Just thought I'd mention I've completed turn 5 twice in a row now without any issues at 400 acc using +21acc from stuffed cabbage. We usually beat it with 1 - 2 min left before the enrage timer. I would prefer to have more accuracy if the allagan pants ever drop, but there's really no issue completing the hardest content in the game with time to spare with less acc.

Also, though it's not reliable at all and I LB3 at the snake part, I usually parse the highest DPS in the group (not counting the pet).

It would be better to be closer to the ACC cap, but it's easily do-able even at ~400 acc with stuffed cabbage (+21 acc) when you don't get the drops you need from coil.
