About this tool

Upgrading your gear in Knight Online is a core part of getting stronger. But it's also one of the riskiest and most expensive parts of the game. Failed upgrades can cost you millions of Coin and countless hours of farming. Without a clear plan, you might end up spending more than you intended or even losing valuable items.

This Knight Online Upgrade Simulator is here to help. It provides clear estimates for your upgrade journey. You can calculate the success chance for an entire upgrade chain, predict the number of attempts needed, and get an average total Coin cost. Use this tool to make informed decisions and manage your in-game economy more effectively before you even touch the Magic Anvil.

WORKED EXAMPLE

Upgrading an Exceptional Raptor from +7 to +8

To upgrade an Exceptional Raptor from +7 to +8, you can expect around 6.67 attempts. The average total cost for this upgrade is approximately 83,375,000 Coin.

You're a warrior looking to boost your damage. You currently have an Exceptional Raptor +7 and want to upgrade it to +8. You've checked the market for prices and want to know the potential cost and success rate before you start. You plan to use Protection Scrolls to minimize risk.

FormulaExpected Attempts = 1 / Chain Success Probability Expected Total Cost = Expected Attempts × (Item Replacement Cost + Upgrade Scroll Cost + Protection Scroll Cost)
  1. 1. We want to upgrade an Exceptional Raptor from +7 to +8.
  2. 2. The tool calculates the chain success probability for this specific upgrade. For our example, let's assume the tool outputs a 15% (0.15) chain success probability when using a Protection Scroll.
  3. 3. Calculate Expected Attempts: 1 / 0.15 = 6.67 attempts.
  4. 4. Calculate Per-Chain Material Cost: 500,000 (Upgrade Scroll) + 2,000,000 (Protection Scroll) = 2,500,000 Coin.
  5. 5. Calculate Expected Total Cost: 6.67 attempts × (10,000,000 (Replacement) + 2,500,000 (Materials)) = 6.67 × 12,500,000 = 83,375,000 Coin.

This estimate shows that reaching +8 on your Exceptional Raptor is a significant investment. You should expect to attempt the upgrade multiple times, potentially needing to replace your +7 item several times if it breaks. The total cost of 83,375,000 Coin is substantial for a single upgrade level. Before proceeding, always compare this estimated cost against the current market price of a pre-upgraded +8 Exceptional Raptor. Sometimes, buying the item directly is a safer and cheaper option. Use this information to make a strategic choice for your character's progression and avoid unnecessary losses.

Limitations

  • This tool provides an estimate, not a guarantee. Your actual results will vary based on luck. You might succeed instantly or fail many times.
  • Market prices change constantly. The costs calculated are only as accurate as the prices you input. Always verify current market values.
  • The simulator does not account for special events, server bonuses, or specific character skills that might alter success rates. It also cannot predict personal luck.
  • This tool focuses on Magic Anvil upgrades where items can break. It does not cover safe upgrades or unique accessory/quest item systems.
