I'm curious as there isn't anything explicitly in the rules against doing this, but can an investigator choose two trait cards that both have the attributes for Strength, Dexterity, and Marksmanship? Or do the two trait cards have to be from different attribute groups. If it is allowed, how do you handle attribute tests from the other attributes?
It doesn't seem like someone could (or should) do this, but there's nothing against it.
