So after getting to level 5 vayne yesterday, and then getting level 6 and 2 tokens towards level 7, I'd thought I should make a little guide about this build. This build is extremely good. You can kill people with about half health (possibly more, I can never get too late into the game with her) with one shot.

The skill sequence may look weird at first, but it's the best fitting. You will get 50% bonus dmg with level 3 tumble which is nice. The W (silver bolts) can do a lot of damage. If you can get 3 consecutive attacks on someone, do it, especially with level 5. It will do a lot of damage to any squishy, and once you get to late game, anybody.

If you are new to Vayne, you may or may not find it hard to condemn. It takes a while to learn the range of it to where you can stun someone. You can even use your condemn to use it as a escape if needed. You can condemn on any wall or tower. I haven't tested this, but I believe you can use it on Trundle's pillar and Anivia's wall or anything like that.

For ADC, you always want heal and flash. Heal is best since you will be squishy and heal has personally saved me so many times.
