About This Tool

The biggest fear in Melvor Idle is returning to the login screen to find your hardcore character has died. This tool eliminates that risk. By calculating your effective HP, damage taken, and post-healing survivability, it gives you a clear "Yes" or "No" answer to the question: "Can I idle this?" Use it to push into more challenging dungeons, farm monsters with confidence, and ensure your overnight progress is safe. It's an essential utility for any player, from beginner to end-game, who wants to maximize their AFK time without worry.

How to Use the Calculator

1. Enter Your Stats: Fill in your total Hitpoints, your complete Damage Reduction percentage, your Auto Eat threshold HP, and the healing value of the food you're using.
2. Enter Monster Stats: Input the maximum hit of the strongest monster you are fighting.
3. Check the Result: The dashboard on the right will instantly update, telling you if you are safe and providing a breakdown of why.

AFK Survival Tip

Your Damage Reduction (DR) is the single most important stat for safe idling. Even a few extra percentage points of DR can dramatically reduce incoming damage, making previously dangerous monsters completely safe to farm. Always prioritize DR gear over offensive stats for long AFK sessions!
