You could post the codes of your spells, if it isn't too troubling.
I tested this spellpack a long time ago, so I'm not sure if it's still like this but here's my mini-review:
Seismic Bounce:
Nice effects, probably my favorite spell of this pack. However, the hero sometimes jumps to a really far-off place. (This probably has to do with being too close to the water.)
Suggestion: Make the jumping less random. (Ex: Have the spell be a targeting image spell and the jumping limited to that area.)
Stone Skin and Heavy Smash:
Kind of bad since both rely on
-
Unit - A unit Is attacked
Stone Skin was kind of meh as it was basically a modified Inner Fire. Heavy Smash seemed like a custom Bash to me, so the effects weren't too pleasing.
Suggestion: Allow Stone Skin's attack damage reduction to scale up with level. That would make it more interesting, but probably would need hashtables.
Ground Fury:
Opinion: The effects conflict with each other. (Knocking back a unit makes it harder for the rocks to hit them.)
The description and the name also conflict with each other. ("dancing" and "Fury")
Edit: Redownloaded the pack and most of my comments still seem valid.
Use Triggering unit instead of Casting unit.
Some other opinion: I found the commenting kind of annoying but were good for explaining what was happening.
