ADF-2D-10 フラットドリル ADF-2D

2d 10Probability of getting 1 10's is close to 0.1, about 10% percent. This is calculated by multiplying together all the probabilities of getting a 10 for each dice that has a 10.Also it's faster and easier to balance. Not many people have good intuition around normalgaussian distributions (and 2d10 is a triangle anyway)
