Would you mind sharing a screenshot of her gear and or orbments? I've never been able to game the system like this.
Domination quartz + all str + 2 Passionate Rouge, something like that.
I ended up playing with delay, evade and speed casting though since it's more interesting. I made Rean into slow-hitter and linked him to Fie. She has 75% base evasion for now and is loaded with Impede gems. I am leveling up Katze quartz for her too since it's interesting.
I reached 5 firebolts/turn and maxed Criminal & Aries, but still didn't level up Pandora to level 5 for Emma no-delay Luminous Ray
I'm at chapter 6 and I think I'll try and finish game with 3 spellcasters. Here's my Elliot as he was during boss fight against Darth Vader:
I'll have to see if I will manage to get 3 casters to ~130 Speed since there's only 1 Skanda gem and I only have 1 Abyss Shadow because I never exchanged or grinded anything.
