About The Combat Simulator

The Melvor Idle Combat Simulator is an advanced tool that allows you to test your character builds against any enemy without risk. Instead of relying on simple "can I idle this?" checks, this simulator calculates key performance metrics like your average Time-to-Kill (TTK), Damage Per Second (DPS), and projected kills per hour. By modeling the combat triangle and accuracy formulas, it provides a highly accurate forecast of your performance. Use it to optimize your gear, decide which slayer tasks to pursue, and understand the true power of your setup before you commit your time and resources.

How to Use

1. Enter your complete combat stats on the left, including HP, DR, accuracy, max hit, and attack speed.
2. Enter the stats of the monster you want to fight in the middle panel.
3. The results on the right will automatically update with a full breakdown of the fight.

Pro Tip

Pay close attention to Accuracy vs. Evasion. A high max hit means nothing if you can't land your attacks. Sometimes, switching to gear with a lower strength bonus but a higher accuracy rating will result in a significantly better DPS and faster kills per hour against high-evasion enemies.
