In my opinion splitting your points into three different stats is too ineffective. The strength and endurance bonuses will be too little that they will become neglible. I suggest 25 spirit, and choose either maxing out endurance or strength from then on. Dividing your free points over three stats like that won't make a noticeable difference til much later, and by then it could still be regrettable. Personally I'd pick full spirit or spirit:strength, mainly because I enjoy dealing a lot of damage, and endurance doesn't do enough when in small increments, in my opinion of course.
Thanks Dynanub. :P I'll wait for some more opinions before I make my final decision.
