Link: TGM Jewel Optimizer
Hello everyone! I made a jewel optimizer for the Grand Mafia. Here’s how to use it.
First, go to files, then make a copy:


Next, go to jewel type, and click on the dropdown menu.

Select the jewel stat type you want to optimize.
Then, for that one jewel type, insert the amount of that jewel you have of all grades- including both equipped and unequipped jewels. For example, if you have 4 elite biker attack jewels and 4 rare jewels equipped, and you have 1 rare jewel and 2 simple jewels unequipped, you would enter 3 for the elite section, 5 for the rare section (4 + 1 = 5), and 2 for the simple section:

The optimizer should automatically tell you the most optimal jewel equip on the 5th and 6th line, as well as your stat boost:

And that’s it! That’s all you need to know to use this jewel optimizer!
Disclaimer: This jewel optimizer currently only works if you are going to put jewels on all 8 equipment of the set! If you plan to only put jewels on 6 of your 8 pieces of equipment for a set, this optimizer will not work! I have not added those. I may or may not add those in the future. I also manually calculated the optimized jewel equip, so there may be errors. Please feel free to leave a comment here if you notice a mistake, and I will fix it asap.
