Ja.

That's an excellent point that I've never thought of nor was it covered by the rules really. In fact, rereading the rules and some notes I gave you bad information - I apologize - you'll need to use Area of Effect, not Speed/Range if you're adding more space to something. In GURPS, area is usually a circle radius and goes up 4 feet (it's in GURPS Powers somewhere). Speed/Range is usually added for shortcut types spells or when moving things over distance.

Ahhh, neat.

Thanks for clearing that up!

I looked up what you said about the radius, and it looks like I can find a source for that in Powers... but that only specifies the area for the Control advantage, and I can't seem to find anything about the generic uses of Area Effect in Basic Set or Powers.

I figure I'll just default to spherical area, though I suppose it is also important if the area was instead hemispherical or more of a cylinder with height equal to its width or something like that.

GURPS Magic should match that as well where it talks about Area spells. I don't think it's anywhere else in GURPS. I'll look when I walk up later today.
