Fun build for me was Caster/Battle FOmarl,
All the stuffs like V801 thingy for faster casting, ADEPT for some decent stats and TP cost reduction, Battle/units (V101, Centurion/Battle).
Support spell range boosting weapons! Tyrells Parasol for shifta/deband/?anti?/resta and Glide Divine for debuffing~
DPS weapons such as 100 Souls (Super strong weapon with spirit special!). Lindcray - (Rifle weapon for FO with spirit special!) and much, much more depending on what is fun to use for yous~
Bring a casting set as well! You don't need anything super great for this! You could always get that new Glide Divine V.00 for ultra strong single hit spells or use the normal P-wand + Hyrulian Shield combination to do some decently high RA damage.
I'm missing many things I think but overall you can be >>> Melee DPS >>> Magic DPS >>> Support and all once! Busy life!
