IIRC, 475 is the magic number for us in coil. We sit with 341 ACC base at lvl 50. So you need 134 ACC from gear.

With this in mind, I recommend Full Warrior's gear (Helm, Chest, Gloves, Boots). Allagan belt, pants, and accessories, and a Hero's ring.

With this set up you site at 131 ACC, and with food you are above the threshold. The you're going to have to get the Allagan bracelets form Turn 4 though (not too bad IMO).

Without Myth boots, you're going top have to grab the Allagan helm (Turn 5...) and then you will *barely* make the 475 cap with HQ La Noscean Toast.
