Combat level

This article has a calculator here. For a full list of calculators available on the Wiki, see the Calculators page.

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.

	Combat Level Up!
The music that plays when levelling up.

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.

• Bounty Hunter requires a combat level of 32 , in addition to 12 hours of account play time
• Pest Control novice boat requires 40
• Soul Wars requires 40
• Pest Control minigame teleport requires 40
• Pest Control intermediate boat requires 70
• Dream Mentor requires 85
• Pest Control veteran boat requires 100

Slayer masters, by default, have a combat level requirement to get certain Slayer tasks from them, although this combat level requirement can be waived by showing them a Slayer cape. 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/Achtryn requires 20
• Vannaka requires 40
• Chaeldar requires 70
• Konar quo Maten requires 75
• Nieve/Steve require 85
• Duradel/Kuradal require 100 (and 50 )
• Mortimer requires 100 and 70 (or 99 )

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, if this total is at least 50% more than your highest level in Magic or Ranged this value will determine your combat level
   • If it is not, instead use the value of the highest level between your Magic and Ranged skills multiplied by 1.5 (rounded down)
4. Multiply the applicable value by 0.325 and add the result your base combat level for your total combat level.

Looked at another way, the formulae above effectively describe the following:

All accounts automatically get:

• +0.25 Combat level for every two levels in Prayer
• +0.25 Combat level for every level in Hitpoints
• +0.25 Combat level for every level in Defence

Which is then combined with one of the below options which is automatically whichever one results in the highest combat level

• +0.325 Combat level for every level in Attack and Strength
• +0.4875 Combat level for every level in Magic
• +0.4875 Combat level for every level in Ranged
  

Notes

• Melee-based combat level can be up to 126.
  • Once the average across your attack and strength is >75 your combat level will always be melee based
• Ranged/Magic-based combat level can be up to 109.

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

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 unique colours exist for this purpose.

Some monsters do not have a combat level despite being attackable; these include, but are not limited to:

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

• In RuneScape Classic, the maximum combat level is 123 due to an alternative combat level formula.
• In RuneScape, the maximum combat level was increased from 126 to 138 in 2008 with the release of the Summoning skill. It was then further increased to 152 in 2023 with the release of the Necromancy combat style. The maximum levels of Attack, Strength, Ranged and Magic were also later increased to 120 to match Necromancy's maximum level, however this had no impact on the maximum combat level due to how the formula is calculated.
