Combat level (2024)

This article has a calculator here. Calculators determine experience and costs based on real-time prices from the Grand Exchange Market Watch.

A player's, monster's, or non-player character's combat level indicates the difficulty in defeating them in combat. For some bosses and most monsters it is reflective of their actual stats as well.

Normally, aggressive non-player characters stop attacking you when you reach higher than double their combat level. There are exceptions, however - for example, almost any monsters, except for Rats, in the Wilderness will be aggressive no matter what your combat level is.

By default, monsters with a higher combat level than a player cannot be attacked by using a left mouse click, requiring a right click to select the attack monster option. So, to be able to attack a Blue dragon with combat level 111 with a simple left click, a player would need a combat level of at least 111. However, this behaviour can be changed in the controls section of the Settings tab by changing the "NPC 'Attack' Options" setting.

All new players start out at combat level 3, and the maximum level for players in Old School RuneScape is level 126. Players will receive a combat level-up notification upon reaching a new combat level. This can be disabled in the game settings.

Combat level requirements[edit | edit source]

• Pest Control novice boat requires a combat level of 40
• Soul Wars requires a combat level of 40
• Pest Control minigame teleport requires a combat level of 40
• Pest Control intermediate boat requires a combat level of 70
• Dream Mentor requires a combat level of 85
• Pest Control veteran boat requires a combat level of 100

Slayer masters, by default, have a combat level requirement to get certain Slayer tasks from them. Players can get more difficult tasks by asking the Slayer master to ignore combat level, though this does not bypass the minimum combat requirement to get a task from that master.

• Mazchna requires combat level 20
• Vannaka requires combat level 40
• Chaeldar requires combat level 70
• Konar quo Maten requires combat level 75
• Nieve/Steve require combat level 85
• Duradel requires combat level 100 (and 50 Slayer)

Calculating combat level[edit | edit source]

Simply[edit | edit source]

1. Take your Prayer level and divide it by two and round down (for example, if your Prayer level is 43, dividing by two and rounding down gives you 21)
2. Add this to your Hitpoints and Defence levels and divide the result by 4. This is your base combat level. (For example, if your Hitpoints is 60, Defence is 70 and prayer is 43 you should end up with 37.75)
3. Add your Strength and Attack levels together and multiply by 0.325. Add this to your base combat level and you should have your melee combat level.
4. If your Magic or Ranged level is exceptionally higher than your Attack and Strength, carry on - in the calculation noted below Magic is used, but if your Ranged is exceptionally higher, use that instead in all cases
5. Divide your Magic level by 2 and round down, and then add your Magic level again to this (for example, if your Magic level is 83, you should end up with 124)
6. Multiply this by 0.325 and add the result to your base combat level calculated above, and you should have your magic combat level.

Mathematics[edit | edit source]

${\displaystyle \begin{array}{ll}\text{Base}& =\frac{1}{4}\times (\text{Defence}+\text{Hitpoints}+\lfloor \text{Prayer}\times \frac{1}{2}\rfloor )\\ \text{Melee}& =\frac{13}{40}\times (\text{Attack}+\text{Strength})\\ \text{Range}& =\frac{13}{40}\times \lfloor \text{Ranged}\times \frac{3}{2}\rfloor \\ \text{Mage}& =\frac{13}{40}\times \lfloor \text{Magic}\times \frac{3}{2}\rfloor \\ \text{Final}& =\lfloor \text{Base}+\text{<mrow data-mjx-texclass="ORD">max</mrow>}(\text{Melee},\text{Range},\text{Mage})\rfloor \end{array}}$

Combined formulae[edit | edit source]

${\displaystyle \begin{array}{ll}\text{Melee Combat Level}& =\lfloor \text{Base + Melee}\rfloor =\lfloor \frac{1}{4}\times (\text{Defence}+\text{Hitpoints}+\lfloor \text{Prayer}\times \frac{1}{2}\rfloor )+\frac{13}{40}\times (\text{Attack}+\text{Strength})\rfloor \\ \text{Ranged Combat Level}& =\lfloor \text{Base + Range}\rfloor =\lfloor \frac{1}{4}\times (\text{Defence}+\text{Hitpoints}+\lfloor \text{Prayer}\times \frac{1}{2}\rfloor )+\frac{13}{40}\times \lfloor \text{Ranged}\times \frac{3}{2}\rfloor \rfloor \\ \text{Magic Combat Level}& =\lfloor \text{Base + Mage}\rfloor =\lfloor \frac{1}{4}\times (\text{Defence}+\text{Hitpoints}+\lfloor \text{Prayer}\times \frac{1}{2}\rfloor )+\frac{13}{40}\times \lfloor \text{Magic}\times \frac{3}{2}\rfloor \rfloor \end{array}}$

Wiki combat calculator[edit | edit source]

This calculator can be used to experiment how combat skills affect combat level.

Colours[edit | edit source]

Combat levels that are different than your own display as a different colour. These colours range from ±10 of your combat level, from shades of green for levels that are slightly lower than the player's to red for levels slightly higher than the player's; 9 distinct colours exist for this purpose.

Exceptions[edit | edit source]

Some monsters do not have a combat level. These are:

• All reanimated monsters
• Kolodion (excluding his final form)
• Solus Dellagar
• Evil creature
• NPCs of Chambers of Xeric (with the exception of the Great Olm)

Changes[edit | edit source]

Trivia[edit | edit source]

• In RuneScape Classic, the maximum combat level is 123 due to an alternative combat level formula.
• In RuneScape 3, the maximum combat level is 152 due to the introduction of the Summoning and Necromancy skills.
