So I've found the vampire royal armor and I was wondering if anybody knew if there is a whole vampire royal armor set or if it's just a chest piece?

Just the chest piece. Other than that you use the vampire boots and vampire gloves if you want a complete set.

Ok thanks. Do you know if there is some kind of vampire head piece? I have a full set I'm just lacking a head piece.

No vampire hoods. i heard once that there are but i doubt thats true. personally i just thrown on shrouded hood. looks just as cool.

nope. Just the armor, royal armor and robe. So far iv found 1 robe but its not the best robe lol

I read in another forum post that there are vampier hoods. You get them from dead vampires.

Throw in a shrouded hood if you want it to look cool, that's what I'd do.

There are vampire hoods. I got one from a radiant quest where i had to inform the jarl of riften about a vampire in her court. She then had me take care of the situation and the vamp had it on him.

the hood was called vampire hood? or was it just like a novie or apprentice hood?

I got one from this same radiant quest but in Dawnstar. Yes it's called Vampire Hood.

These radiant quests are part of the Dawnguard faction I take it?

You may be able to get it from some of the Vampire radiant quests..lots of betrayal going on among my character's people.

Yes. From Isran. There are also Vampire Gauntlets, which are light armor.

Well, I ask because I've been doing vampire radiant quests for the last five or so hours. I have no idea why, but I find I actually enjoy these quests quite a bit. I could never get into them elsewhere in the game, but I'm having a lot of fun with them now. Unfortunately, I have yet to run into a single vampire that even carries this item and all three people that I have encountered to suggest such an item exists all appeared to be playing a Dawnguard character.
