Wait, now I'm confused again. Tom
specifically said:
Spells are basically unchanged.
Spontaneous magic is changed. This is what I outlined above: You describe what you want to do, and how much power you put into it, and then you'll see what happens. How close you come to your intended effect will depend on how well you estimated the required power.
So are you saying that to start with, there are
no spells, and they are
derived from performing the same spontaneous magic over and over?
Or are you saying that Tom misspoke, and we do, in fact, have to get a GM ruling on
every single spell we cast, regardless of whether it's being cast against someone?
