Hyper Skill build for Aran

All final blow, everything else is quite useless. You could use the Combo tempest hit increase and combo required reduce.

Bolded is especially important.

Keep in mind, to use any finishers during Unlimited Combo, you have to have that amount of combo first. Taking the reduced combo cost of Combo Tempest lets you use Combo Recharge and Unlimited Combo, and then immediately start spamming Combo Tempest.

Edit; Or you could take the point of extra combo generated by Combo Recharge. Both will let you spam Combo Tempest immediately during Unlimited Combo, however if you take the reduced cost of tempest, you will never have to use Combo Judgment again.
