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 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.

“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.

    I keep getting a warning when starting wow that several mobs are already cached yet I have deleted the cache file folder several times before starting and the message still appears.  What's goin on?  Is there more than one place that wow keeps its cache now?  I'm in Win 7 x64

    There is a Rare in Howling Fjord. King Ping is it's name. I have seen him south of Kamagua, where you do the daily for the tuskarr.

    I <3 this addon. Thank you so much!

  • #1632

    I find a Collection Bot,

    easy to use.I appreciate all the hard work you've put into it.

  • #1631


    some really odd thing happened recently. While I use NPC and/or NPC_overlay the game doesn't recognise my keyboardpresses. Not even "ESC"! The only recent non-usual thing is that I went to  the new "Fair" and that I bought the charger-mount. Please help, I really rely on this addon.

    Kind regards

    Re: _NPCScan cache

    so what do you do if your cache folder doesnt reapear, but you still have most rares in cache and cant clear it because the folder isnt there.

    it worked fine for me a couple of times, but now the folder just isnt there anymore. I tried deleting npcscan and reinstalling it but it didnt work

  • #1634

    I had some issues with cache and wtf folders and found that my main live folder had been copied and assigned to the C:\users\public\games directory. I still have the original in the old location but the game runs from the new location while the original has no purpose (I'll delete it someday but am not worried at this point). You might want to run a search and see if you have a secondary location also. It sounds weird but it happened.  Foot in mouth

  • #1628

    Sounds like you have some other issue going on.  When you are not in game and delete your Cache folder in your Wow directory.  Once you start Wow again, the game regenerates the folder automatically.  Not really sure what else to tell you.  My Cache folder always regenerates.

  • #1626

    I just wanted to thank saiket for this great addon.  I have been using it a long time, and as a Hunter have found many rares using it.

    In regards to people posting about having issues with npcscan, I would like to offer my advice here.

    -Make sure "every" time before you start Wow, you clear your Cache.  I delete the whole folder, just to be safe.  Get in a habit of deleting the Cache folder before you start Wow.  If you are already in the game, you can't tab out and delete this folder.  You must do it before you start wow, or after you completely exit the game.

    -If you are say, sitting in Stormwind and someone calls out a Hunter pet that you are tracking in npcscan, "it will cache that pet in npcscan".  Even if you call out one of your own pets that you might be tracking still, it will also cache it.  So you must be aware of that, and do as stated above.

    -npcscan is not just for rare Hunter pets only.  You can track any npc.

    -to add a npc to search for "if it is not already loaded in" do the following.  Type /npcscan in chat.  This will take you to npcscan options.  Here you will see the list of npc's you are tracking.  To add a new one... you need to know the "name", "npc id" and "world".  This is all provided on wowhead.  Go to wowhead and find the npc's name and its location.  The npc id, is in your address bar "http://www...." look for the 5 or 6 digit number.  Once you have all 3 of those things input them into npcscan and click the + symbol.  Now that npc is added into your list and will be searched for.  Anything in that list that has an "X" beside it means it has been cached by npcscan already.

    -a good tip that I do.  I have a keybind bound to a macro that is as follows.  /npcscan cache This will tell you if anything in your list is already cached or not.  Its a quick way to tell instead of going into the npcscan options and looking for the X next to a npc's name.  So before you set out to find a npc, use that handy little macro to make sure nothing is cached.  If it is, exit Wow and delete your cache folder.

    I use npcscan daily all the time, as long as you follow what I have provided you will have no issues at all with this addon.  It works perfectly, 100%.  You just have to know how to use it.  I hope this helps anyone who needed information.

    I would like to ask the author if he might consider a few things in a future release.  Would it be possible to and an option for your overlay feature to be able to not track a certain mob in a zone you are in without having to delete it from the list?  I find myself sometimes with 4 mobs being tracked in a zone and some of the overlay's cross each other and I can't see it.  The colored paths get covered up by each other.

    Also to do with the overlay.  Would it be possible to add a sort of outline to the colored overlay's?  In some zones its hard to see the overlay color.  I was thinking along the lines of a white outline to give it some contrast.

    I too have had lots of issues even after deleting my folder many times.. I cant stand next to a mob and the now the NPCSCAN wont even go off. please tell me hoe to fix. this was the BEST add for hunters but now its brokenFrown

  • #1623

    Two things I'd like to see added.

    One, let me call up the button of the last found rare. More than once I've mis-clicked and closed the notification. Then had to spend time trying to acquire the target again. I just want a ay (maybe a simple /slash command) to bring the button back for whatever was found last, so I can easily target it. Edit: Just found the keybinding to do exactly this, so this request can be completely disregarded (end edit).

    Two, check if the rare is dead. NPCScan already checks for zones for tameables, I'd like a similar warning for finding rare corpses.

    I'm not sure if either is technically feasible, though.

    amazing... i read like 5 posts and none of them seem to know how to clear cache even though its explained CLEARLY in the info. people saying it doesnt work, read harder and fail less. LOG OUT OF WOW BEFORE DELETING YOUR CACHE, this mod works perfectly for me, as specified.


    it also states in game that IT WILL PUT HUNTER PETS IN YOUR CACHE IF THEY ARE RARE MOBS this is why people are getting mobs you havnt seen cached.


    i swear, reading is effing hard now

  • #1630

    I really get irked when people ASSUME that no one read how to "clear the cache". Im one of those that has read it.. reread it... and read it yet again and STILL get the same message when logging in that I need to clear my cache.

    Dont assume just because someone says they are still having problems that they "didn't read".

    Makes you look like the ass you are.

  • #1621

    Maybe some one already wrote it before but i create a batch file for clearing the cache.

    For Win XP:

    Create a new document file and copy-paste those lines in the document

    cd C:\Program Files\World of Warcraft\Cache\WDB\enUS
    del creaturecache.wdb

    Save the file on your desktop with any name but replace the ".txt" extension by ".bat"

    Ex: NPC_ClrCache.bat

    Double-click the file everytimes you launch WoW.

    Note: To test the batch file, double-click it with the cache folder window open.  You'll see the file disapear.

  • #1670

    You gave a very helpful response. It's so difficult to try and give specifics that work for the majority... I'd add three things:

    1) Check and see where YOUR creaturecache.wdb is. You may need to modify the directory structure given in the above example.

    2.) On most modern Windows machines 'out of the box', you will have to make sure the extensions are not hidden. If they are, the file type will not change when you add a .bat to the file name (and you won't see the '.txt' mentioned in the example.)

    3.) If you are not comfortable with doing the above, don't mess with it. Get a friend who does these minorly-geeky-things to set you up.
