Best advice for you is to hit 100 Dark resistance for PD hunting. Fairly easy to do via Dressplate armor this will make WOI alot easier for you. Next get yourself up to level 200, even at 150 you gain the ability to use Red Ring and it's costumes. For damage, an Arrest Needle with hit will work wonders or a Baranz Launcher, RAmar works extremely well with Demons special, it's pretty easy and cheap to obtain a Bringers Rifle with hit. As for more damage, make sure your Mag is properly stated for your class with an emphasis on Power. Use Power mats to boast your ATP further, eventually you will need to max your attributes on your favorite weapons.
