Can i use this for leveling from the start and how? I am sure it cannot be fully AFK, i will probably have to equip him and build passive tree manualy. It doesn't pick up white items...
unfortunately, no not really. - Manually play the char and get him to ledge, equipping your char etc.. - Run ledge until you're level 12~14, clear the rest of act1 manually - Run Southern Forest again until you're level 20~24 clear the rest of act2 manually - Run City of Sarn (or Felshrine since Perpetus might give you trouble) until you're level ~32 - Manually clear to Docks, run Docks until you're in the 40s, manually clear act3 Rinse and repeat for Cruel and Merciless.. easiest way to get your char up there.
Vitality/Purity of elements + RegTotem + anything should work, my scion is doing fine on it. btw, CoS isnt really easy to farm, you should farm fellshrine/any act2 decent farm area before going for CoS
It's been a while and I've botted like 7 different builds through it, so it's not just 1 build. The only 2 I remember having an issue with were an LA ranger and my summoner.
Never had any problems farming City of Sarn, I'm even doing it at the moment with a level 57 char on Merciless( the zone is 61 ) with a common Double Strike / Spectral Throw build. People should really know how to play a game before botting on it. I suggest you to read PoE forums with builds, the general discussions, reddit, etc.
