Intelligence? Forget it, after adding it one must desperately read books. What if after two years he cannot comprehend a single skill? Who could he complain to?
Willpower doesn't work either. He was still afraid of pain and didn't want to be too resolute when facing torture. He should faint when it's time to faint and die when it's time to die. Of course, in the game, the fact that willpower can reduce stamina consumption is still pretty great.
Choose willpower, and one bar of stamina could be used several more times to perform skills. Choose agility, no bonuses to abilities, but a big boost to movement. A player without any agility couldn't climb a bare utility pole, as much as a player without strength couldn't lift a car. The most balanced choice is physical strength, with faster stamina recovery, an increased number of times abilities could be used, and longer sprint distances.
