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.

    The answer is in the desctiption.


    The only problem mobs for _NPCScan are tamable beasts.  Even when 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.

    Could you happen to have another toon (hunter) that has already tamed them?

    automatic cache clearing

    Go to your WoW installation with the WoW.exe, create new text file, rename to WoW.bat add the 2 lines below and save, change your desktop shortcut to start the new wow.bat file.

    del /S "creaturecache.wdb"
    start "" "Wow.exe"

    this will automatically clear your creature cache and start up the game.  if you are using the 64-bit version of the game, change WoW.exe to WoW-64.exe

    this is for windows

    Something must be missing from these instructions, because the .bat file is just a text file, it doesn't change to a script file. Also when trying to change my desktop shortcut to wow.bat, it tells me that its invalid.

    You have to be able to see file extensions, otherwise you are changing, for example Wow.txt for Wow.bat.txt (which is a txt file named Wow.bat).

    You can see the file extensions by changing the options in "folder options".

    Note: If you changed the extension to .bat and you need to edit the commands instead changing back to .txt you can simply right click the file and select "edit".


    Explanation of the commands given by Blodaks

    del /S "creaturecache.wdb"
    start "" "Wow.exe"

    del       Delete one or more files. It is the same than "erase".

    /S         Delete files with the specified names from all subdirectories. This means that it will search in all subdirectories files with the given name.

    "creaturecache.wdb"   The name that we are giving to "del" to delete, is the file name where Wow saves the cache of NPCs. The quotes are necessary if there are spaces in the file name, considering that this is not the case we can omit it.

    start    start a program in a new window.

    "" "Wow.exe"  The program that we are giving to "start" to execute, "Wow.exe" is the name to run Wow directly, you can put "World of Warcraft Launcher.exe" if you want to run the launcher instead (if your executable files have different name put the one that you want correctly). Some MS-DOS's "start" command may interpret the quoted program name as the window's title; then he put an empty quotation "" before "Wow.exe" for 'cheat' it.

    Anyway you can be more specific in the del/erase line, that way you save a few seconds, I will write it in other post to don't do this too long.

    you left the .txt at the end, the txt needs to be changed to bat.  if you cannot see the .txt file extension, i suggest turning it on in folder options.which you should be able to find in the control panel under the view tab.

    OK, I'll try this after work, and I'll reply back with confirmation, I really appreciate you guys taking the time to respond:)Cool



    Instead of using wow.exe or wow-64.exe, can you use the

    World of Warcraft Launcher.exe?

  • #2015

    Wow this would be incredible, can someone confirm this?

  • #2011

    An update,  if possible, it will be greatly apreciated, tks

  • #2010

    Now instead of just not working; the Glorious achievement npcs have been disabled. :|

  • #2008

    Doesn't work. Not updated for the latest patch.

  • #2007

    For awhile this worked great; but recently it has stopped working. I've cleared my cache multiple times and tried re-installing it. I actually loved this addon so I could camp Scritch without being at the laptop but not sure what to do now. Even the addons page before you enter WoW says NPCScan is out of date. I load it anyways but still doesn't work. I've tried disabling all my addons and that doesn't work. 

  • #2009
    For everyone who's going to complain and point out that this addon doesn't work right now it's because Blizzard recently did an update patch, which most of you should have noticed by now, and the Addon Manager hasn't updated this addon yet. Be patient. Take a deep breath. It will be back.
