About _NPCScan

_NPCScan helps you find rare mobs through the use of dynamic target macros, mouse over alerts and for Vignette mobs proximity. Once a mob is found by one of these methods an on screen alert is displayed, in addition to an audio alert.

_NPCScan & Warlords

Due to changes in how the game caches mobs in WoD, it is looking like _NPCScan will no longer be able to auto detect non-Vignette mobs. Due to this the only way to find pre-MoP rares via _NPCScan will be via mouse over, nameplate, or the new dynamic target macro keybind being added. The new keybind will trigger a /targetexact …” macro that updates with tracked mobs based on the zone you are currently in. Vignette mobs will still automatically trigger an alert when the mob gets in range, and should work more reliably due to updates to the Vignette API.

V6.x Changes
  • Cache Scanning Removed - Due to changes in the way WoW cache mobs, NPCScan can no longer auto alert when mobs are nearby like it use to.
  • Dynamic TargetExact Macro Keybind - NPCScan now has a keybind you can set that will try to /exacttarget tracked mobs. This macro will dynamically update based on the zone you are in and which mobs are being tracked.
  • Updated Vignette Alerts - Vignette Alerts are now more reliable and show the actual mob when detected the majority of time.

If you have a question check the FAQ, or a problem create a ticket

If you have a question/comment about _NPCScan.Overlay please post it in it's comment section.


Dynamic Target Keybind

NPCScan now includes a keybinding that will trigger a stored dynamic target macro. Each time it is pressed, the keybind will trigger a /targetexact <mob name> for every tracked mobs in the current zone you are in, in addition to any custom added mobs. This macro will be auto updated based on the zone you are currently in. To access this feature, just set a keybind under the Key Bindings->Addons->_NPCScan->Dynamic Target Macro section. Note: To search via the keybind, you will need to continuously push the bind. Pushing it once will only trigger it once, it does not auto scan like it did Pre WoD.


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.


If you have nameplates turned on, NPCScan now has the ability to trigger alerts off them. This method is not completely reliable as it has to rely on name comparison, so if mob name that NPCScan has does not match it will not trigger an alert. Also the range is limited as you need to get close enough to a mob to have the game display its name plate.

Addons that modify nameplates may interfere with this.

“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.&nbsp; 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 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.&nbsp; That page's URL will look like

32500 is Dirkee's NPC ID.

    Coukl you make it use TomTom? I flew over an NPC when I was on a route and when I tried to find the npc after landing I could not find it anywhere. I guess showing the coordinates would also be ok.


  • #2038

    I second the suggestion.

    It could be an option to record the player coordinate at the moment that a NPC is found, maybe in the chat message.

  • #2032

    To use after 5.1, do the following:

    1. Log in

     2. Click the "AddOns" button

    3. Select the "load out of date addons" option



  • #2035

    Yes, but it still does not detect any rares, even after clearing the cache and doing a complete re-install of the addon :p

    —That depressing moment when you spill your cocaine in the snow.

  • #2039

    Also having the same problem and the path is correct etc. Just doesnt trigger.

  • #2037

    The addon is working

    Maybe your problem is the one pointed in the descripcion

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

  • #2031

    After installing this, I found that the custom list only has a small number of NPCs. Where can I find a complete database of all rare mobs without having to manually enter them in?

  • #2030

    I cant use npcscan after 5.1??Anyone?

  • #2028

    UPDATE IT !! Yell

  • #2027
    Items too??

    Can I also track Items in NPCScan?? or just NPC's?

  • #2029

    Just NPCs.

    There is no way to track objects via Addons, it is possible with external applications but they are not allowed by Blizzard.

  • #2023

    Continuing the Blodaks's post for auto clear cache, I'll show you the bat that I use for delete cache when I start wow; the main difference is that with the Blodaks's command you don't need to specify the location of the NPCs cache file, making it simpler, but since it searches in the subdirectories for the file you specified is slower, if you take the time to put the specific location of the file then you can save a couple of seconds each time you open wow (depending of your computer of course).


    Creating a file to auto-delete cache and open Wow for Windows:

    Summarized guide:

    Open the folder where is installed your Wow, create a new .txt file and put this code:

    erase Cache\WDB\enUS\creaturecache.wdb
    start Wow.exe

    Correct "enUS" in case you use other language and Wow.exe in case your launcher has other name (if it has spaces put the name inside quotation marks: "name of the file.exe".

    Now save the file and change its extension to .bat, now you can do a shortcut to it and it's done.

    Step by step guide:

    1. Open the folder where you installed wow (usually found in C:\Program Files\World of Warcraft\ or C:\Users\Public\Games\World of Warcraft).

    2. Here create a new txt file, name it how you want, it doesn't matter but you could name it as "Wow.txt" (without quotes) just to make it easy to identify.

    3. Open the txt file with a text editor (like notepad) and copy this:

      erase Cache\WDB\enUS\creaturecache.wdb
      start Wow.exe

      Where it says enUS replace it with the code of the language that you use.
      If for some reason your executable has other name, replace it instead Wow.exe, for example, for 64-bit users it should be WoW-64.exe

      You can use the launcher instead, in that case you need to put:
      erase Cache\WDB\enUS\creaturecache.wdb
      start "" "World of Warcraft Launcher.exe"
      Replacing enUS or the executable file in case you have other names installed for them (see note above).
      Here the quotation marks are necessary since the executable has spaces in its name, and when we use quotation marks in the command start, MS-DOS could interpret our file name as a parameter for the tiltle of the new window and will not run our program, so we give it an empty string quoted: "" , that way we avoid problems.

      Optionally, if, for some reason, you want to delete the whole Cache folder with all its subdirectories (instead of just the NPC cache file) each time you run this bat, then you need to put:
      rd /s /q Cache
      start Wow.exe
      Changing Wow.exe for the name of your executable in case that you need or for the launcher executable name if you want, as described above.

      [External link: list of MS-DOS command], in case you want to know what exactly they do.

    4. When you are ready save the txt file and close your note editor.

    5. Now change the name of your file, probably named Wow.txt for Wow.bat (or any name you want but with the .bat extension), it will ask you for confirmation, just press yes.
      If you are unable to see the file extensions then you need to put them visible in the folder options window [How to: for Windows 7].
      If you can't see the option to unhide the file extension then probably you have an issue with your registry and you should search for help in specialized web pages. [external link: a possible solution].

    6. Now your file is ready to work!
      You can make a shortcut of it in your desktop and set an icon for the shortcut, the obvious choice would be the Wow icon that you can find in your World of Warcraft directory. [external link: changing the icon]

    Note: You can edit the code of the bat fastly right-clicking the file and selecting edit, then the .bat will open with your note editor and when you save the changes it will remain as .bat.


    Maybe something like this could be added to the addon description, it could be useful.

    I'm sorry for the language mistakes that maybe I made, I'm still learning english, since it's not my native language =)

    Thats an awesome post Highray! alternatively you can make a blank creaturecache.wdb (make a empty txt and rename it to creaturecache.wdb and put it in your cache/wdb/enUS/ folder) and then make it read only, then your game can never save your creaturecache when you close WoW, only downside to this method is that apperently every time WoW patches it deletes your cache folder completely sooooo you have to remake it... less work in the short run that Highray's suggestion, but in the long run Highray's is probably less work =]

  • #2026

    That's a great idea, thanks for share it. You could just have that empty creaturecache respalded in the Wow folder then when a patch delete it you just have to copy it again.

    Wow, too bad this can't be stickied.


    I do have an issue though, I can get this to work with WoW.exe and WoW-64.exe with no problems with this format:

    erase Cache\WDB\enUS\creaturecache.wdb
    start WoW-64.exe


    But not with the launcher, when I try the launcher with this format:

    erase Cache\WDB\enUS\creaturecache.wdb
    start "World of Warcraft Launcher.exe"

    MSDos just opens up, and stays open with the wow location address.

    When I use this format:

    erase Cache\WDB\enUS\creaturecache.wdb
    start"" "World of Warcraft Launcher.exe"

    MS Dos opens and closes really fast, but never accesses the wow launcher




    Found the problem, where I added the "" marks after the start command just needed a space
