of the previous items. Otherwise you will spend too much time trying to get them, when you can expand on your abilities until later, then dump gold into upgrading things mid-to-late game.

I know this may be spreading things a bit thin, by trying to cover too much instead of focusing on one thing like Attack Speed/Life Steal builds, but again, this is what works for me. I am only looking for opinions and helpful tips, not hateful bashers...
