Just like the one you can find in BGEE if you do the new quests. It doesn't have to be magical, just non-random...
I note that a non-magical set of full plate has been introduced into the game (probably because previously they were all magical, which meant none could be combined with protective items?)
I think at the moment there are two magical sets of elven chainmail available and both are random, for the first time ever I failed to find either on a run through, which I felt made my bard look a bit silly.
Do you think a non random suit should be available somewhere? Or is it better we just take our chances with the random drops?
