With the update to the ancestral tableau this calculator is no longer accurate, do not use the results to inform which weapons to put in your tableau.
Under the new system it does not seem complicated enough to get all cr and stats from the tableau to necessitate a calculator. As such there are no plans to update the calculator unless that changes.
If you are still having trouble with you tableau, or have suggestions for some other calculator that you would find useful please let me know through my original reddit post for this calculator.
Provide you warband's name to register. Once registered you will be given a warband code. Share your warband code with your warband members so everyone can log in and access the same data.
This site will cache your warband code automatically and it should not be needed to access your data in the calculator going forward. It is possible you may need it again if your cache is cleared or when using a new device/browser so please store it somewhere safe.
This calculator is designed to allow all warband members to input any number of ancestral weapons they may have.
The calculator makes every possible 4 weapon set out of the weapons provided. From those sets it presents the best weapons to put in your ancestral tableau. You will only benefit from the calculator if some of your members enter multiple weapons to choose from.
The goal of the calculator is find the set with the greatest likelihood of all "Max Bonus" stats being greater than the "Current Bonus". The best set will have a good distribution of stats if possible and will try to have no low values for any "Max Bonus".
The Ancestral Tableau in Diablo Immortal will select the 4 weapons with the with the highest total stats regardless of which stats they are. You may need to have some players remove or replace high stat weapons for the Tableau to select the desired weapons from the best set.
Every time weapon data is changed it recalculates the best set. This does not mean that you need to change the weapons in your tableau every time the best set changes. You only need to change weapons in the Tableau when your current bonus is going to be greater than any max stats and you will start losing CR.
WARNING: The current version uses a very streamlined way to provide all members of the warband access to the same data. In its current state if multiple warband members are editing data for the same player at the same time it may not save all of the edits properly.
This calculator is still in early development so there may be some bugs to address, UI/UX improvements, and additional features added. If no one from your warband uses the calculator for over a month the data associated with your warband may be deleted.
Hopefully your warband will find this calculator useful. This version was developed rapidly and as such there is much more that can be done to improve the system. Continued development will depend on its popularity, and available development time.
