Total Damage for Phantoms

Phantoms already have 30% total damage from Aria buff and a 100% damage from DK's cross surge. You can get an extra 60% damage from final cut too, but its really a training type skill at best. In the end, just packing too much, don't need full math to notice you have too much already especially when you are aiming for 200%+ boss damage. Best to just straight out slap some % atk in between.

Final Cut is a 1.6x multiplier, not total damage, and @ Carlos, I'd recube, 1 line of 9% ATT would likely be better than 21% damage.
