It was my understanding that Enchanters made these, is that true?
I joined enchanter this morning and I have no clue has to what form is needed to make them. I checked the forms you can buy from the enchanter and the lorekeepers and didnt see anything that mentioned "purified essense orbs"

I wish I could help but I don't know. I have a dragon and a paladin. The paladin I don't play much and he's an outfitter.

I seem to recall someone was asking on the general chat channel about it. I think someone said they bought the purify essence formula from the enchanter trainer.
However, as you say, you didn't find any there.

Yeah, Ill have to ask around more online tonight, at work right now :(
Thanks for the reply though.
