So if I wanted to just make the ultimate mage custom character what would you recommend I build?

Basically title, I find the magic system pretty neat, but find having to branch away to the other lifestyles can get in the way.

So if I mage a custom character what traits would you use to make it the top, under 400 points, magic build starting off.

Also are there any specific starts you use, Ruler or Adventurer, you prefer.
