From describing it it sounds harder than the version I'm using (1.5 from the latest installer) so I can't be much help, but I tried getting earth+elemental and added effect stop in my physical attacker's weapon.
@Sega There's a few weird, possibly buggy, things I noticed.

I noticed this inaccessible NPC here when I went back into Kalm in Disc 3.

Both Cait Sith #1 and Safer Mog are susceptible to mini, which while being hilarious also looks really weird when one of them gets tiny in the middle of the fight.

In the July patch notes you said you could get Transfusion from manipulating Death Dealer, but it can't be manipped.
