Found a perfect non-eth arioc's needle. Cant really think of any build that actually would use this, and being eth, it wouldn't really help on merc either. But since people tend to pay for useless stuff if it's perfect, i find myself asking:
What would (Jesus do.) YOU pay for it?
I think this is a viable weapon for a Spearazon build? Combined with the right gloves I think this would be a fun character to try...
I can't help you with the price I am afraid. But because it is perfect you should definitely expect a decent reward. You just need the right buyer If no one is interested you should make the build yourself.
