Mixing kinds of Magic

[Michael Cule]

I was thinking about having different kinds of magic in the world and yet having some sort of common basis.

I was also thinking of using Ritual Path Magic in a GURPS Deryni game and yet allow the sort of quick cast magic that the Deryni are depicted as using as well as as the complex ritual stuff.

I had already decided in my own campaigns that Mage-O is a physical trait and can be inherited but Mage 1+ is a spiritual trait.

So how would it be if there were separate Magery advantages but only at the higher levels. That Magery 0 allows you to cast the base levels of any discipline but the higher levels are distinct advantages: Magery (RPM) Magery (Standard Magic), Magery (Threshold Magic).

Perhaps you only gain access to the higher types after training/initiation and then it's fixed.
