By selecting the more expensive choices first, you can buy the last Attribute for 2 points instead of 3 points.

Start with the following choices for your Sovereign:

Str 12

Int 12

Char 15

Dex 10

Wis 10

Con 11

Spellbook: Air

Current points: 17

Profession: Bard (probably doesn't matter)

Total remaining points = 17

If I select Organized for 10, Natural Leader for 5 that leaves 2 points.  I can raise Constitution to 12.

If I raise Constitution to 12 first before selecting Talents, it shows 14 points which isn't enough to buy Natural Leader & Organized.

So depending on the order I select, I can cheat and spend an "extra" point.
