Thanks anyway. One question, can Dark Strike make up for a 200 ADB difference against a rapier with Fire Strike?
Maybe. It depends on the what the monster is weak to but many monsters don't have a resistance to dark damage but I can't tell how much 200 damage is for you. The best way is to actually test it for yourself and see how you do. Also, don't forget you can add an infusion outside of battle which lasts for 15 minutes per infusion.
