What are High Variance Dice?
High Variance dice are dice that have been shifted to exaggerate extreme results, without sacrificing the overall average value of the rolls. For example, on a typical d6, you have the numbers 1, 2, 3, 4, 5, 6. The average roll is a 3.5. On a High Variance d6? 1, 1, 3, 4, 6, 6. The average roll is STILL a 3.5, however your chances of great success – or massive failure – have just doubled.
Each die in the set has the same concept applied. The result? A set of dice designed for those situations where characters are really headed for one of only two things: a glorious victory, or a crushing defeat. Either way, it'll be something the party will never forget.
