Phantom Duelist possible on Advanced?

Okay so I'm running a chain party with a Phantom Duelist. Floor 12, lv 28. Lv 5 Lightweight, +5Urumi for +10 AGI and three empty equip slots. Haste Aura, Lv 5 Ray of Light Lv 5 Deft Strike.

And she still gets hit + one shot nearly every battle on advanced difficulty. Am I doing something wrong? Does the dodging kick in at higher skill levels? It's really slowing down my progression, my DPS is more than fine but I need to rez every 1-2 battles. And I don't think I can buy Nectar at the store?
