Base Combat level

why would you calculate something times 100, something else times 50, then put 4 of them together and divide by 400? thats dumb. that would mean: (a*100+b*100+c*50+d*50)/400

you can shorten that...:


that would be much easier... or if you want


but why adding another 0 everywhere? thats kinda dumb realy...

NPC combat level formula

Is it known how the combat level of the NPCs is computed? Do they have att/str/def levels and do these levels determine the combat level of an NPC with a similar formula? 08:50, May 18, 2010 (UTC)


The section stating that combat levels indicate someone's trustworthiness is biased and should be either removed or rewritten. Opinions please. Shadowdancer 05:19, 4 August 2006 (UTC)==

I say we keep it. It is fine as it is unless someone wishes to change it a bit. Hopefully they will be alittle more accurate in some people's minds. It's all we got now. Just leave it. —The preceding unsigned comment was added by (talk).
It is an inaccurate statement. Shadowdancer 05:43, 4 August 2006 (UTC)
It's a statement about an opinion! Do you think that not many people belive that high combat level players are more experienced and honest? I think that that is a prevailing opinion, and should be noted in this article. However, if it annoys you than get rid of it. -- Couchpotato99 20:17, 4 August 2006 (UTC)
I can rewrite it sometime.-- 14:56, 5 August 2006 (UTC)
Well, I personally think it's neutral. Lower-level players probably try to scam you more often and mostly for items, while higher level players can be much more skilled at scamming and most probably scam through the wilderness.
Trustworthiness in trades has very little to do with combat level. The sanction on bad trades and scamming by Jagex is the banning of an account. A higher level player has more time invested into traing the character, so the sanction is likely to have a bigger impact. Yet, even high level accounts get hacked, others just don't care. As combat levelling is not that hard compared to training some other skills, the same deterrent applies to pure skillers with high skill levels. --Miw 14:47, 15 December 2006 (UTC)
I agree, trustworthiness has little to do with combat level. Seeing as we all seem to have agreed (by majority) that the statement is largely incorrect, can't we just delete the section? --Raven110283 14:18, 16 December 2006 (UTC)
Made an attempt to put more neutral text in the comment section. --Miw 13:44, 21 December 2006 (UTC)
From my experience, the most un-trustworthy people are the mid-levels and the level 3's. People level 70 and above don't do scam. So I think that statement is somewhat true. 04:03, 13 March 2007 (UTC)


Hi, there. I have come across the use of our combat level formula on this page, which is always something I like to see. Please bear in mind though, that I specifically requested in my thread on the official RuneScape forums, that any reproduction of the formula, is accompanied by a visible acknowledgement of its creators. I have previously editted it in, but the page was reverted by someone else. Unfortunately, people on the internet have been copying our formula (previous versions of it), without any trace of our names. In some cases, the users even claimed it their own! This behaviour was caused by uncreditted reproductions of our formulae being scattered across the internet, and so, people weren't aware that we had created it, and copied it on and on, without any references to us being present along with it. For this reason we ask that the acknowledgement the formulae's creators is maintained (not just here but anywhere on the internet), by creditting its authors in the way described in my thread on the RuneScape forums. I will re-edit it in, please leave that piece as it is. Thanks! --MaxWaterman 23:37, 17 January 2008 (UTC)

I think that it is difficult to prove that they directly copied your formula. In addition material uploaded is per the GFDL - we don't sign the additions we make the pages, so neither should we be giving copyright. Either it's released as per GFDL or not. I'm going to remove it to the talk page until this is cleared up. (Done) King Runite1 09:05, 9 June 2008 (UTC)
It depends on the case whether or not it's difficult to prove that they copied the formula. Of course, there isn't always 100% proof, but sometimes it's obvious. Whenever we make updates to the formula and they appear elsewhere shortly afterwards, with the same coëfficients, then I strongly doubt it would be coïncidence. Also, I was under the impression that the GDFL allowed at least a visual acknowledgement of its author(s). Perhaps I may have misused the word "copyright". I meant to say that the formula can be freely distrubuted under the circumstance that the authors are clearly visibly acknowledged. I believe that is in accoordance with the GDFL. If not, then please remove the formula details from this page. Thanks. MaxWaterman 11:11, 13 June 2008 (UTC)
I have linked credit to here, I think it is the fair thing to do without any proof being forthcoming.

As requested by the adventurers, which discovered this Combat Formula the following reproduction note has to be added:

“You are allowed to use this formula for your fansite, calculators etc., under the condition that you credit its creators, by writing the names of the Combat Formula Crew, clearly visible on the page where the combat formula is used.

Additional note: Please bear in mind that the concept of "odd summoning/prayer levels don't count", is what identifies our formula. If you use this concept, then you are using our formula, for which you need to credit us as well. I assure you no one has come up with this idea at the same time as us, so it is unlikely that people have found out about this on their own. If you hear about this concept it is very likely coming from us. Crediting is required in this case. Claiming you came up with it on your own is not a reason to not credit us. Our idea is several months old.

--Degenret01 08:00, 4 May 2009 (UTC)

If your formula really is accurate then its not your formula, it's RuneScapes, and all you did was reverse-engineer it. Also, saying that everybody has to credit you even if they came up with it on their own is just plain silly, for the same reason that this is a RuneScape formula that you are recreating.
This is all just a load of unwarranted self importance. I say delete all this bullshit

Calculating combat level

Original formula by MaxWaterman, Fern1970, Helcaterian, Oblivion590, Hans980 and Benmarchant.

  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. Take your Summoning level and divide by two and round down (for example, if your Summoning level is 23, dividing by two and rounding down gives you 11). This only applies to Members. If you were a member and are not anymore, you will not have this skill used to figure out your levels (you will use 1 rather than your Summoning level).
  3. Add both these numbers 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, Prayer is 43 and Summoning is 23 you should end up with 40.5)
  4. 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.
  5. 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
  6. Multiply your magic level by 1.5 and round down (for example, if your magic level is 83, you should end up with 124).
  7. Multiply this by 0.325 and add the result to your base combat level calculated above, and you should have your magic combat level.


Base = 0.25(Defence + Hitpoints + floor(Prayer/2) + floor(Summoning/2))

Melee = 0.325(Attack + Strength)

Range = 0.325(floor(Range*1.5))

Mage = 0.325(floor(Magic*1.5))

Final = floor(Base + Highest of Melee, Range or Mage)

Combat lvl Calculator - Incorrect

The combat calculator is incorrect. your combat level is JUST the first bullet point - my combat level and my friend's combat level fit the first bullet point.

Options for a Wiki Combat Calculator

The Template:Combat is an alternative to the combat calculators from other fan-sites. It uses the formulae from the Combat level description. Inserting a calll to the template on the page itself, allows players to edit that paragraph, enter their combat skill levels and observe the resulting combat calculations. The only problem is that this produces lots of edits to the page. Perhaps it is possible to set-up a sandbox with default content that calls the template. User edits would hopefully not interfere with the Combat level page itself. Unfortunately, there is very little information on how to set-up a small Sandbox area or a Sandbox page. --Miw 15:47, 15 December 2006 (UTC)

Just noticed that the Template has been used as combat calculator. In order to prevent such use, i have added a Combat template call in this page with instructions on how to use it without disrupting the Log. An automated cleaning option would be preferable though. --Miw 18:50, 15 December 2006 (UTC)

Summoning addition

They've announced that following summoning the max combat level is going to be 138. This looks like it'll just be a change to the base combat formula ie

Currently it's... Base = 0.25 (Defence + Hits + floor(Prayer/2)) It'll probably be... Base = 0.25 (Defence + Hits + floor(Prayer/2) + floor(Summoning/2))

This would give a maximum base combat level of 74 and a maximum combat level of 138.35. If this works out, then you will actually achieve combat level 138 at summoning level 96, assuming other combat skills are at 99.

Needs testing when it comes out. --Eucarya Talk 14:42, 21 December 2007 (UTC)

Use Maths instead of Code

In the Mathematics section, the <maths> tag should be used instead of <code>. For the tag description and syntax look at the Wikipedia page here: [1] --GreatEmerald 16:01, 17 January 2008 (UTC)

combat 138 for free players

The summoning maths also applies to non-members. But they cant train it so they dont get higher then 126.
Members can train summoning, so the maths applies to members to raise combat.
Buzz (Talk#P ) 12:47, 26 February 2008 (UTC)

Need to check this, but my understanding was that the combat level excluded the summoning when in non-member worlds. So, even though I am member with 40 summoning, when I am in a non-member world, my combat level will be lower than in a member world. Amaurice talk 12:54, 26 February 2008 (UTC)
This is true. At least in experience it is. I've been to a non-member world and my combat level dropped by 1.

How many 138s

anybody know how many 138's there are to date it would be intresting to see how many there might be. --Defence cape (t) Rabbit FearArmadyl godsword 00:04, March 18, 2010 (UTC)

It would be basically impossible to calculate this, especially once you consider that there are quite a few 138s with 1700 or less total level. HaloTalk 00:13, March 18, 2010 (UTC)
It could be done, but I pity the poor soul who does it, and I expect it'd be out of date a few hours after he'd done it, as it changes daily. Would be nice to see Jagex make a 'Combat Highscore', of some sort, so we could see what's the most common level, and how many of each level there is, but really, I expect it would be level 3 - 5 at the top, as people get bored, quit, never play again. TzTok-Gas talk 09:54, July 14, 2010 (UTC)
I never said it couldn't be done. To do it efficiently, you would need a bot that check hs, users to calc combat (or just has all possible minimum parameters for 138). From there it would need to search though hiscores, probably starting with players who have the minimum summoning/prayer as those are slightly rarer than melee capes. There's just tons of clan chat, on my friend's list, random people I come into contact with...User:Haloolah123/Sig 09:59, July 14, 2010 (UTC)
On estimate there are probably around 14500 138's in runescape. This is an estimate based on the amount of people with 99 summoning.

Use the easier version of the formula?

As pointed out earlier on the talk page, an easier version exists:

Base = 0.25(Defence + Hitpoints + floor(Prayer/2) + floor(Summoning/2))

Melee = 0.325(Attack + Strength)

Range = 0.325(floor(Range*1.5))

Mage = 0.325(floor(Magic*1.5))

Final = floor(Base + Highest of Melee, Range or Mage)

This is much easier to use than the mess of variables and pointless calculations that's on the page right now. Additionally, it's basic enough such that no "basic" formulas are necessary at all. As for combat levels in free worlds, a note could be made to not include summoning in the formula.

Should I (or somebody else) go ahead and do this, or are there reasons that the longer version is still on the page? It seems like many people have looked over the easy version and dismissed it, so...
Jamesa7171 20:22, July 12, 2010 (UTC)

It's fine now. Sometimes longer is better. It gives a lot more details, which can be helpful with something like this. User:Haloolah123/Sig 20:27, July 12, 2010 (UTC)
"Sometimes longer is better" - true, but I don't think this is one of those cases. I disagree with "it gives a lot more details"; the formula I posted is the exact same formula as the one on the page, just with fewer calculations involved and thus less time spent. Additionally, like I said earlier, it could take the place of all three formulas that are currently there, shortening the article by quite a bit. Jamesa7171 07:45, July 14, 2010 (UTC)

quiet before the swarm also has a combat level requirement, making that 3 quests requiring combat requirements.

This formula will never let ranged or magic get max combat level, only melee will. Using 1.5 for each will only give you 148 max where the melee attack+strength will give 198. The new calculator with the 200 max will easier to use. 15:00, August 11, 2012 (UTC)Kindiin

Combat levels- all relative?

On this wiki, I have seen no end of refferences to low, medium, high, very high, etc combat levels. I have seen no refferences to what is meant by that, although on occasion, this wiki has also given more specific requirements/recommendations, but these are not enough to understand what is generally meant by these terms. Can anyone help? Banak 10:48, May 19, 2011 (UTC)

Combat Calculator

Why don't we set up a little coded calculator to allow players to enter their levels, and the calculator tells them what their CB level is, or what it would be after they finish/achieve their goal level?

Zamorak godsword detail techguy1001Talk 23:18, January 14, 2012 (UTC)

ranged or magic?

does magic raise your cb lvl or rnged?

why is it that sometimes its rnged and sometimes its mage? 12 march 2012

Whichever is highest. --Henneyj 06:54, March 12, 2012 (UTC)

Combat level 139?

In the picture of the "punchbag" and the "devastator". it has the number 139 above their weaknesses (Magic to the puchbag for being in bandos armour and ranged for the devastator for being in mage armour). However in the "behind the scenes - fish flingers and combat abilities" the punchbag had a combat level of 2 and even in "behind the scenes - combat buffs & weaknesses and the crucible" it is said that it still has lvl 2 combat (at 4:50 in the video). perhaps the number means something else?<>< fish4fally ><> 11:01, June 11, 2012 (UTC)

Also revealed in the "og blog - tradition and change" combat levels will now have a maximum of 200

"We’re also changing the way that combat levels are calculated. We are scrapping the current 138 max design and replacing it with a calculation that’s far simpler to understand:

X + Defence level +2 = your Combat level. (X = your highest stat level from Magic, Ranged, Attack or Strength).

This makes the new max combat level 200!"

Calculator for monsters

After looking in confusion at Kree'arra's levels and combat level (courtesy of the duel cards and infobox) I decided to check the levels with a calculator.

With the below equation I only got a combat level of 578.3. This is with the levels on the duel card and the 255 constitution for the 2550 hp. The 2 800s are prayer and defence, which would mean Kree'arra had defence of 800 and prayer of 1600.


This makes me think that there is a different combat calculator for monsters, or maybe just bosses. Can someboidy check this please? Duck171 15:59, June 17, 2012 (UTC)

A combat level glitch?

Here's my stat:

Attack: 73 Constitution: 74
Strength: 74
Defense: 73
Ranged: 64
Prayer: 58
Magic: 75

When I levelled 1 defense from 72, I got a message "Congratulations! Your Combat level is now 200! You've achieved the highest combat level possible"

The new Jagex formula only gives me 150 combat level. Is this a glitch? 09:12, November 24, 2012 (UTC)

Crazy high levels

I need to know, guys, why some people, even though the max level SHOULD be 200, have combat levels of, 1000, 2000, etc etc. I know I didn't just 'see wrong' because of a guy with level 1638, and others. How do people do this?!

Vampire out 06:45, March 29, 2013 (UTC)

That's not combat levels.
If someone has their weapons sheathed, they display their total level. If they have weapons drawn, they show their combat level. Small recharge gem AnselaJonla Slayer-icon 06:51, March 29, 2013 (UTC)

Combat Level

Just wanted to give the formula for someone to put in soon for Legacy.

Summoning doesn't count towards level in F2p servers.

If Magic x 2 is highest total: ([1.3*{mage*2}]+def+HP+[pray/2]+[summ/2])/4

If Ranged x 2 is highest total: ([1.3*{range*2}]+def+HP+[pray/2]+[summ/2])/4

If Strength+Attack is highest total: ([1.3*{att+str}]+def+HP+[pray/2]+[summ/2])/4  —The preceding unsigned comment was added by (talk) on 18:26, July 14, 2014 (UTC).

Summoning "+X"

Something I've been trying to find out and should probably be added (or explained better):

1) When a user is not using summoning and their level is therefore shown as "X+Y", is their effective level X or X+Y? ie: two users are in level 20 wilderness. One is not using summoning and is shown as "110+5". The other is using summoning, but has a low summoning skill and has a combat level shown as "93" (92 without summoning, +1 with summoning). Can they attack each other? What are the two values being compared? 115 vs. 93? 110 vs. 93?

2) If a user dismisses their familiar and drops all pouches while already in the wilderness, will it instantly update from "115" to "110+5"? Does this affect the level range of opponents that can be fought?  —The preceding unsigned comment was added by (talk) on 03:18, July 18, 2014 (UTC).


Why don't you get notifications when you go up a combat level anymore?
