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.


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.

    is there any way to add lower level rares? im in ashenvale as a 22 and came across 2 rares by chance.  i looked at a website and found at ashenvale has close to 10 rares. it would have been great to know these rares existed and have it show on my map so i know where to look for them.


  • #1691

    go to wowhead and look at any npc(you have to view its personal page)  the number at the end of the url is that rares npc id enter that #, the name and continent in the _npcscan creature listing save it with the little tab off to the right on its own and then it will start to show up with a cleared cache or the first time you happen to see it.

  • #1683

    Feature Request 1:

    Can we get the ability on a per creature basis to disable the alert for creatures below the character's "green" level? This would be extremely useful for people like me, who add in all the rares throughout azeroth so that when leveling up an alt, you can find the rares near your alt to kill them for the generous amount of XP you get from killing an of level rare. I would in-vision the achievement rares to bypass this restriction as well as having the ability on a per mob basis to enable/disable this feature.


    Feature Request 2:

    Have the ability to toggle a global config so that all the mobs and settings, and alert window position are the same on all toons.


    Thanks for the time and consideration and of course for the excellent addon. One of the best ever made.

  • #1682

    New borders arent so nice :< any way to change em back ?

  • #1681

    How can I reset the addon? Ive deleted some creatures by mistake and dont know how to put them on the list again.. so Im not currently abble to find them ):

    Dunno what to do, Ive already tried uninstaling the addon and erasing the folder and etc... but it didnt work. What should I do?

  • #1692
    as i said above, will also replace deleted ones  go to wowhead and look at any npc(you have to view its personal page)  the number at the end of the url is that rares npc id enter that #, the name and continent in the _npcscan creature listing save it with the little tab off to the right on its own and then it will start to show up with a cleared cache or the first time you happen to see it.
  • #1678

    I just want some confirmation on this: if you're tabbed out of WoW (WoW is in the background) and even if you have background sound enabled (meaning you can hear music, ambience etc. while in background), can you hear NPCScan go off?  If not, will it immediately go off when you put it back in the foreground regardless of whether or not the rare has left the vicinity?

  • #1679

    And to add onto this: if an NPC appears while you are tabbed out, does it get added to your cache even if it leaves the vicinity by the time you put WoW back into the foreground?

  • #1693

    as to the sound part i cant answer but would assume yes just as the normal ui entering combat sound does, for the other 2 ... 1) no the flash and npc photo will not go off until you have foregrounded the screen ive had this happen plenty of times specially on flightpaths tab back in and BLAM flash pop and aww crap time to turn around 2)  yes it will get cached

  • #1674

    I'm just chiming in to also complain about the cache problem. I'm almost always greeted (upon logging in) with a cheerful message about how all sorts of cretures are already cached despite deleting the damn cache files a million times. Either there are many other areas where Blizzard is caching this or your addon is also saving or mirroring the cache file somewhere.

    Those might be tamable pets (or mount(s) that someone already got) that you probably got close to in a city somewhere (in other words, the addon picked them up from another hunter who had tamed them and you probably walked right past them at the bank or something).

    Read the addon description above for some advice on how you might be able to handle this issue.

    Re: _NPCScan clearing cache

    YOU gotta put a button insidee thsi add \-on to clear the cache. or, abutton  "UNCHECK" THE ONES PREVIEOUSLY DISCOVERED. I really like this add-on, but having to clear the cache is a royal pain.

  • #1707

    The cache is a Blizzard file and is protected so that it can only be cleared when the game is not running. The addon writer can do nothing to fix this issue.

  • #1671

    I'd like to add that you don't HAVE to delete the "creaturecache.wdb" file each time before starting the game if you simply change the file attribute to "read only" by right-clicking the file and then clicking "Properties" and placing a tick mark in the "Read-Only" box.  Once done, every time you exit the game, any NPCs that have been found are discarded because nothing can be written to the file.  You will want to move your toon to a spot where there are no NPC hits first, exit the game, delete the file one last time, fire up the game to cause a clean, unmodified file to be created, exit the game again, change the file attribute to "read-only", then you are done. You will always have a clean, unmodified file when you start your gaming session.

  • #1684

    did this, works great, only problem is if you have an updater problem, make sure you go and uncheck this.  after updater is successfull, it will make you a fresh brand new clean cache file which you can make read only again.
