What you're wearing now based on the WAR set that's showing is more than enough for a PLD in coil at least up to Turn 5 (I've yet to even try Turn 5). You also don't NEED to +1 your sword and shield, but it is a nice damage/hp boost for you.

Upgrading your accessories (mainly the ring) would benefit you most, others may disagree given the fact that apparently the HQ Rose accessories are apparently better if fully melded from a min/max perspective.
