i had to change what i wrote because my first reply didn't answer your questions
if your going battle fo i recommend fomal first and foremost i always shoot for max ata atp mst and luck and go for defense after i max out those
things that are a must
mg+/kroes sweater
hylian/rr
get a good bringer rifle or hi hit slicer of fanatic like 50 + even my 50 hit sof is not enough for me
glide is good for supporting
summit moon and twinkle star for good bonuses magic bonuses and there inexpensive
if you can i recommend getting a excalibur tellsis combo for your force that way you have
v101 equivalent speed boost and i think increased light and dark resistance or light and fire idk
its a hard hunt but 45+ hit is a good payoff #trust <------all that and still 4 unit slots free must have!!!
viviene<excalibur
bringer rifle<slicer of fanatic
vol opt<3seals<hylian imo then a rr on the side
glide
summit moon is a must
girasol is nice but i think a vivi will do you more justice and hit dam near all the time
