and working on Empy weapon for that hoping it will get me into some runs.
This is a complete waste of your time and you should stop immediately. COR is never invited to contribute damage at all, you exist to do your rolls and then help with haste/erase/-na etc. until you run out of MP.
Even if you do have time to shoot, the empy gun is trash until the supposed REM update. Get a Surefire Arquebus and never look back.
