Best Advice 
In all seriousness, though, I got couple of beginner guides/playalongs in my [HC] Build & Guide Collection that are suitable for first char without any prefarmed gear. Probably the best endgame build for HC that I’ve played so far was the Avenger Warder with focus on HP regen which also facetanked Callagadra without a single HP pot (I did use other ointments though) and clears SR90+ consistently.
