A character's starting stat also determine their maximum potential stat.
This means if you start with a 1 in Strength, your maximum possible strength will be randomly between 10 and 12. You can "experiment" on a character to raise a stat, but this can only happen once per stat per character (and each attempt has a 10% chance to succeed and causes a -30 mood modifier with each attempt).
Each stat also has their own skill tree. Leveling up a stat gains 1 point to spend in the tree. All of a character's starting skill tree points are randomly spent.
