Nice! I've had a somewhat similar idea, a mage who either wants to cast Transformation to get access to his full powers (base form has -1 to all paths), or a mage who has magic power 1 and gets a random (which is automatically promoted to 2), or something along those lines.

Ninave: I presume it's done this way:
Lugh's intrinsic magic skills are one lower than the ones presented, but he has a special ability which gives him +1 in all paths. Just don't cast Transformation, get affected by Twiceborn, recalled via Ritual of Rebirth or something along those lines
