Normal Distributed d20 Die

Normal Distributed d20 Die

Why do I need it?
As a Role-player gamer and sometimes a DM, there is always a struggle between making the game more realistic on the one hand and less complicated on the other hand.
The problem with the regular D20 Die is that the chance to get a successful role a critical failure and a critical success is equal 5% chance. Now theoretically overall if you throw the dies 100 times you will get a normal distribution and the average of all the throws will be 10.5.
I won't try to convince you that the statistic if a single die is not a good representation of reality but I think it's not.
Any way to keep the game table the same and the number of dies you throw I deseeded to change the die.

See Graphy in the description.

The die is physically a D80 so it has
