This is the die Hermes Trismegistus never mentioned in Corpus Hermeticum.
This D20 Dice has 19 alchemist signs and one "Void" instead of numbers.
You can make your own chart for the value of each sign.
In the images above you can see the chart my personal alchemist gave me. ;)
The D20 of my
Fractalic Mystical Dice Set is made out of a kaleidoscopic iterated function system icosahedron..
Created by Nature itself - By Fractal Mathematics.
