Representing the natural and innate capabilities of Companions, Followers and so on, traits measure raw capability on a continuum. We use two axes to capture our traits: one covering Physical, Mental and Emotional facets; the other covering Reaction, Finesse, Power, Capacity. All traits are measured in three positive and negative graduations from the average. Therefore:

If a trait is obtained twice, move it outward on the track, i.e. a Dwarrow Builder will be Strong not Sinewy

Please feel free to suggest other options as I'm struggling with some of these!
