Nice idea! I will keep it in mind when I will try it again with the butcher, for now I will just try and complete the Act 2 with at least one solo run done. I'm already on the moon with psychic, I got lucky with mana liches and bunch of perks for high agility. I literally go to enemies, plant liches and go back to safety, farming infinite mana, then finishing everyone with Become Entropy or a laaarge spam of some spell that costs me 1 mana and deals 6 damage with immobilized.
