trying to get the puzzle too open for the Helmet piece of the Azidal Set but it doesn't seem too want too open (completed Unearthed quest) also level 76 so i didn't think it would be a level req. issue as well.

Is the set unique in design?

No, I think It's all similar to the ancient nordic armor from regular skyrim (the one aela the huntress wears)

yeah i presume so its part of the "Kolbjorn Barrow" and its actually called "The Relics of Ahzidal" (sorry for the spelling before still half asleep) and sofar i've recovered the
Ring, Boots, Armor, and Gauntlets. i see the helmet but cant get the cage door opened.

The helmet is behind the two turnable pillars, right? I believe the pillars should both be snakes. (it's the symbol that wasn't used to get through the door or get to the armor in the previous room.)

Just so you know you have everything:

Armor
Boots
Helmet
Gauntlets
Ring of Necromancy
Ring of Arcane
Dragon Priest Mask

I think its double snake then pull chain

^ what he said.

Where's the Gauntlets?
