Good guide! One tip I'll add is for the final boss. If you have a BLM, as soon as the boss lays down the seeds, have the tank attack the boss and hold it so it doesn't move. Then BLM locks onto the boss and spams Fire II. This will hit ALL of the seeds and take them out quickly. (I've only tried this with 1 handed staffs that have faster cast time then the 3+ second 2 handed ones.)
