Questions

What is the average roll of 4d8?
The average of 4d8 is 18. Each d8 averages 4.5, and 4 of them add up to 18. Totals near the middle of the 4 to 32 range come up far more often than the extremes.
How do I add a modifier to 4d8?
Type the full expression in the dice notation field, for example 4d8+5, and press Roll notation. The total shown includes the modifier, and the dice are still listed separately.
Is this dice roller free?
Yes. Every tool on Tools and Taverns is free, with no account, signup, or roll limit. The roll runs in your browser and nothing is sent to a server.
Can I see my previous rolls?
Yes. The roller keeps your last 20 rolls on screen with the individual dice for each, so a contested result is still there when someone asks what you got.
