Hating the limited units fights. Appreciate the guides, only reason I can do some of these at all. Missing units or not having ex levels really kills these though.
I ended up using Kall instead of Rhus (because EX2), I only knocked him down to 26% my first run and think I low rolled with Vanharma a bit. Tried again but did a BS chain with Vanharma and Kall on Turn 1 that knocked off 5% of his HP which seemed to help because I was able to kill on turn 4. Had Ayaka VC on Ihana and Yshe along with guts on everyone just in case Turn 5 happened. Kall only did ~2.2B damage with Vanharma being the real carry doing ~15.3B. Thanks for the vid!
Note that the 5T mission is just for a stmr moogle. I'm going to have to mix together a team without Vanharma or Lehftia. It really sucks that the S4 story units have no synergy whatsoever - Tulien does earth axe, Yshe does ice spear, Rhus does water sword, Neilikka is lightning fist and has a 1x LB mod, Lehftia is fire support, Kall is ice hybrid, Ilmatalle buffs ice but has wrong killers. Like... every dps has to do their own elemental setup, and the supports force them to dual element.
I wish Gumi would stop releasing temporary content that assumes everyone has every unit at EX3, or at least put them in their own set of Nemesis trials the way JP does. I'm gonna have to see if I can use Kall, Taivas, and I guess Lasswell.
Since I don't have Yshe & Vanharma, I managed to clear it at turn 11 using Taivas&Yshe, Runda, Lehftia, Kall, Taivas. I only missed the "Clear within 5 turns" mission challenge though.
So i've been trying this for a week and can't kill the 4th stage. I don't have Vanharma, only ex1 Rhus, ex1 Taivas, ex1 Ihana, ex1 Yshe, am i just out of luck and its impossible?
