I have an old school trick. Get your char naked, and dont forget to count in your prems int or str, and stuff like that. Then press c, then if you want to check if your full str, remove 19 to your int count. IF this number equals your level, then youre full str. Example, I have a char lv 19 full int. All naked, it has 38 str points. 38-19=19 which means im pure int since im lv 19.
We always understand better when we know why we are doing it. So I'll explain why this method can be valid. At start, you have 20 of each stat points. If you always give your stats in str or int at each level, you will still get one point in the other stat point because when you level up, one point goes to int, one to str, and then you have the choice for the next 3 ones. So at lvl 2, automatically, your char will have 21 int and str and etc. SInce we start at lv 1, that's why we remove 19 instead of 20.
Hope it helps
