Weapon #10 is dropped from the Horror boxes (monster #13). Is one of two rare drops so good luck with that.
As far as skills, I sort of cruised through a majority of the game on Effat's explosive strike tbh. Takes a lot but if you're willing to grind near the restore points, bonus. Besides, if you wait till after you beat the game you'll have a much easier time with upgrading skills. The diffuse/duplicate I really only found useful to fill in the extra boxes on the skill history list.
