Stats are point buy, 14 base. Sell a point to buy a point.
All base stats will equal 84, with a 12 point stat mod bonus.
Add Racial modifiers on after base stats are determined.
This may allow you character to have a stat that is greater then 20, or less then 8.
This last bit only applies to Mongrelfolk, Kobolds, Catfolk, and Goliaths as all other races only have a +/- 2 point variances.
