Shields or Frames...

[Gynn Rei]

Skyly doesn't find good shields or frames... maybe create a Viridia and an Oran RAmarl and you should be able to get them in ultimate within lvl 50. A friend of mine managed to do it in 43 lvls. It took him 11 hours in total with a RAmar, though he duped and had lots of great RA weapons already.

Once in Ultimate you can telepipe yourself a Standstill Shield with Viridia and an Aura Field with Oran. You could also make a Greenill to get a Guard Wave because it has a lower lvl requirement though it has less dfp... lvl requirement of aura Field is 152 and that of a guard wave is 101.

Viridia will give you the shots you need along the way. Skyly has already given you some rifles I think? With the shots and Rifles you can either take a Greenill or an Oran more easily to the ultimate.

edit:

you can telepipe standstill from a mil lily in the VR Temple with Viridia and you can telepipe an Aura Field from a mil lily in the VR Temple with Oran and you can telepipe a Guard Wave from a pal rappy in the Forest with Greenill...
