Pathfinder: Dice Assignment

The Dice Assignment system of ability score generation is designed to create "realistic adventurers," who have strong abilities overall but also have natural variability. It attempts to balance the pure randomness of the traditional "4d6 assigned in order" system against the opitimization of a point buy system.

How To Use

 * 1) Create a pool of 26d6. (You don't actually need twenty-six dice, but you will be rolling a total of 26d6 over this process.)
 * 2) Assign any number of dice to each ability score. You will roll that many dice to determine that ability score. Important ability scores should be assigned more dice, while those with less value should be assigned fewer dice.
 * 3) *Each ability score must have at least 3d6 assigned to it. Apart from that, you can assign your dice without restriction.
 * 4) Roll your dice now. Keep only the three highest results from each roll.
 * 5) You may optionally swap one physical ability score (STR, DEX, CON) with another physical ability score, and one mental ability score (INT, WIS, CHA) with another mental ability score.
 * 6) Increase three different attributes by 1 point each.
 * 7) Mulligan: Optionally, if your highest ability score bonus is +2 or lower, or your net ability score bonus is +3 or lower, you may restart this entire process.
 * 8) Apply your racial ability score modifiers. You are done.

Example
Jon wants to make a dwarf fighter using the Dice Assignment system.
 * 1) Jon gets out a bunch of d6s.
 * 2) Jon has 26 dice to assign to his ability scores. He assigns them as follows:
 * 3) *STR : 7d6
 * 4) *DEX : 4d6
 * 5) *CON : 6d6
 * 6) *INT : 3d6
 * 7) *WIS : 5d6
 * 8) *CHA : 3d6
 * 9) Jon rolls his dice based on these assignments and gets the following results:
 * 10) *STR : 16 (6 5 5 4 3 2 1)
 * 11) *DEX : 14 (5 5 4 2)
 * 12) *CON : 14 (6 5 3 3 1 1)
 * 13) *INT : 11 (5 5 1)
 * 14) *WIS : 9 (4 3 2 2 1)
 * 15) *CHA : 9 (4 3 2)
 * 16) Jon decides to swap his Wisdom and Intelligence, resulting in WIS 11 and INT 9.
 * 17) Jon wants to boost his Strength, Constitution, and Wisdom. STR 17, CON 15, WIS 12.
 * 18) Jon's highest ability score bonus is +3, and his net ability score modifier is +6. He does not qualify for a mulligan.
 * 19) As a dwarf, Jon's character receives CON +2, WIS +2, CHA -2. This brings his final ability scores to:
 * 20) *STR : 17
 * 21) *DEX : 14
 * 22) *CON : 17
 * 23) *INT : 9
 * 24) *WIS : 14
 * 25) *CHA : 7
