Product Description
This is a one-hundred-one-sided die (d101) made by truncating a sphere with 101 equally-sized landing positions. The design is based on optimally packing circles on a sphere and is asymmetric.
Very similar to a d100 except you get a 1 in 101 chance of getting an "extracritical hit". This is also, to my knowledge the largest prime-sided dice currently available.
