So digging around a bit I came across this:

Porting the Traits and Passions from Pendragon to BRP

Seems to be a fairly light-weight means of bringing in Traits, and a little flavor, but I was thinking of reworking his rules accordingly for Magic World:

- Each character may have up to (POW/4, round down) player-chosen traits.
- If they are doing something in the manner of one of their traits, they can have a re-roll (max one per session per trait)
- Acting consistently in accordance with a trait gets you anadvancement roll on the primary skill used. (So if you have the Trait "Cultist of Bob", and you spend a session converting the masses to the dark ways of Bob, you would be looking at Oratory.)
- Acting consistently AT ODDS with an existing trait or in keeping with another Trait puts you on the path of aquiring that Trait at the cost of an existing trait.

Note that this advancement role is in addition to any which you may gain through normal play, so you can get TWO checkmarks... But this only buys you two attempts to advance the skill, not two advancements.

Thoughts?
