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 was able to experiment a bit and it does look like I should be able to display an alert when events like those rares are displayed on your map.  Keep in mind that due to phasing it will only trigger if it is active in your phase. 

  • #3243

    Yeah the rares for hellbane that are up are shown with a gray symbol on the map of the whole tanaan jungle. It would be really nice if you could fix that. And if you fix it then do something where it only gives alerts if you haven't killed them today.

  • #3236

    so im not getting any rare locations for the jungle. what am i doing wrong lol ?

  • #3237

    On the Overlay?  If so, it's because I haven’t had a chance to update the path list all the new mob yet.  It’s a manual process so it takes a bit of time to complete. I'm hoping to have it complete in a few days.

  • #3238

    dude you're awesome 

  • #3233

    For some reason, the npc scan is not alerting at all when a rare mob is up. No screen flashing, no sound, no animated trageting icon, nothing. Is this due to the changes to the game or have something to do with the computer I use? I play on a Macbook pro and am using the current version of the add-on.

  • #3234

    Where are the mobs that are not triggering?  If they are mobs in pre-Mop zones, the addon does not automatically trigger for them any more, due to changes made by Blizz when WoD.  If they are mobs in MoP/WoD zones check to see if the Vignette alerts are enabled in the settings.

  • #3242

    yeah it would be nice for ALL Rare's in the game to be Vignette and trigger the addon :)

    For Azeroth !

  • #3235

    Ah. I wondered if that might be a problem. I rely on npc scan when hunting rare pets in pre-MoP zones with my hunter. Do you know of any way to fix the problem?

  • #3232

    Ive been having framerate issues for several days whenever I go into a building or cave, one example is the Drag in Ogri. Anyway after much searching and testing this addon may be the cause, Ive been using NPC scan for a very long time so I have no idea whats causing my framerates to drop from over 100fps to 13fps when I enter the drag. (I have found this spot to be the best test so far ) After disabling NPC scan my framerates returned to normal. I have not checked to see if if Overlay might be the culprit and I did disable both NPC scan and NPC scan overlay at the same time. All I know for certian at this time is that with these 2 addons enabled my framerates drop to almost unplayable. There doesnt seem to be any issues at all if I am in the open world unless I get close to a hill or land of some kind. I have no idea how this addon is effecting my graphics, my machine is custom built with good hardware. All my drivers are good to go, so im stumped as to why this started. For now im going to turn off NPC scan until I can find an answer.

    After further testing, it appears that NPC scan overlay is the cause of my framerate issue. Framerate without Overlay enabled 105fpsFramerate with Overlay enabled, 13fps
    NPC scan without overlay doesnt appear to affecting framerates at all wether its enabled or disabled. I hope I can fix this in settings or a workaround since I rely on overlay alot when hunting rares and Spirit beast on my hunter.

    Ive narrowed down the framerate issue even more. When using NPCscan overlay If I uncheck the Minipap option I can actually see my framerates return to normal instantly.There isnt an open thread for NPCscan overlay but if anyone runs into serious jitters or framerate issues you can simply try and uncheck the Minimap option in overlay to workaround the problem. In my case I can 100% confirm this to work. It does not however help me figure out why it just started happening recently. Ive made no other changes with any of the game settings or with any addons. I first noticed these issues following a small blizzard update with the launcher or some files, im not certian what those were.

    For some reason I can't click the X anymore on the alert image that pops up when mousing over a rare.

    I try and click it, but it only selects the mob, it doesn't remove the alert.  In order to have it go away I need to reload ui.  Any idea what might be causing this?  Am using the version.

  • #3229

    i guess you are using ELVUI skin alpha release ?!

    Switch back to release version

  • #3231

    I have the release version (8.10) and it still doesn't work :(

  • #3227

    I tried adding a custom NPC for a battle pet but couldn't get it to alarm. Is that functionality not added?
