Shock/Health: Hardcoded animation?

Hi. I wish to change how Shock (or Health) works so it casts a different spell. I can easily make it so it casts anything else, but there's one problem: The animation. It stays like Shock (or Megahit) no matter what spell is chosen.

And no, the workaround of simply chainging Megahit's code won't work for me, since Madsiur gave me a patch to make the spell cast be different for an interval of levels.

Code:

Shock

C2/171A: A9 82        LDA #$82       ("Megahit" spell, which is what has Shock's data)
C2/171C: 80 02        BRA $1720      (go set that as spell/animation)

Changing 82 (which is the Megahit spell) to anything else will take on the properties of the new assigned spell, but the animation is still the same.

Help?
