Introducing: SW Roll Calculator. A tool to compare and visualize outcomes of Trait Rolls

Resources / Tools

Hi everyone,

I've built a tool to compute and display the probabilities of various Savage Worlds rolls. Currently it only does trait rolls, but you can at least visualize for yourself, what is really better: +2 or free reroll. (Spoiler: Starting at d8, +2 is always better, unless you need A LOT of raises or have a penalty >4 on your roll D8+2 in blue, D8 with 1 free reroll in green).

For Windows you can find the tool here.
For *nix Users you can build yourself, using the source code from my github.

The programm is released under GPLv3 so feel free to share it around.

Any feedback is welcome here!

What special roll cases should I integrate next?

Simple dice probabilities are neat but already handled by other tools. What I would really be interested in would be some more with cards. Dealing with the devil poker hand probabilities for Deadlands the weird West (not reloaded), comparison between quick and level headed, joker probabilities with certain edges, the statistical value of edges that give a bonus when you have a joker, especially when combined with edges like level headed or even hesitant. That stuff would be awesome.

Cards shouldnt be too difficult to put in for me, the only issue I see is visualization. But I'll see what I can do.

The 2nd bar is for Fails that are not Critical Failure. I.e. the roll result is <4, but not both dice came up 1.

That means to roll a 3 on DX+2 (including Wild Die) you have to Crit fail. So a Fail that is not a Crit Fail is impossible (0 probability).

He means that the only outcome is both die show 1. All other outcomes is a success. So there is no fail only critical fail.

Very cool! I've been wanting to make something just like this but never got around to it. I'm glad you put in the work to make this.

If I can suggest future features, I'd like to see the option for multiple trait dice, looking for n successes. In my game, multiple actions aren't penalized, you just roll an extra die and can use the wild die to replace either of the skill dice. The rule works so far, but I'm curious about its exact boundaries.

Multiple Trait Dice is definitely on the agenda, esp. since they are also relevant for things like Ranged Attacks with RoF>1.

The biggest issue I have with them is multiple Trait Dice AND rerolls. Because with multiple dice, you wouldn't always go for the highest number of successes and raises. If at RoF 3 you got one roll with 15 Raises and two fails, you wouldn't pick that over a Roll with two times 1 Raise and one Success.
