Oh ya, I see it now. That is a really nice looking spell!!! It will also be useful for boulders and such. Maybe the config can change the missile. So for example, all the user needs to do is select IsProjectileArcane=true to get the one you have already, but if they want a bomb or a fireball, there could be those options too, which would automatically set a different group of effects.
I showed Icemanbo my spell pack and he said I should submit it. It's not as cool as your but I am considering doing it because I will learn a lot from the feedback. I was also considering making all the spells "no target" spells, so they just go off in caster's facing angle. What do you think?
