1. Increase Arcane Force level by completing daily symbol missions. Having 360 AF makes you deal 1x damage with no reduction, and 540 AF makes you deal 1.5x damage.
2. Use Wind Flash - Return! to deal 20% more damage.
3. Use Dragon Dive - Return, Green MPE potion, and Decent Speed Infusion Node to gain att speed.
4. Noblesse guild buff, Guild Blessing, Wilderness buff, Blue MPE potion, Hero's Echo, Ursus buff, etc.
5. Try to use Dragon Slam and Elemental Barrage without fusing because it gives you two very powerful skills to break music box with instead of one.
