You just talking chapter 1?
ive done ch2 for 4 characters and ch1 for all of them..
Im also very confused because i cant settle for more than 3 characters jobs
olberic+apothecary
cyrus+healer
therion+merchant are all perfect.
first two curbstomp the living shit out of mobs no problem all by themselves. cyrus heals like a boss when necessary. (both magic stats are close to 600,mp is 340 iirc)
olberic has close to 4000 hp , can heal himself so i keep his defense low , poison enemies but mostly relies on last stand at low hp to wreck everything with the golden axe.
therion is the mp battery , mostly speed evasion gear , is borderline impossible to kill and shares mp and bp with rest.(both the others have decent mp regen too plus im working towards 1/2 sp cost for cyrus)
currently my 4th is tressa with dancer and just kinda spam that last random dance to up the challenge and hope for better rewards, sometimes i use her for breaks using mercenaries. this also means i have pretty much everything that i would need to break an enemy.
prim does absolute shit damage no matter what subclass i give her.
i wanna go with haanit for her beast capture which is infinitely more reliable that either of prims or the other girls summoning, but for the life of me i hate the hunter class itself. her bow skills are so boring .
