How it works
A single die averages one more than half its sides. The average of all the dice is that figure times the number of dice, plus any bonus.
The lowest total is every die showing one, plus the bonus. The highest total is every die on its top side, plus the bonus.
Worked example
2 dice with 6 sides and a bonus of 3 average 10, with totals from 5 to 15.
Questions
What does the number before the d mean?
It is how many dice you roll. The number after the d is the number of sides on each die.
Is the average the roll I am most likely to get?
Not always. The average is the middle of all the possible totals, and totals near it come up most often.
Can the bonus be negative?
Yes. Type a minus sign, and the average and the range both shift down by that amount.
