This calculator shows the maximum probability of achieving a completed stone that satisfies all chosen minimum and maximum values. This probability is only accurate if you select the calculator's optimal choice at every step. For basic usage:
- Select rarity tier (number of slots per line).
- Select target values for each line.
- If your stone already has filled slots, facet the grid to match it using the hammer buttons on the right.
- Click the Start button to begin calculating probabilities.
- Each hammer shows the maximum probability of achieving the goal if you facet that line next.
- Record the in-game outcome (success or failure) after clicking a hammer.
- Repeat (5) - (6) with updated probabilities.
For example, clicking Start with the default settings shows that there is a 4.81% chance of ending up with a 7+/7+/4- ability stone if you choose line one first, but only a 2.86% chance if you choose line three first.
