🎯 What is the Lost Ark Stone Calculator?

The Lost Ark Stone Calculator is an interactive tool designed to simulate the expected outcome when faceting an Ability Stone. You input the total number of slots and your success rate percentage, and it instantly calculates how many successful and failed facets you can expect.

This tool is perfect for both new and experienced players who want a fast, reliable way to estimate their chances during stone engraving.


🧭 How to Use the Stone Calculator

Using the Lost Ark Stone Calculator is incredibly easy. Here’s a simple step-by-step guide:

1. Enter Total Slots

This is the number of remaining nodes (facets) you need to fill on your stone. Typically, stones have 6 to 9 slots per engraving row, for a total of 18 or 27 slots.

Example: If you’re starting with a fresh stone, enter 27 for total slots.

2. Input Your Current Success Rate

This rate fluctuates during the faceting process. Start at 75% and decreases as you succeed, or increases when you fail. Enter the current success percentage shown in-game.

Example: If your current success rate is 55%, input that number in the success rate field.

3. Click “Calculate”

Once the values are entered, click the Calculate button. The tool will return:

  • Estimated Successes: Expected number of successful engravings.
  • Estimated Failures: Expected number of failed attempts.

4. Review Your Results

You’ll see your success/failure estimation instantly displayed on the screen, helping you gauge your odds.

5. Reset for New Try

🧠 Understanding Lost Ark Faceting Mechanics

In Lost Ark, engraving stones can be one of the most frustrating RNG-driven systems. The system dynamically adjusts your success rate depending on your previous attempts. Starting at 75%, a success will reduce the rate by 10%, and a failure increases it by 10%, capping at a minimum of 25% and maximum of 75%.

While our calculator doesn’t track live dynamic changes, it provides statistical averages for planning purposes, based on a snapshot success rate.


🔍 Who Should Use the Lost Ark Stone Calculator?

  • New players who want to understand how stone faceting works
  • Veterans looking to optimize perfect engravings
  • Streamers and content creators who want visual aids for their builds
  • Anyone tired of manually guessing outcomes during RNG-filled sessions

  4. Don’t tilt—remember it’s RNG at the end of the day!
  5. Balance success and failure to optimize both blue and red rows.
