Converting Shadowrun Magic to GURPS

[Crakkerjakk]

Mages are already going to be super expensive. I would strongly advise against doing magic as powers unless you want 350 points to be a baseline runner or something.

I'll run through your original post in depth later today.

EDIT: I misunderstood what you were saying. I agree with Diomedes that adjustable spells would work for this. Or any of the general guidelines from improvisational magic for cost of effects in Thaumatology.
