How do I get 6 ATB slots?

Question

In FFXIII-2, I unlocked the Ultima Arrow and Meteor Javelin skills. Apparently, I need to have all the 6 ATB slots to be able to use them. But no matter how many crystarium levels I get, I no longer get the "+1 ATB slot" option when I receive a crystarium bonus.

So, how do I get all the ATB slots?

Answer 1

Ultima Arrow and Meteor Javelin don't require six ATB segments: they are what's known as full ATB skills, and require the entire ATB gauge, whatever the gauge's length is. For example, you can see Noel use Meteor Javelin with only 5 ATB segments in this video:

But, to answer your question, Serah and Noel both have weapons you can create post-game—Sagittarius and Mac an Luin, respectively—that will increase the ATB gauge by one. To craft them, you need:

• 2 × Trapezohedron
• 1 × Phoenix Blood
• 1 × Izanami (for Sagittarius) or 1 × Vajradanda (for Mac an Luin)

The trapezohedrons drop from the Long Gui in Archlyte Steppes -??? AF- when it's sunny, phoenix blood comes from Pantopoda in the later gates (like Academia -500 AF-, this video shows what they look like), and the base weapons are sold by Chocolina in Academia -500 AF-.

Once you have the required materials, Chocolina will craft them for you in Archlyte Steppes -??? AF-.
