Upgrading Help?

Inner Potential? If you save all of the circulators you get / that go on sale from Jean that are lvl 7 or below you should be able to get 1-2 good inner potentials once you reach lvl 70 and unlock all 3.

He has crit IA, which is pretty much the best one a phantom can get.

[MENTION=2375]Mazz[/MENTION]; - have you tried replacing your empress gloves with Hero's gloves? (or are you already considering that) I know you're capable of getting them, and the 20%td/40%boss damage still beats the set bonus. Give that a shot and see if it helps, or just run the math if you have a "range calculations spreadsheet".

I would skip the ark rings unless primals are cheap on your alliance (like less than 800m or something). They're not a HUGE benefit and there's supposedly 3rd tier pottable rings incoming.

Dualing up on alchemy potions will help as well. Stack resistance pots + 70+luk potion, or if you're feeling really bold, 70luk potion and 24/30att potion. (your overall DPS will probably drop from the downtime though).

Finding a decent AB hat to swap on and off when rebuffing will be a good boost. IIRC it's 20 attack. May as well get decent CO if you see it cheap, it'll improve your carte dmg and Dark Harmony.
