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.

    Re: _NPCScan: screen flash, sound and 3d model not showing up

    Guys anyone run into this?

    If I pass by a rare it goes directly to cache do not pass go do not collect 200$ ... doesn't matter which zone.  Never alerts, flashes the screen, sound nothing ... but, like I say the odd thing is, I check my empty cache (yes after deleting it) zip ... straight to cache. (yup these rares are alive).  It was working though and yes went through the regular steps of removing adding it ... killing wtf and cache.

    Appreciate the add on though it's a tremendous utility.


  • #1965

    Same problem here.

    Already cleaned cache folder (the game shows that no npc is already cached), but when I find a rare npc, it just marks on the addon menu and doesn't sound that alert (nor shows the npc model in the screen).

  • #1969

    Did you already try deleting the _NPCScan folder from your World of Warcraft\Interface\AddOns folder and reinstalling the addon?

    Of coarse have wow closed out while your doing this.

    Delete Creature cache and start WoW :D

    Wrote a batch file that deletes the Creature cache then starts up WoW. Thanks for the awesome Addon :D  Cool

    This is just an example of how I did it with quick explanation.

    Create a new Notepad,

    Enter in these lines exactly and change the cd directories to fit your creature cache file and wow.exe locations.

    @echo off
    Rem Creaturecache
    cd C:\Users\YOUR USER NAME\World of Warcraft\Cache\WDB\enUS
    del creaturecache.wdb
    Rem WoW
    cd C:\Users\YOUR USER NAME\World of Warcraft
    start World_of_Warcraft_Launcher.exe

    Save As, whatever you want the file name to be.bat to your desktop.

    Make sure you save as .bat and not a .txt file or else it wont work.

    Now Open the .bat file and voilà, Creature Cache is reset and wow starts up.

    you are patially right but a lot of people install there wow not in user folder so something like this

    C:\Program Files (x86)\World of Warcraft\Cache\WDB\enUS

    Also I noticed all that pops up is another CMD window.

    I posted for that file location as well. please read further posts.

    Plus I also mentioned to modify the cd directories to match your own personal location.

    Not working I get "cannot find World_of_Warcraft_Launcher.exe"

    Using Win7 64-bit

    @echo off
    Rem Creaturecache
    cd C:\Program Files (x86)\World of Warcraft\Cache\WDB\enUS
    del creaturecache.wdb
    Rem WoW
    cd C:\Program Files (x86)\World of Warcraft
    start World_of_Warcraft_Launcher.exe

    I actually figured that out but didn't feel like changing what I had already posted >.>

    Regardless, modify the syntax however you like, was just posting because I was feeling generous.
  • #1976
    Quote from SpykerX07 » There HAS to be underscores.

    Actually that is because you guys aren't using quotes to encapsulate the path, the command line will assume spaces are to separate arguments, but if you group them with a " around the path to the launcher it will run it without problems. It's more of a syntax issue than a limitation by the system. Just saying! ;)

    Besides this is only valid if you installed the game in the default location, in program files, otherwise if you run older OS or different OS this isn't always the case.

    Exactly what ryan92084 said,

    Go to your wow directory and rename World of Warcraft Launcher to World_of_Warcraft_Launcher. It will not run if you use spaces, There HAS to be underscores.

    You can also set the batch file to run wow directly instead of doing to launcher first. I just prefer to use the launcher first because I like to see new notes and  such.

     Depending on which OS you have. I havent tested on 32bit and 64bit, this is just what I'm assuming.

    EX: 64bit you want to use Wow-64.exe

    @echo off
    Rem Creaturecache
    cd C:\Users\YOUR USER NAME\World of Warcraft\Cache\WDB\enUS
    del creaturecache.wdb
    Rem WoW
    cd C:\Users\YOUR USER NAME\World of Warcraft
    start Wow-64.exe

    32bit you want to use Wow.exe

    @echo off
    Rem Creaturecache
    cd C:\Users\YOUR USER NAME\World of Warcraft\Cache\WDB\enUS
    del creaturecache.wdb
    Rem WoW
    cd C:\Users\YOUR USER NAME\World of Warcraft
    start Wow.exe

    Once again, Edit the cd directories that point to your wow folder.

    Also, if your running from c:\programs(x86) you might have to run the batch file as administrator.

    Heres what I did.

    Move the batch file to your wow directory, (the same folder that wow.exe is in).

    Now right click the batch file and Send to -> desktop (Create Shortcut). You should now have a shortcut on your desktop.

    Right click the one on your desktop, Go to properties, Shortcut tab at the top, Advanced..., Check the box Run as Administrator, Click OK, then OK.

    Then try to run it.


    You can always edit the old batch file by Right Clicking either the original Batch file or Shortcut Batch file and going to Edit in the dropdown.

    Re: _NPCScan 3D Model

    Is there a way to get rid of the spinning 3D model with the button?

  • #1966

    Is there a "/" command to get rid of it? The 3D model is the only thing I can't stand about this wonderful addon

  • #1958

    The addon is great, thank you.  As a future development, would it be possible to create a Tillers tracker, showing the locations on the maps as you find them, if you could put in the txt that pops up what they like/eat that would be fantastic Smile
