Unstoppable Void

Oh I know, I was just doing the build order of what you should get. Battle Fury should eventually be sold, but it is essential for farm. When I get the cash I like to get boots of Travel too.

I tend to find that as Void, I get harassed alot and hence I always level up Backtrack, especially farming creep against enemy heros.

You can't build all that without selling Power Treads or Battle Fury. To fix, Assault Cuirass should be skipped in lieu of Heart of Tarrasque/ Butterfly.

For skills I prefer Chronosphere > Time Walk > Time Lock > Backtrack, with an early skill point in both passives. This build works too, however, as Faceless Void is weak early game regardless.

This isn't exactly a comprehensive resource, but I will yield that the ideas you have presented are correct for the most part.
