I am having trouble getting Ahzidal's armor. I was able to open the floor grate and have cleared everything in the barrow. I have all of the other pieces to the armor along with Ahzidal's Mask. The armor is in the room with the lever and a pillar on each side of it behind a couple of thrones. I tried all combinations on the pillars using the same animal on each pillar, both birds, both fish, and both snakes. Across the room are two birds and on the side walls each has a moving door with a fish behind them. I don't use heavy armor, but I would like to complete the set. I left the barrow hoping it would reset and I could open the door keeping me from getting the armor. I hate these kind of bugs.

Been a while since I did it, and I do not remember where the armor was, the room you describe as two combinations, one to open the floor grate and one to open the small alcove. The two eagles open the floor grate I think, the two fish open the other door. Two snakes open the door down the bottom of the stairs. Get the fish alcoves open by pulling the chain again as you can see the fish, have both open, move the pillars to the fish symbols and then pull the lever and see if that works. If you already have them on the fish, maybe change the pillars to the birds before pulling the chains.
