I don't know much about Fire Veritas, but I'm guessing it's some kind of gimmicky combo where you hope for a good rng roll to one shot things? That's really not my playstyle, so it sounds like I can safely skip Setzer, which means I can skip this entire banner and continue saving (a rare luxury during 2 week mog events).
I originally was going to go for Tidus as my next big chase unit, but I'm thinking maybe Dark Veritas might be better, to better synergize with DCecil.
Finished up a second copy of blade mastery recently, so now I'm starting to work on some magic TM's to throw on Fryevia. She may not be a great chainer, but she does excellent "solo" damage, and since most trials are like 5 support/tank/heals and 1 dps, she can fill that 1 dps slot perfectly.
