So as I understand it, when performing Thaumaturgy at the speed of Evocation with Sponsored Magic, you can use an effect from Thaumaturgy then you use the Evocation casting rules using the Thaumaturgy effect's Complexity for the Power.
Assuming I'm understanding that right, I had a question about Thaumaturgy effects that require you to Take Out the opponent, such as Transformation spells.
So let's say a wizard has a form of Sponsored magic that let's them turn people into squishy animals at the speed of Evocation (this doesn't seem out of line for faerie magic, I'd say).
If it were done with a Thaumaturgy ritual, the Complexity would need to be high enough to overcome their defense skill and roll, fill up all their Consequences, and take them out in one shot. So it seems to me that Transformation is handled as an attack that you have to succeed at completely in one shot. This is supported by the fact that killing spells are technically transformation spells if I remember right.
So for transformation spells at Evocation speed it seems to make sense mechanically to do the Transformation as an attack, with the Taken Out result being described as transforming them. Any consequences along the way should reflect the process of transformation (whether the stress, pain, or injuries of resisting or even partial transformation).
Most importantly, what that would mean is that instead of using the huge Complexity of a hostile transformation spell (which isn't really feasible with Evocation), you'd create a weapon power and then attack each round. In other words, it's no different from blasting them with a fire blast over the course of the battle, except that if you take them out you have a frog instead of a charred corpse.
Is this how you would do it? Is this talked about in the book and I missed it?
Thanks,
