Humans' strength and agility cap at 255. However, Legend's stat display doesn't go beyond 99, and the game's balancing requires you to go well above that number if you wish to be successful.
I don't think this is accurate. I managed to beat it without going "well above that number" without any problems. The last party I used was a human / mutant / monster / monster and I was able to beat "The Creator" without the chainsaw.
I consider the mechanical blindness of this game a feature rather than a defect. The player needs to identify what they can't understand or control, box it off, and use the tools that are known and available. I think it should be approach more like a board game (and there's quite a bit evidence to suggest that was the intent).
