You can use this feature to roll dice, if you'd like. You can choose to use either Javascript's random number generator, which is notoriously not very random; or the cryptographically secure, more random Crypto.getRandomValues() function, which can take more time. Up to you.
Enter the dice you would like rolled in the text field below. This accepts standard dice notation ("1d20", "2d10"). You can also choose whether any rolls are getting dropped.
