The footsteps at 1:41 (hard to hear because of the loud music) sound really heavy, and the armour is black with golden trim. That's why I think it is ebony.
look, here's a link to the concept art of elven armor, which looks exactly like the armor at 1:41

notice the feather-shaped armor on the legs, the hunch at the neck and the helmet look exactly the same in both images.
I'm hoping for lots of different plate/ringmail.
im not wholly into the conan barbarian outfits, except as a starting point. I'm also disappointed bc it looks like piecemental armor isn't in. i won't be that disappointed as long as there are plenty of full mail armors.
