- Left click a dark blue rectangle to invest level-up progress point(s) in a power rank. It will turn a lighter blue to signify that you've invested in that power rank. If you change your mind, you can simply right click the light blue rectangle to deselect that rank and refund your progress point(s).
- As a shortcut, when you left click any dark blue rectangle, the calculator will assume you want to upgrade all the way up to that power's rank. So if you clicked on rank 4, it will "fill in all the blanks," investing in rank 1, 2, 3 and 4 if you haven't invested in those ranks previously. Same situation in reverse if you want to deselect ranks.
- Red rectangles denote ranks for which you've invested points into but haven't chosen an upgrade. Ranks 4, 5 and 6 of each power allow you to choose one of two possible upgrades. Left-click on the red rectangle to initiate a popup prompt that allows you to choose an upgrade. Once you've chosen an upgrade, the rectangle will change to a light blue color.
If you ever change your mind, you can still left-click on that light blue rectangle to initiate the popup prompt again.
If you are not ready to make a choice, you can cancel the prompt by left clicking anywhere on the page except for the two choices.
- Clicking the "Save Build" button will change your browser's URL address with the new build url that you can bookmark for future reference or share with others. If you make any changes, click the "Save Build" button again to update the browser URL (it does not happen automatically).
