About _NPCScan

_NPCScan tracks seldom-seen rare mobs by proximity alone, making the old “/targetexact …” macros obsolete. It has the same range as those targeting macros, but you won't have to mash any buttons. Just go about your business and let _NPCScan alert you when it finds something.

V5.x Changes
  • Due to changes in how the addon stores data, some settings might get reset when updating.
  • The default alert is suppressed while on flight paths by default. If a mob is found, the whisper sound effect will play and the mob & location will be placed in the chat log. You can turn this off from the settings.
  • _NPCScan now includes all rare mobs in the game.
  • The "One of Many", "Timeless Champion" & "Champions of Lei Shen" Achievements have been added.
  • Rare Mobs and Tameable Mobs have their own tabs now.
  • Custom mobs have been added for the Ghostly Pandaren Fisherman & Craftsman.
  • Individual mobs can be removed from their tabs to stop tracking them.

NPCScan now tracks "vignettes". These are the little skulls appear on the minimap, that denote rare mobs. This is a beta feature and is disabled by default. Enabling this feature will alert you to a rare that's within minimap range, without any worries about having to clear your cache. When you get an alert you will be shown a target button similar to the standard mob alert, letting you know that a vignette mob was detected. Clicking on the target button will try and target the mob. Once a mob is targeted, the target button will update to reflect the mob found.

Known Issues: Currently there is no way to detect what mob the vignette represents. Because of this there is no way to filter out and ignore individual mobs. The vignette tracking will ignore achievement mobs groups that have their tracking turned of via unchecking their tab. Also the targeting button might have some issues if there are more than one vignette mobs in target range.

The Cache

This addon doesn't use nameplates or mouseover units to find rares. Instead, it checks your creature cache for the moment a rare mob is found. There is one catch to this technique however: Once a mob is “found”, _NPCScan won't be able to find it again until your cache is clearedf you find a rare mob's corpse—Dirkee for example—you would have to clear your cache before _NPCScan would find Dirkee again. Thankfully, clearing your cache is a safe and simple matter.

Clearing Your Cache

To clear your cache, follow these straightforward steps:

  1. Exit World of Warcraft
  2. Delete the “Cache” sub-directory inside your World of Warcraft folder.  For example on a standard Windows XP installation, you would delete the folder “C:\Program Files\World of Warcraft\Cache”.
  • Advanced users can delete “C:\Program Files\World of Warcraft\Cache\WDB\enUS\creaturecache.wdb” specifically to improve log-in times, where enUS is your language code.

Note: Windows Vista and Windows 7 users see this info if your cache isn't in the location above.

That's it. Log in after you've done that and you'd be able to find Dirkee a second time. It's completely safe because WoW will recreate your Cache folder after you log in again.

Cache Warning

If a rare mob is already cached when you log in, _NPCScan will print a warning message with the names of those mobs. If you see this message but still want to find the listed NPCs again, it's time to clear your cache by following the above procedure; Otherwise, you can quit searching for those mobs using the Search options window detailed below. You can suppress this log-in message using the main options pane, as well.

“Found” Alert

When a rare mob is found, _NPCScan alerts you by playing a loud and distinctive sound, making your screen pulse red, and displaying an animated Targeting Button. To get a feel for what this alert looks and sounds like, try the “Test Found Alert” button in the addon's main Interface Options panel. (See the Options section below.)

Targeting Button

When clicked, the targeting button tries to target the most-recently-found mob.  You can also bind a key to hit this button. If the default button position isn't to your liking, you can move it while holding your CTRL key.

Note: The button cannot be shown during combat. In the unlikely case that you do find a rare while fighting, the button will appear after you leave combat. You will still hear the alert however, and the name of the mob will appear in your chat log.


_NPCScan's main options window can be accessed from the Interface Options menu. This panel includes a “Test Found Alert” button, various ways to customize the alert sound, and an option to suppress cache warning messages on log-in. New sounds can be added to the alert sound dropdown menu by installing SharedMedia-type addons.

Search List

The list of mobs that _NPCScan searches for can be modified easily through the Interface Options panel, however it comes pre-configured with most rare Outlands and Northrend mobs.; To access the mob list, type “/npcscan”. Grayed out NPCs in a list aren't being searched for, either because they're cached or not needed for their achievement.

The first tab available lists Custom NPCs that you can enter or remove manually. NPCs that are already cached show a red “X” in the first column. You can add or remove Custom NPCs with the [+] and [-] buttons at the bottom right.

All other tabs control achievements like Bloody Rareand Frostbitten. These tabs show an additional column on the right with green check marks for completed achievement mobs. You may enable or disable tracking each achievement with its tab's checkbox.

To remove non custom mobs from a tab, click on the mob that you want to remove and then click on the "Remove" button. This will remove the selected mob from the current tab and add it to the Ignore List Tab. If you ever want to restore a Ignored Mob, select it from the "Ignore List" tab, click the "Remove" button and it should be added back to its original tab.

The “Search for completed Achievement NPCs” checkbox at the top left of the pane allows you to keep looking for mobs you no longer need for achievements.

Finding NPC IDs

A mob's NPC ID is its unique identification number, and it can be found on sites like WowHead or WowDB For example, search for the mob “Dirkee” on WowHead and go to the mob's page.  That page's URL will look like

32500 is Dirkee's NPC ID.


The only problem mobs for _NPCScan are tamable beasts & Battle Pets. Whenever you run across the tamed version, _NPCScan gets tricked into thinking that mob is nearby. In order to prevent those false positives, _NPCScan only shows alerts for tamable mobs in their original zones That is, if you spot Loque'nahak in Dalaran instead of Sholazar Basin where it usually patrols, _NPCScan would ignore it. When one of these tamable mob false-alarms happens, you'll see a message in your chat window explaining why it got ignored.

Since this makes tamable mobs are so difficult to track, I suggest you fly to the tamable mob's zone first, clear your cache, and then search for it.; Any time you pass through a populated area like Dalaran, you risk filling your cache with popular rare pets.

For Battle Pets there is no way for it to determine if a mob is a spawn or someone's pet. Many Battle Pet addons and just opening the Pet Journal will often cause Battle Pets to become cached.

    I know it is a small technicality of just changing the version number to update the add-on and most people have no problem running "out-of-date" addons but i run over 100 add-ons and when a new patch comes out if i run all my out of date add-ons i get bogged down with errors ...

    i know nothing about making addons nor why this happens if they all just need an updated version number ... but with this many addons and many alts on a few dfferent realms ... i can spend hours trying to figure out which i can actually run ...

    i have not run NPCScan since 5.1 came out and i miss it ... please update so it is no longer out of date

    thank you

    NPCscan will not give you any errors for running it now while the game says it's out of date. So disable the ones that haven't been updated since 4.1 or something like that and then click "load out of date addons". In the case if NPCscan it's probably just a number that needs to be changed from 5.1 to 5.2 - nothing major has changed in the game files, only a few more rare NPC's were added to the game, which you can add yourself. Someone posted a link to a list with the new 5.2 rare creatures, just copy that line per line and paste into chat and they will be added to your NPCscan.

    npcscan cache rares even if you aren't in the zone?

    Question for you guys! I tried looking this up online and could not find the answer to this question. I was having problems with the cache even after deleting the file and rebooting WoW it would still have mobs cached.  Well I finally fixed this and have had no issues since. However, I've been camping Gondria (Spectral Tiger) In Zul'Drak in hopes that he would spawn at some point. Well I was two minutes to late the other night and someone else got him around 2:30AM. So I was thinking that maybe he's a 24hr mob and wouldn't be up again till around that time. So today I left the area briefly for about an hour or two to go quest. When I left Gondria was NOT cached. When I returned to Zul'Drak I got the error in chat window saying that a few mobs were now cached and Gondria was one of them. So this leaves me with the question of, If I left the zone and he ended up spawning while I was gone is it possible it cached it and that was an indicator that he has already spawned for today? Without me obviously getting the alert that he had spawned (Because I wasn't near him) Or is this just a possible bug? I removed the cache again and he is NOT cached now.


    Any help would be greatly appreciated,


    Thank you! :-)

    When rare hunter pets are cached without you having been near their spawn points (spawn zones), this is because NPCscan has picked up player pets with the same name - i.e. people taming Skoll and naming him Skoll afterward. This especially happens when you're in big cities because of the large amount of people there, that's why it's recommended to clear your cache while you're in the area you're camping. Also, NPCscan will never give a warning when it encounters rare hunter pets outside of their native (spawn) zone, so if Gondria is cached without you getting the "NPC found!" window, you have not actually encountered her.

    In short:
    - the cache is fine
    - NPCscan cannot tell the difference between a pet named Gondria and the "real" Gondria when it comes to caching
    - but it will never display an audiovisual warning if you're not in the zone the rare spawns in
    - rare hunter pets /always/ get cached when you pass places with a lot of people, so log out in the zone you're camping the tamable pet at and then clear your cache there to prevent this
    - in other words: logging out in SW <or any big city> + clearing cache + logging back in SW = pointless. Creatures will instantly be cached.
    - I guess this also applies to people naming their pets after non-tamable rare creatures. 

  • #2165

    If someone around you at any time has it as a pet, it will cache.

  • #2163

    I have gone over and over repeating the steps to delete the cache but nothing.

    When I add a custom NPC (a battle pet) to the list, it automatically puts it to CACHED right away. Then I go through this whole clear chache thing and still, I log in and he is still cached. On the other hand the rest of the creatures aren't cached anymore.

    Any ideas?

    A lot of people here are really helpless.. "How do you remove a mob? How do you delete the cache?" All things easily explained and frankly self-explanatory. Sad.

    A lot of people here are really helpless.. "How do you remove a mob? How do you delete the cache?" All things easily explained and frankly self-explanatory. Sad.

    People asking a question about something they haven't learned to do are helpless? People may be new to the game or new to addons etc, and may not know what cache is. The only thing helpless here is your snotty comment that offers 0 benefit to those looking for answers.

    To those with Windows 7 64bit  who need a simpler version of how to clear your cache just seach for or copy and paste C:\Program Files (x86)\World of Warcraft\Cache\WDB\enUS (NOTE: YOU WILL HAVE 2 "Program Files folders. DO NOT USE C:\Program Files, USE THE C:\Program Files (x86)) and delete the file that says "creaturecache.wdb". Once done NPCscan will now notify you of all NPCs that were cached (All previously scanned NPC's).

    If you are using a 32 bit version of windows you will only have 1 program files folder. Most likely the folder C:\Program Files (x86) will just be C:\Program Files without the x86 at the end. The file path should look like C:\Program Files\World of Warcraft\Cache\WDB\enUS. Just follow the above step and delete the file. Now you are good to go.

    Hope this helps.

    Would be cool if you could right click on the rare's name to show it's loot table similar to AtlassLoot. Then I'll know if it's worth killing instead of having to check Wowhead.

  • #2155

    Update Scan and Overlay please!!!
