What is the purpose of the dice roll at level up?

When a player levels up in campaign mode, there is a dice roll (2d6) before you are allowed to choose skills and/or pick an attribute to increase. What is the purpose of that dice roll? What happens if I roll double 1s or double 6s?

Solution 1:

Each skill is in one of five categories: Mutation, Strenght, General, Agility or Passing.
All of these categories are not available for every player type. And some may be accessable only if you roll any double (double 1s, double 2s, etc.) These go by player types, not team races, so these may vary within your players.
You'll see under each category either

• Normal (always accessable)
• Double (accesasble on doubles)
• No (never accessable)

Also, if the total of the roll is high enough, you can in stead choose to raise one of the players attributes as follows

• 10 or higher: Raise MA by 1
• 11 or higher: Raise AG by 1
• 12 (double 6s): Raise ST by 1

What ever the roll, you can only choose either one skill to gain or one attribute to raise.

For more information, see the Living Rulebook (page 40 deals with these rolls). The game follows these rules pretty faitfully, with some exceptions and Blitz mode spesific additions.
