If you're using AF+1 Helm, you should use the AF+1 boots as well, either that or use allagan in both slots (helm doesn't drop till turn 5). Honestly, I'm wearing myth helm, and hoplite chest (same acc as myth chest), and DL pants, and if I get the mytho boots I will have 465, with food that gives me enough accuracy to do turns 1-4, HOWEVER I only have DL accessories, no allagan, and the DL earrings don't even get accuracy.

So, there's still plenty accuracy to be gained from the allagan belt and accessories and with Bravura not giving any accuracy. You should be fine buy grabbing some allagan accessories, if you're close to turn 5 I'd say wait it out for the allagan helm if not, get the AF+1 boots. After the patch, 495 will barely be two weeks worth of grinding.
