That leads me to some interesting thinking , AkhĂ´rahil. Though the game mechanics do not reflect it, there is a penalty for using magic (as there should be): The loss of ones humanity. A min/max player would wonder, ' Where's the problem?'. But from a literary (or possibly, if one is lucky, role playing) angle, this leads to serious conflict, and interesting stories.
Have not seen this dealt with in any way Gloranthan other than the old Dragonewt magic (RQ 3). It became harder to resurrect into higher draconic forms the more dragon magic one used. Pity it did not get taken up in this update to the rules. Maybe next time.
Cheers
