Magic
Magic represents both how much magic is in the user's blood stream, and how well he is able to focus and handle the magic stream through his Eye of Arkhan.
Increasing MAG to levels 4 and beyond, unless noted otherwise, takes away 1 from CON, AGI, and STR cap.
The above raw statistics are applied to a great many details in the world, and are the basic building blocks for how the character will interact with the world around him. Numbers called modifiers are increased, depending on how much you have in any given skill and are as follows.
1-4: +1 modifier
5-6: +2 modifier
7: +3 modifier
8-9: +4 modifier
10: +5 modifier
...11: +6 modifier
...12: +7 modifier
...13: +8 modifier
These are applied in many different situations, such as battle, and normal skill checks and are referenced where appropriate in the guide. Any statistic over 10 adds another one to the modifier.
