Editing Gladius et Aegis: Rolling with the punches (section)

===Bonus and Penalty Dice===

Before rolling, however, the GM may apply bonus or penalty dice to the roll.

Bonus dice add to the number of dice rolled, but not all of these dice count towards the overall score. Instead, a number of dice equal to the character's Attribute are kept and scored, with the highest dice only being used.

For example, of the character has a Physicality of 4 and 3 bonus dice, he would roll 7 dice and keep the 4 highest ones. A roll of 6, 5, 5, 4, 3, 1, 1, for example, would give a total of 20.

Penalty dice directly counteract bonus dice, on a 1:1 basis. For example, if a character is awarded 4 bonus dice and 2 penalty dice, then he just gets 2 bonus dice.

If the number of penalty dice exceeds the number of bonus dice, then they become additional dice, but now the lowest dice are kept. 

For example, if a character has a Physicality of 4, 2 bonus dice and 5 penalty dice, then he would roll 7 dice and keep the 4 lowest ones. A roll of 6, 5, 5, 4, 3, 1, 1, for example, would give a total of 9.
