I realized that managing a Hero may not be as obvious as I made it sound, so I made a series of examples to hopefully make it clear how the whole stat modification and special power points work. I'll post them here as well as in one of the reserved post slots.
HERO CREATION EXAMPLES
Basic Example:
Example 1: Changing Class, Choosing One New Special Power Each Level
Example 2: Choosing Multiple Special Powers
Example 3: Leveling Up Special Powers
Example 4: Human with Sub-Class
Example 5: Wizard with School of Magic Choice
Example 6: Changing to Wizard Class from another Class
And here is the most recent ERRATA found.
