I'm saying you can easily spare 2 INT, (since as discussed VIGOR, and CONTROL , and Cunning aren't super useful). you get extra Endurance ATT from skills. (so can hit 9 endurance SUPER EASY). So basically the 3 INT you most likely start with at creation, add another 2 INT, and max steward Focus, and put 1-2 points in medicine, and engineer. 994a.
