@HermitST to subvert this, experiment with your multi weapon ideas using low level weapons to start, if need be. It is far less expensive to combine these items. It is also possible to preview what the potential does for each item, so there doesn’t need to be a loss there at all.
And rest assured Topic Creator, you will have many weapons in your PSO career, and like the above poster said, the damage nerf is a non-issue once you learn how to parry. The straga series is technically the strongest for your weapon. You didn’t make the wrong choice
