Choose a faceting line using the stone’s current results and your target

Select an ability stone and enter the current success and failure state to compare its legal next lines. We plan to show each supported target chance while preserving impossible goals and ties.

Updating an observed result or undoing a mistaken entry will be deliberate. Stone and engraving pages will open the same calculation, and reloading or sharing will retain the exact target without implying that the website spent resources in game.
