The ring event that came with Chaos

Plus it looks cool.

Yeah i forgot to state this bit it is my biggest reason. There are no high tier masks so 3 watk and some stats is good enough for me. upgrading face accessories is basically one of the last things anyone should try to do in an economic sense. and the mask is just amazing in a looks sense.

Actually, if it looks anything like the dual blade event masks from before it doesn't look that great. But I would agree that it looks way better than most mouth equips.

Yeah, its better than a branch for a nose and they look pretty good or at least funny with all my hairs and equips on the characters i play most. Face accessories of all kinds are pretty disappointing in terms of looks in this game.
