RS3 Combat Level Formula

The calculation relies on determining the player’s ‘Base Combat Level’ from their highest offensive stat (Attack/Strength, Magic, or Ranged) and adding proportional contributions from defensive and utility skills.

Combat Level = (1.3 × Max Combat Stat) + (0.25 × Def) + (0.25 × Con) + (0.125 × Pray) + (0.125 × Sum)
Where: Max Combat Stat = $\max(\text{Att} + \text{Str}, 2 \times \text{Mag}, 2 \times \text{Rng})$ Formula Source: RuneScape Wiki | RS Community Guide

Variables

The following skill levels are required for the calculation:

  • Attack (Att) & Strength (Str): Used to calculate the Melee combat effectiveness.
  • Magic (Mag) & Ranged (Rng): The levels for these are doubled when comparing for the maximum combat stat.
  • Defence (Def): Determines defensive capability.
  • Constitution (Con): Represents Life Points, a major factor in combat level. *Note: Use your actual Constitution skill level (often 10-120).*
  • Prayer (Pray) & Summoning (Sum): Utility skills that contribute a smaller fraction (1/8th) to the total level.

What is RS3 Combat Level?

The Combat Level in RuneScape 3 is a single numerical representation of a player’s power and skill in combat. It dictates which monsters are aggressive and serves as a benchmark for comparing players in minigames and PvE encounters. The maximum Combat Level is 138, achievable by reaching level 120 in all core combat skills (Attack, Strength, Defence, Magic, Ranged, Constitution, Prayer, Summoning, and Herblore/Invention contribution, though this calculator focuses on the primary formula).

Unlike Old School RuneScape, the RS3 formula heavily emphasizes the highest potential combat style (Melee, Magic, or Ranged), ensuring that players who focus on a single style are not penalized. This design choice makes the leveling experience more streamlined and balanced for modern combat.

How to Calculate RS3 Combat Level (Example)

Follow these steps using the formula above to manually verify a combat level:

  1. Determine Melee Stat: Add Attack and Strength levels. (e.g., 90 Att + 90 Str = 180)
  2. Determine Magic Stat: Double the Magic level. (e.g., 99 Mag * 2 = 198)
  3. Determine Ranged Stat: Double the Ranged level. (e.g., 99 Rng * 2 = 198)
  4. Find Max Combat Stat: Take the maximum of the three results (180, 198, 198). Max = 198.
  5. Calculate Base Combat: Multiply the Max Combat Stat by 1.3. (e.g., 198 * 1.3 = 257.4)
  6. Add Defensive/Utility Contributions: Add the fractional contributions for Defence, Constitution, Prayer, and Summoning.
  7. Final Result: Sum the Base Combat and the contributions. The result is always rounded down to the nearest integer.

Frequently Asked Questions (FAQ)

Is the max combat level in RS3 138?

Yes, the maximum combat level in RuneScape 3 is 138. This is achieved by having all relevant combat skills (including virtual 120s or actual 120s where applicable) at their maximum effective level for the formula.

Does Invention or Herblore count towards combat level?

Yes, both Herblore and Invention contribute a fractional amount to the combat level, similar to Prayer and Summoning. However, this base calculator typically omits them for simplicity, as their contribution is minor and not always included in the most basic formula presentations. For a precise 138 level, they are required.

What is the difference between RS3 and OSRS combat formulas?

The OSRS formula is simpler, based only on Attack, Strength, Defence, Hitpoints, Prayer, Ranged, and Magic. The RS3 formula is more complex, including Constitution, Summoning, and emphasizing the highest offensive style over an average of all combat stats.

Why is Constitution level sometimes entered as 10 times the actual level?

The in-game display for Life Points (HP) is 10 times the Constitution skill level. For the combat formula, you must use the actual Constitution skill level (usually 10-120), which is why the input box expects the skill level.
