I wear Heavy armor, and as a Warrior, armor is my life.

I wear daedric armor from tip to toe, with the exception of Wraithguard and the Elm of Orcyn Bearclaw (class: 300)
My current Armor Class is 280

Do you know any way to improve?

Is your heavy armor skill at 100? Do you have a shield and is your block skill at 100? Your agility governs whether you get hit in the first place. Raise it to 100 and then enchant something with fortify agility for 30 secs (long enough for a fight). By not doing a constant effect (as I suggest in the other thread) you can get a bigger boost to your agility.

It sounds like you're at the point where you are powerful enough that most fights shouldn't give you trouble. Does your armor rating need to be higher? I think mine is around 110 and I don't have any trouble with Golden Saints or Daedra or anything. I do have the Restore Health constant effect items I mentioned in the enchanting thread though. They help a lot.

Yes, I am powerful enough to chop a Golden Saint in two hits, and no, my armor rating, block skill and agility are high enough that, provided they can hit me, I barely notice it.

I was asking about ways to improve armor class just out of curiosity, just to know if there are ways to do even better.
Thanks anyway.
