Demonic Essence questionSource
#4 - 2013/01/15 09:20:00 PMAs we noted in our Patch 1.0.7 Preview, Elite monsters in Inferno will have a chance to drop an account-bound crafting reagent called Demonic Essence. We also intend for bosses in Inferno to have a chance to drop Demonic Essences, but that change may not be active until a later PTR build. Elites and bosses will have the same drop rates for Demonic Essences.
Thanks for the great question!

Those pesky Treasure Goblins weren't intended to be able to drop Demonic Essences, so we'll be checking their pockets behind the scenes to get this bug sorted out. :)
As noted in this follow-up post, we've decided to allow Treasure Goblins to retain their chance to drop a Demonic Essence.
