This is a solo player build. If you have a team or teammates who can communicate with, use mosh pit instead of Stage Dive.
Powerslide in, Face Melt them back! Do not go under towers!
Wait for perfect timing.
If they are moving in a small group, wait for enemy making a mistake, THAN take that hero out from the others.

U should use Stage Dive after gone home for some mana and hp. I suggest not to dive in a whole enemy party. Its still handy if u just use it to get there fast and not damaging anyone.
