Random OS weapons

Sunqua is bad mod but has max dmg for the q4 sword, so l guess that you could buy buyer for that one, don't know about the price though

15 -10ar, 15vs hex etc are mostly sellable only if you find a collector, and price will be what they are willing to give. Check the buying threads, there are some people collecting swords and daggers out there (not sure if l am allowed to name them here)

Be cautious regarding that req4 Sunqua Blade. I could see that fetching a pretty penny depending on who's interested. The 15% vs Hexed mod is actually desirable to some and isn't a bad mod at all.

The rest seem like merchfood.
