bombard cores

[Espritduo]

You can buy the cores ahead of time, as well as the 1600 soldiery spring waters, and the 100k gil items. The quest requires turning them in, not buying them.

Unfortunately, you cannot buy the 1600 soldiery spring waters or the 100k gil items until you're on the quests requiring them. I would have loved to get those out of the way early like I did with the cores and crafted items, but they are unavailable to purchase until you actually need them.
