Hi there, i had the same problem, so what i did was, i played manually untill lvl 10 just to unlock some defensive skills both active and one passive then i started the bot and let it do normal nephalen rifts, normal difficulty, and i checked on it as it was progressing, like at lvl 20, 30 etc, to keep updating the skills, thats how i reached 70 on hardcore with demonbuddy, with a wizard btw, hope it helps u.
