After weeks of just killing trash I got mine from the same place. I didn't realise it, but it was a body drop - not from a chest. Has that always been the case for adorn books? Oh well, now I just need to get some polished mana together!
There was a brief moment of cackling. Unfortunately, broker prices have started to come down drastically, so there's no profit to be made.
I'm with you. However I do keep checking the broker. It's down to 888 plat now on Funrest. I'm pretty sure I'll never loot one, I'm even surer I'll never harvest a spellshard.
I know they are body drops in heroic (and I'm assuming solo) instances. Unsure on overland drops though...I was just assuming it was going to come from a small chest, because all the other recipe books pop in small chests.
