Which skill should use for Phantom
For how to get those skills as Phantom, go to this link (thanks to Golden Bamboo)
1st job: Haste (thief) /Magic guard (magician) (Dual Blade's Self haste have custom buff x2 damage, but too bad cannot use)
2nd job: Rage (Hero)
3rd job: Lucky Dice (Buccaneer/Corsair)
4th job: Elemental Force (paladin) (This thing better than Final Cut, tested. I think it is the Void Elemental - Damage % changed to Attack %, GIve 40% more attack - in skill changes for Paladin)
Also, this is what i tested myself. If you have better skill combination please feel free to post it here, thank you.
