The spell effect is actually part of a Particles Sampler I got from DAZ years ago, but you can tweak it a bit more.

The fingers was basically just an oversight on my part.

And the dress is the Morphing Fantasy Dress from DAZ. So I was using the morphs already included, but I thing I might give it a try in the Cloth room and see what happens.

I'll give the text another looksee too.
