FAQ

Why are my rolls always low?
That's just bad luck! In a true random system, streaks happen. Humans naturally look for patterns where none exist. (Or maybe your character is cursed).
Can I make a custom die (e.g. D50)?
This tool supports standard presets. For non-standard ranges, use the "Number Generator" tool which allows setting arbitrary min/max limits.
