Hello,
Obsidian Weapon Set includes 3 Weapons:
-Obsidian Edge ★★★★★
-Obsidian Carbine ★★★★★
-Obsidian Crusher ★★★★★
I guess that I'm only selling these as Set.
Feel free to make offer(s) here/Ingame/Via Steam I don't really mind.

My IGN is General-Ragequit but I prefer Steam http://steamcommunity.com/profiles/76561198044004272/
PS. Please remember that Unbinding Fee is 4000 CE x 3...

Thank you! ~General Ragequit
