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.

    If already cached, then it is too late. The only reason we got the signal in the first place was when the addon noticed the rare was not cached and then just switched to be cached. Impossible to get another signal on something that is already cached and you are checking if it is cached.

    The silverdragon addon is an alternative if you want rares on target mouseover for repeated warnings. But you still miss a lot flying over them because your mouse is in the wrong place.

    Re: _NPCScan issue

    For some reason NPC scan isnt working at all, even after clearing the cache. I had a rare spawn right in front of me and the NPC scan didnt do anything. Is anyone else having this issue?

  • #1888

    I got the same problem as Angelus, NPC-scan not working for me now, I've cleared cache. Can stand infront of rares without anything happening.

  • #1891

    No, im running it "vanilla". Been using NPC Scan for over a year, first time im encountering an issue where its not working.

  • #1889

    did you download the npc overlay that someone posted in the comments section of the overlay section?

  • #1882

    hi, i don't see rare's locations on the map it's normal ? thx for the answer :)


  • #1884

    This has been adressed further down in older comments, rough estimate locations have been added to a specific users copy of the addon, and he/she has shared it so that other people can use it, for now.

  • #1881

    I was wondering if it would be possible to add some of the rare wild pets to NPC Scan? Like the Minfernal, Scourged Whelpling, Dancing Water Skimmer, Molten Hatchling, Tiny Twister just to name a few. It would make hunting them down soo much easier!


  • #1877

    I've deleted the cache folder multiple times and have tried the procedure Omrakos outlines in the thread you linked (a WoW folder wasn't located there), but still cannot clear my cache. What could be wrong or what else can I do?

  • #1879

    all you need to do is completely close wow then under your start menu go to find file and type in creature. it will find the creaturecache and you right click on it and delete. then re open wow.

  • #1883

    thats weird because i only ever have to delete the creaturecache

    Almost, I had to Start>Search>No Results found at first>click Computer icon>Delete BOTH creature files it found and it finally worked!

    Deleting the entire Cache folder didn't work, but this did ... hmmm

    Adding the ability to detect objects in another cache folder would be great, considering the BOA items in MOP these days.  Just a thought.  Not sure if it's possible.

    regarding pandarian rares

     im wondering have you updated for pandaria at all saiket? its not showing any of them on the search /cache list and its showing no overlays for them even though i am in the area it travels. if you have done this whats wrong with mine that it wont show the overlay? if you havent added this then when do you think you will? im a hunter and would like to tame the rares in pandaria and that is difficult without an overlay to follow to find the tracks.
