Questions
Is the d20 fair?
Yes. Each roll is an unbiased random number from 1 to 20, so every face has a one in twenty chance.
Can I add modifiers?
Not automatically: it shows each die and the total, so add your modifier to the result yourself.
Does it have percentile dice?
There is a d10 but no linked percentile pair. For a number from 1 to 100, use the random number generator.
