So at last, after 9 characters and probably 700-plus hours of play, I stuck with a smith long enough to kit her out in Daedric armor that she made herself.

After improving a single piece of that armor to Legendary, my listed armor rating is 600-something. Just a bit past the effective cap of 567.

So if I understand correctly, there is now nothing I can do to reduce physical damage further. So smithing up the other pieces of armor would be a waste of ebony ingots, correct?

Similarly, enchanting the gear with heavy armor skill buffs would be a waste of an enchantment as well, yes?

Thanks in advance.
