Hey OwnedCore,
Here's a little tip for you guys farming demonic essences and/or legendaries in general.
Go buy a puzzle ring, the goblin spawns quite frequently, I've been getting around 3-5~+ gob spawns in each of my runs, i've recieved legendary from the gob and he also drops a demonic essences. In the long run you'll profit from it, and who knows, maybe the big legendary will drop of it, or the last necklace you craft will be trifecta, thanks to extra essences drops! The price on the ring is like 4mil~ now so its not really that expensive.
