Combat level

A player's, monster's, or NPC's combat level indicates the difficulty in defeating him, her, or it in combat. In the very early days of RuneScape classic, players started out as Level 1 Combat, but this was changed and now all new players start out at Level 3, with the maximum level for RuneScape being Level 138, while in RuneScape Classic it is Level 123.

Combat level is calculated by taking into account the following skills: Levels that are lower than the player display shades of green, levels that are slightly lower than one's display yellow-green, levels that are equal to one's are displayed as yellow, and levels that are higher than yours display shades of orange to red. The difference in colours can be seen up to 10 levels higher or lower than your current combat level after which it will either show the brightest shade of green or red depending on whether the combat level is lower or higher.
