What is worth getting with Photon Spheres?

[Dark Emerald EXE]

So I just now (yes I'm late lol) decided to skim around that shop...and unless I'm overlooking the MAG devices, I didn't really find anything that "Caught my eye" as the Gunscissor. (4* Gunslash) with ??? III is something that can be easily done along what looks like the 4* PP Sub Unit with ??? III can also be done as well too easy and would seem like a waste of sphere.

Again unless I'm overlooking something.

I play RaGunner if that means anything...

You also need photon spheres now to get the latent ability from some of the weapons. You may want to keep it for future as they add latent ability to weapons that still don't have them (which is a lot of star 10 weapons)

Some superior MAG abilities like HP/B and Status Recovery/B.

Photon Collect for a better chance to add a status aliment to weapons.
