Talk:Onyx (Element)/@comment-995908-20160610235618

Hmm...this is pretty similar to my idea for Onyx/Obsidian; a more brittle (still not completely offense-based) but offensive variant of Earth infused with Darkness.

I just call it Obsidian because that's honestly what I think it should've been called, tbh, since Obsidian is immensely sharp with average (5-6 on Mohs scale) hardness, so it fits the theme of an aggressive Earth variant, contrasted with Diamond, which is very defense-oriented.
