Players on these servers, what quests are you looking forward to most? Caller Groo, I'm looking at you... https://everquest.allakhazam.com/db/quest.html?quest=1570
The final BiC augment is not tradeable. I don't know about the lesser forms. I confirmed this tonight.
In short - basically anything that has an achievement attached to it is fully or partially NODROP even on Free Trade servers as a rule of thumb.
The title of this thread threw me back to middle school, where as a clueless pre-teen I saw a girl had written "Aerosmith Rules" on her folder, and I wanted to know what these Rules of Aerosmith were. Similarly, I came into this thread wondering what the Mischief/Thornblade Loot Rules were that the OP was talking about. All this time I thought I was cool and understood things, but no, I'm just older and still an idiot.
