Never, ever force a Phantom Grid for the sake of having a Phantom Grid. Having a Phantom is nice, but it's the cherry on top of your cake, never prioritize the cherry over the cake.

And for water...? Yori Lance, 4 Ophiel Lances, 3 Ophiel Bows (better is obviously better), and two more out of Phantom Lance/Ophiel Lance/Ophiel Bow. Notice that you will be made out of paper, so this set-up is literally made exclusively for Yori bombing raids. It won't solo anything and it pretty much requires manualing.

If you've done stops 1-4 for Yori, you don't need to do them for Yori ever again. If you want more Lances, you can keep repeating step 5.
