Weapon skills and Accuracy, I think. Mind may or may not have an effect on Morale (I seem to recall Morale is partially derived from Mind, but I may be dead wrong on that), and Strength doesn't really do anything yet, but is slated to be properly implemented, so stuff has weight, and encumberance penalties would apply if you went over your limit. I'm not sure if the design of that bit has been finalised yet though
