This tool helps you optimize your Ability Stone selections in Lost Ark by calculating the best possible outcomes.

## Lost Ark Ability Stone Calculator

This calculator helps you determine the overall success probability of engraving an ability stone in Lost Ark based on the success and failure rates of each individual ability.

### How to Use

- Enter the success and failure rates for each ability in the respective fields.
- Click the “Calculate” button.
- The overall probability will be displayed in the result field.

### How It Calculates

This calculator takes the input success and failure rates for three abilities. It then calculates the average success and failure rates. The overall probability of successfully engraving the stone is computed using the formula:

*Overall Probability = (Average Success Rate) / (Average Success Rate + Average Failure Rate) * 100*

### Limitations

- The calculator assumes each ability has equal weight in the overall probability calculation.
- Results are approximate and do not guarantee actual in-game outcomes.
