Enhanced Attribute Bonus Die Rules
By: Dustin M. Ramsey
To qualify for an attribute bonus die, the attribute rolled must be higher than 84% of the maximum roll possible (Example: on 3D6, the average die roll is greater than 5).
The 'bonus die' that you get depends on how many dice you rolled. As such, characters getting a bonus on a 1D6 attribute (which happens 16.6% of the time) are going to get a bonus that is proportional to their attribute, and folks receiving a bonus on a 4D6 (which happens less than 1% of the time) roll is going to a proportionally larger bonus. The size of the bonus is formulated by making a ratio between the attribute being rolled and the base (which is 3D6, as supplied in the books). [In other words: this means that a 1D6 roll would have a bonus 1/3 the size of a 3D6 roll.]
The number of bonus dice you get, is equal to the number of dice you rolled for the attribute. [This uses that Conversion Book rule that if you roll a 6 on an exceptional attribute roll, you get another exceptional attribute.]
The end result is that the harder it is to get the exceptional roll, the more potential gain you have (so as difficulty goes up, so do the rewards)! This means that if you manage that one-in-a-million exceptional roll on a 6D6 attribute, you are going to get more than a lousy 1!
