Savage elves... no foliage. Well then that at first thought makes me think of tiny nord... but that's not right, they are elves after all! So, just a few minutes ago it hit me... emerald! They cant use wood but they can use rocks and that sorts why not use green stone? Then to make it elfy and fit their home, I imagined a sword or small hand sicle(made from a jaw of some lore creature I don't know or a giant bug's arm? idk) with emeralds twirling through it shaped in vines and leaves. That of course then seems too similar maybe to glass... but since its more of a design/camouflage, it wouldn't be big clunky armor for these little guys. I also kept thinking of bone cause of the greenpact but then thats like bonemold thats already a idea taken by the dunmer hmmm...(get back to you on that) I also thought encase they made a whole blade of emerald or a decent sided plate of armor somewhere to give that a wood elf feel you could have fossilize animals( or leaves? is that legal?

Alright that's all for now. Sorry I know I could have summed it up shorter but... nahhh :]
I hope this help spark some ideas for you Waalx, and ofc as everyone else says, fantastic work on WAC!
