blitz, swordtech, and other battle animations

What exactly are the intro animations for? Is that for the intro sequence as any battle starts?

After you select the skill, (example: a blitz, or a sword tech) the intro animation is that very brief animation before the move. Like the magic casting intro is that blue sphere that goes around the character. The Blitz intro is the bright flash. For Relic it is that glimmer of spiky light when the spell is absorbed, etc.

Also for the spell animations:
You have aura blast shown on your screen shot. If I wanted Aura Blast to look the same way as pummel, for instance. Would I select Aura Blast as you have in screen shot and then adjust Idx 0 -3 to be the same numbers as pummel?

Yes, that's correct.

Also thanks very much. You are very helpful.

You're very welcome.
