The GM may invent other forms. Set the per-slot cost to reflect the scope of available traits: 4 points for a short list, 5 points for a lengthy catalog, 6 points for nearly anything, and 7 points for anything. Cost per point in a slot should be 2 points if rearranging points is costly, slow, and subject to external interference; 3 points if just two of those; 4 points if only one of those; and 5 points if none of those.
