Since Alpha 1, there have been several changes in the effect of the different attributes you can choose.
As it will most likely change again before going live, I only made a simple chart to give you an idea of how things affect your character at the moment.
How to read/translate this. Every attribute shows the changes with putting a certain amount of points into it (with the rest of the stats at 10).
Some attributes affect certain stat together.
*For example: Carry weight is affected by STR and CON.
If you have STR at 6 and CON at 6 the total weight you can carry is 62KG
Calculation: 70 KG (from STR at 6) minus the difference between CON 10 and 6 (8 KG) because the 70 from STR 6 is a combination of STR 6 and CON 10, which you have to correct.
If you have STR at 18 and CON at 18 the total weight you can carry is 146KG
Calculation: 130KG (from STR at 18) plus the difference between CON 18 and 10 (16 KG) because the 130 from STR 18 is a combination of STR 180 and CON 10, which you have to correct*
