1 bar thats pretty quick, i tried fighting behemoth and the wolf thing and that took like 10 battles just to raise it up 4 points i mean the battles were pretty short cause it was pre emptive but still 10 battles is alot. so i will try your strategy
stack someone like Fang with all the TP-regaining equipment, and she gets the "gesalt/TPboost" ability, and just let her kill them all by herself. Just start the battle with her as Com, and the rest as Syn or Sab or something. I use Sazh, so usually its just Syn/Com(Fang)/Sab for me.
I give Fang a lv1 Punisher (for Stagger: TP charge) as well, since she gets instant chain from the gesalt ability too. I might just use one ignot and upgrade it to lv2 for TP Charge II and see how that goes.
so combined that with the TP stagger charge. (also pre-emptive strikes for easy stagger) TP can come rather quickly
