Gorgon + soul vortex

[Quitschi]

Yes the gorgon was created by a wish to serve as a sc.

When i watched another battle the SV effect (these little white blobs around the caster) ocurred, but not every round, something seemed to interrupt it by time.

You might just be getting a graphical anomaly. I often (running Vista, BTW) have firebals appear as tiny little sparks, or the bottom halves shaved off of lightning bolts. Could be something on that order.
