How the combat level formula works

Two parts. A base everyone always has, plus whichever of your three attack styles is strongest. Only the best style counts: a level 90 Magic on a maxed melee account adds nothing.

How to check your combat level

1. 1

   Enter your combat stats

   Type your Attack, Strength, Defence, Hitpoints, Ranged, Magic, and Prayer levels. The combat level updates instantly as you type.

2. 2

   Or load them from the hiscores

   Enter your OSRS username and pick a table: Deadman reads the live tournament hiscores during a DMM event, Main game reads the regular OSRS hiscores.

3. 3

   Read your level and bracket

   The result shows your combat level, the exact unrounded value, which attack style the formula counted, and which Deadman bracket you sit in.

4. 4

   Plan your next level

   The fastest-routes list shows the fewest levels in each skill that add +1 combat, so you can level toward or away from a bracket boundary on purpose.

What each skill adds to your combat level

Not all combat skills are equal. Defence, Hitpoints, and Prayer count no matter what you train; Attack and Strength only count while melee is your strongest style; Ranged and Magic only count while they are on top, but they climb almost 50% faster per level when they are. This table is the whole formula reduced to per-level weights:

Skill	Adds per level	When it counts
Attack	+0.325	Only while melee is your strongest style
Strength	+0.325	Only while melee is your strongest style
Defence	+0.25	Always
Hitpoints	+0.25	Always
Prayer	+0.25 per 2 levels	Always, but odd levels add nothing
Ranged	+0.49 average	Only while ranged is your strongest style
Magic	+0.49 average	Only while magic is your strongest style

Two practical takeaways. First, a ranged or magic pure levels combat fastest of all builds: each Ranged level is worth roughly 0.49 combat when ranged leads, against 0.325 for a melee level. Second, Prayer is the stealth stat: it only ticks every second level, which is why pure builds park it on an even number and why the calculator sometimes shows Prayer as a surprisingly cheap route to +1.

Combat brackets in Deadman Mode

Deadman Mode protects lower-level players by splitting worlds into combat brackets: you can only fight people inside your own range. The permanent Deadman world uses the three brackets shown in the table above. During seasonal events the finale also splits into bracket worlds, so knowing exactly where your build sits, and how many levels you can gain before crossing a boundary, is a real strategic decision for pures and bracket campers. The exact seasonal ranges change per event; we update this page when the next Deadman is announced.

Combat level milestones

A handful of combat levels unlock things or close doors, so they are the numbers worth planning around with the calculator:

The two bracket edges, 75 and 85, are the Deadman-specific ones. A build sitting at exactly 75 fights nobody above its own level on the permanent Deadman world, which is why bracket-capped builds aim to land on the boundary and then stop gaining combat entirely. Use the fastest-routes panel above in reverse: it tells you which skills you can no longer afford to train.
