Well, electronic bones, actually.
(Skip the text and jump straight to the Exalted Dice Roller)
Exalted (3rd Edition, from Onyx Path) uses a reasonably simple dice structure. Add your Attribute and Ability, roll that many d10, and any that come up 7+ are Successes. Compare your number of Successes against the Difficulty to see if, and by how much, you beat it. Nothing to it.
But … firstly, if you roll a “10”, it counts double. No trouble. Then, you get into the realm of Charms (Not Spells. At all. No. A foolish mistake. Mystical Abilities, maybe. But NOT Spells!). These can double other numbers (from 9 down to 7), allow you to reroll some dice (e.g. “Reroll any “1”s until you have no “1”s left“), add Automatic Successes on top of any you roll, add extra dice (sometimes capped by your Attribute + Ability, sometimes not) and other effects.
As your characters are Favoured of the Sun God, you can end up rolling quite a few dice (A common roll in your Prime area could be Attribute 5, Ability 5, doubled by basic Charm, plus 1 for a Speciality, and 2 Stunt Dice for a nice description: 23 dice!). Assuming you have 23d10, you may then need to reroll some of these, and then count up all of the Successes (remembering to Double 10s, and maybe others). Still with me?
As this can become quite cumbersome, I decided to test out my coding skills, and put together an Online Dice Roller!
You enter how many dice you wish to roll, along with any Specials, such as Stunts, Rerolls, etc, and “CLICK!”, the Dice Faeries on my web-server roll (and reroll) the dice, add them all up and present the result!
I have tried to include all of the common adjustments, and for those of you who have a Character registered in the TNP database, you can call upon a roll by Attribute/Ability, without having to remember what scores you have!
Why not try it out, and see if your game would benefit!
