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 have noted a similar behaviour. I now have deleted the creaturecache file *twice*, but it still lists a large number of rares as cached although I definitely did not get any alarms and have not even *been* in those zones. It puzzles me greatly. I will uninstall and reinstall this addon and see if that helps.

    Sometimes _npcscan will find something when I'm on a flightpath, which is fine - I just don't know where to go look when I've landed. A spot on the minimap and/or some coordinates of where said mob was last seen would be really useful.

    Search for and install the Npcscan Overlay addon. It has the option called, "Show 100 yard ring for approximate detection range (on the main world map or minimap)"

    Hi, does teh Mysterious Camel figurine also come under teh creaturecache or does it come under one of the others? I am asking this because i had it go off once in almost a year, i have cleared the creaturecache file, yet it has never ever gone off since, and that time another player had got to it before me.

    I am on practically an empty server, i have spent hrs just flying round very low, but now i am beginning to wonder if this item exists anymore or if npc scan detects it (i know that /tar macro no longer works) and that npc scan is supposed to detect but not target it anymore. Just wondering if blizard have changed that so it can no lomnger be detected by npc scan? Either that or the server i am on has it continously bugged and it never spawns up.

    i have tried like 3 times to clear my catch and it was working until yesterday now loque and king krush wont clear : ((

    I actually like the NPCScan alert sounds :) Can I download them anywhere as a .wmv or something? :)

  • #1575
    how do you clear the cache on a mac?

    World of Warcraft\Cache\WDB\enUS\creaturecache.wdb

    For most people World of Warcraft will be in their Applications directory, although you can put it anywhere. And if you're a non-English or non-US player, the "enUS" directory will be called something different for you.

    You can also just use Spotlight to find creaturecache.wdb, which will take you right to the directory. Then delete that file.

    Is there any way to turn auto cache off? There are rare spawns I am looking for and I have to clear the cache everyday. This is getting a bit annoying.
  • #1573
    I'm not the author but had to comment -
    I think you misunderstand how the addon works... The game populates the cache, and the addon checks the cache for any of the rares that have just been added. If the game didn't cache, the addon wouldn't work.
  • #1571
    few suggestions:
    “/targetexact …”
    -reset addon option to restore addon to default setting (incase user deleted mobs)
    -dont look for npc while on flight path
  • #1570
    How do I get the npc id number does the addon do this

    I am wanting to create a rares list of the uncommon rares sometimes I can not get the id number from some of the websites

    Would like to do it while in game
  • #1574
    I don't know if you have tried, but I just use wowhead.
    Search for the NPC, and look at the /npc= number in the URL.
