About _NPCScan

If you care at all about my wishes, you won't download this AddOn from SolidIce: They are leeching it from the site I actually choose to put it on.

_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.
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.

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.



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.  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.  That page's URL will look like

32500 is Dirkee's NPC ID.

    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.

  • #1625

    May I suggest rewriting the code as;
    del Cache\WDB\enUS\creaturecache.wdb
    START Launcher.exe

    This WILL require the BAT file to be placed in your WoW installation folder, but will also fix any issues with WoW stored on other hard drives or 64-bit (as most systems are these days).

    Create a shortcut on your desktop, and when it runs the program will delete the cache and also run the launcher for you.

  • #1619

    I have a suggestion to this Addon.

    I think that you shall add a button ingame that automatic clears your cache, that way we dont need to close down wow and manually clear cache and save alot of time.


  • #1617

    I have cleared the cache like 5 times today and it still tells me every rare creature I've seen since install is cached. I deleted the right creaturecache file and all. Still wont reset Cache. I now have almost every rare creature cached, does this mean it wont work at all on those creatures, now rendering this app useless?


  • #1616

    I have 2 account and usually camp on 1 account and do other stuff on another, can you possibly make it so that NPCScan annouce in party that a Rare is found including the time or something similar to that effect. TY

    Does NPCScan communicate with others? because it will say i have cached rares that i now i havnt. JW if its a bug or if it communicates with others. TY

  • #1614
    It's time !

    ... for a new version. NPCscan slowly and surely is *** me off.


    The reasons:

    - no way to set or unset single mobs

    - today: I have NOT deleted the cache, I have NOT marked: show all pathes, and what the tools is doing: showintg me ALL pathes again.

    I think, NPSscan (and overlay) needs a kind of setup with more functions. Functions, which can be manupilated by the users.

  • #1613

    This addon is broken.

  • #1612

    I have used npcscan with good results, but lately it does not give ant warning nor does it show the "cached" rares that are logged. I have also experienced some cached creatures that do not get removed when I delete out the cache from my system.

    Hope you can explain the problem or get it fixed, have loved this add-on.

  • #1611

    Does not work! As other have said it will cache rares that I have NEVER come across and at the same time I can be standing in front of a rare and no warning goes off.
