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 don't get why you don't make it so that when you kill the NPC, it won't bring it up after that.  Instead, we have to go through our addon directories and find out which ones we've killed and which ones we haven't.  It gets extremely frustrating doing this..

  • #2051

    Any addon that searches for a specific type of creature/mob has to use the combat log to determine when it appears.  This is not the authors fault, its the way the game is made.  Blame Blizzard for making you have to clear the cache for addons like these to work properly, and thank the authors for making these addons in the first place.

  • #2052

    Nope, that is not the issue.

    It appears to me that the modification of the mod over time came to some dirty coding which introduced buggy behavior.

    The problem is that there is code monitoring the achievments which should be able to exclude at least the ones contained in achievments with 100% accuracy only when they have been killed.

    The problem with the code is that if a mob is in the cache, i.e. already seen it will due to some dirty coding not consider it in the scanning anymore. I have posted a patch in the _NPCScan.Overlay mod section, because it was with th eoverlay that I first found the problem, but the patch is actually in NPCScan.

    However the patch is not a solution but a workaround as it breaks the "Scan completed achievement NPCs" option due to the dirty coding.

    I hope this gets fixed sometime in a better manner.

    P.S.: Note that I do not want to blame the author for th edirty coding. Most people developping mods don't have the time to rewrite their code when it should be due to big modifications which may then lead to diry hacked code. This is a spare time occupation after all.

    Easy Cache Deletion

    I recommend creating a batch file (.bat) that automatically deletes the creature cache file. Just create a batch file with the text:

    del "C:\Program Files (x86)\World of Warcraft\Cache\WDB\enGB\creaturecache.wdb"

    You might need to change the directory path a bit. Put the file on your desktop, and when you double click it, the creature cache file is deleted :) Much faster and easier than manually finding it and deleting it everytime :)

    Thanks man, this makes it so much more painless, to just do this before starting up WoW :)

  • #2046

    Wieso muss man "Veraltete Addons laden" aktivieren damit NPC_Scan weiter funktioniert, wird das Addon nicht mehr aktualisiert?

  • #2045

    Please get this updated so it works for 5.1

  • #2047

    It works fine with 5.1. Just make sure you enable out of date addons. I've been using it without any problems.

  • #2050

    i have 5 outdated still. havent been able to isolate which one is causing random crashes. but it apears to be a combo. would love to have this updaed so those go away

    that's why its important to update even fi it would normally work fine. to verify this does not happen

    I have been playing without this mod since the big patch... waiting for it to be updated.

  • #2041
    Is there a way to get npcscan to show the colour marker it does on the world map and mini map for the npc you add as such
  • #2040

    Hi, I really like this mod you made cause make my rare mob hunting easier.

    But it make me really upset when it alarm and I can only see a dead corpse there.

    So can I turn the alarm off if the mob was already dead,

    or maybe you will add this function in the future please? :)

  • #2036

    About the popup image you get when you find a rare:

    It would be awesome if you could include information about whether you have killed the mob or not (for achievement). Just a small checkmark next to the name or something similar would be fine. NPCscan already tracks that info anyway, it's just hidden away under addon config settings (search dialog).

    Everytime I get the alert I have to go into addon settings for NPCscan, look at search dialog, look at the achievement tab (like "Glorious!") to see if I can just skip this rare mob or not.
