I say one single suit, or maybe two, but "hand-placed" at randomized locations. Ie. The gauntlets could be anywhere from a predetermined set of 4 places, etc. for the rest. So yes you could check up on the internet, but you'd have to go through the trouble of checking all the possible places, rather than going directly somewhere without actually looking for it or ending there inadvertently.

Something like this. I would say anywhere from 5-10 in the ENTIRE game. I want it to be rare, but I don't want to have to alt tab to uesp to find out where the next piece is. I kind of think of it like the Sword in Halo, but more extreme. It is possible to get, but you only get it a few places unlike a Plasma Rifle which 9/10 enemies have.

I would say anywhere between 2-5 sets, if I recall it was actually impossible to get a full set in Morrowind without killing Divyath? Missing pauldron only added in expansion?

Anyways. Yea. Rare. Couple different styles of helmets, tho.

Dude, Daedric Styled Glass Armor would be so cool! And why not have two types of awesome armor in each group? Because at some point, you just have to look good to feel good.

After reading the title I thought you wanted 1 piece suits like fallout.

1 might be too rare. I loved how rare it was in Morrowind, but being unable to get it without killing an important NPC isn't fun.
2-5 sets sounds about right.

oh daedric styled glass as in if it were green/looekd like glass but with the kind of daedric look? yes that would be sweet but daedric toned down a little and called light armor, no thanks
