One could use some sort of Soul Shard system, but this isn't always a option...Is there a better way of producing mob essence than having a cursed earth mob farm?
Basically I have my base set up like this. Cursed earth farm > mob essence > 2 Auto Spawner, witch and ghast > tears + glowstone go to reactant dynamo. My problem is getting enough glowstone/tears to expand my reactant dynamo, so I would need to increase my number of auto spawners whereby needing to increase my production of mob essence, however I am running out of room for the cursed earth farm, I already have it at a 24x18 room and its barely enough to power 16 reactant dynamos (I think its 16)
So chances are, you'll just have to increase the density of the cursed earth spawner room. I suggest making floors.
Mind you, if those 16(or so) reactant dynamos aren't cutting it for power(which is possible; they only output the same amount of power as every other TE3 Dynamo, they just have different fuels and are way more cool), maybe a different power source would be more useful. If you can afford those witch/ghast spawners, maybe add a creeper spawner(or simply a way to get gunpowder, TE3 works pretty well for this with it's gunpowder recipe being able to be automated and endlessly renewable if one is smart, but I'd suggest using Mek and whatever machine it adds that has a recipe to make gunpowder from 4 flint), send the glowstone(or redstone if you have a stockpile and source, such as those witches) into a MFR Auto Brewer(note: You'll need to add a MFR Harvester/Planter working with Netherwart if you haven't a mob related supply of some kind), make enhanced splash potions of regeneration/longer lasting splash potions of regeneration, and feed them into a Extra Utilites Potion Generation. Most potions in it are decently powerful, but each brewing "step" adds to both the power and the amount of time it lasts.
