If you watch the intro, you'll get to a scene were Frog and Crono use X-Strike on Flea, another where Crono and Marle use Ice Sword on Zombor, and a third where Frog uses Frog Squash on a bunch of enemies.
Attractive Battler allows you to edit the techs or items used in those scenes, allowing up to 3 per fight.
I found the relevant data for weapon sounds. I can stick it in.
