I was looking at the Ig spells & it occured to me. Magical flames can ignate mundane materials that the produce mundane flames.
Could this effect be translated into other forms?
Here are some toughts:
MuCo (Grow to size +2 for a year duration)
Have two mundanes produce a baby while under the effect of the ritual.
MuMe(Cr)(Boost the intellect, year)
Do this on your apprentice so he can learn spells.. or on yourself if you really need it.
I don't have more time... I'll get back to it later.
