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.

    I really love this addon. I do have a suggestion though, can you add a setting to turn off caching?
  • #1041
    The game caches mobs whether _NPCScan is on or not, so there's no way to disable it.
  • #1035
    My problem is the following.
    I updated this very useful addon with curseclient after 4.0 has came to live servers.

    Now, I found a rare mob (only because the mob were nicer than the others and I flew near him and saw it's Old Crystalbark)and the addon weren't doing anything.
    I deleted the chace folder, it was a missing rare etc.
    After it my mate found an another, but the addon were still silent.

    Any advice?
  • #1036
    Have you updated since then? I didn't release the Cataclysm version until just after the US servers came online, so you might have grabbed version if you updated earlier than that.

    If you do have version 4.0.0.x already, it's probably settings related. I haven't seen Old Crystalbark in a while, but I did test scanning on a random Borean Tundra mob and it was detected fine with version Do you have the "Frostbitten" tab's checkbox enabled in your "/scan" settings? Another possibility is this is the second time you've killed Crystalbark, and you have the "Search for completed Achievement NPCs" option enabled; Try turning that off if this is the case.

    I'm not sure about your why your friend would have similar trouble, but it could be one of the above or a cache issue if it was a tamable mob.
  • #1040
    My problem is solved.
    The main issue was that my curseclient didn't update the entire folder so I had a few remaining file from 3.3.5.
    So I deleted my _NPCScan folder and updated the newest release again.
    And voila, it's working again. :)

    I got this error on logging in. As seen by BugGrabber, English client.

  • #1059
    What does the cross means lol anyone can tell me
  • #1033
    WoW 4.0.1 isn't compatible with older versions of _NPCScan (you have still), so you'll need to upgrade to the latest version.
  • #1029
    I spent hours trying to find NPC id's and couldn't find: Example, Spirit Beast, Loque'nahak 76 Rare Elite Sholazar Basin . Its not in your current database.

    Is there a way to ADD without a NPC ID to _NPCScan? This is holding me up to add.

    #2: Do you have a current list of NPC ID's that you can make available to download? This would greatly simplify things to add.

  • #1031
    Easy peasy. Just search for the mob by name on Wowhead. Once you're on the mob's individual page, look at the number after the = sign in the URL. That's the NPC id. Here's an example for Loque'nahak. I went to and did a search for Loq. Once I clicked on the NPC page, this is the URL I got: The NPC id is 32517. That's what you put in the NPC ID field. Hope this helps.
  • #1032
    Thank you.

    Wouldn't it be great if there was a downloadable list with all the NPC id codes
  • #1023
    I am currently using the latest version of NPCscan ( and there seems to be a problem that starts to happen after patch. As you may know, hunters have an improvement on their stable slot mechanics, in that they can have 4 "active" pets and 20 "inactive" pets at level 80, tucked inside their stables. Now, even after clearing the cache before logging in, NPCscan seems to auto-detect whatever rares I have inside my "inactive" stable slot as soon as I log into the game (and haven't visited the stables). Of course, if I happen to log in on the zone where the rare is supposed to spawn, the warning siren will turn on. This happens even though I don't have any rares on my "active" pet slots.
  • #1025
    I can confirm this as of right now. I just noticed this on my server as of the new patch. I cleared cache and was sitting in Zul'Drak. As soon as I log in the sound goes off that Gondria is up, now I am sitting near one of the spots so I look around. It was then that I noticed that all of the spirit pets I have in the stables are listed. Was very odd to say the least.
  • #1024
    I hadn't heard about that change, so I made a premade hunter on the beta to test this. Sadly the beta is down for now so I can't log in. :(

    I think I might be able to stop bogus "Found" messages from showing up in this case, but I'm not sure. Also, I think this is going to make it impossible for hunters to scan for tamable mobs to kill once they've got one tamed.

    I'll try working this out once the beta servers come back up; Hopefully it won't take too long.
  • #1026
    Version will print a message listing cached pets from your stables on login instead of showing a found alert. It should also prevent bogus found alerts for pets you have with you (I'm not sure if this used to happen before or not).

    You can disable the message by turning off the "Print cache reminders..." option.
