As I mentioned before, in early stages , you can scale your stats points according to gear requirement 1st. Putting points in dex and int wont go wasted even though you are going to warrior path. For those undecided extra points, you can save them up 1st and decide later. No point for me to provide you a cookie butter build to follow, where its more fun to build something which you prefer. During my 1st play, I had 40+ unspent stats points at bout lvl20. By the end of the game, I actually put more points in int compare to str, cause I had alot gears which come with str stats on them. So equipments is another deciding factor as well for stats investment.
