No.Is there anything better than glowstone for a reactant dynamos liquid fuel?
Why don't you just make an animal breeder? Keep a massive stock of animals that are constantly breeding with wheat, and grind up the offsprings.Hmmm, I think I STILL need more curse earth. I am about 40% of the way down this natura tree. And I decided to go the grinder on every floor route. Still takes 5 minutes to fill up an open blocks tank with nothing taking any mob essence out. It also can't keep up with my 3 witch spawners.
Also, if you just want pure power, it would be far easier to make a sewage/sugar reactant dynamo setup. But, I assume you are going the witch route for fun.
