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.

    Use Curse's tool to uninstall the addon and delete any NPCScan-related files in your WTF folder and reinstall.  That's just my generic-process answer.  Don't hold me to it.  :P

  • #1757

    no luck  :(

  • #1740

    I've been camping TLPD lately and I've seen a lot of Vyragosa. I noticed recently, however, that NPCScan hasn't been announcing Vyragosa's spawn even though I clear my cache prior to every login. I check the logs to verify Vyragosa is not cached, and I often come back to my computer to find that no message has shown up, but she is cached in the logs anyhow. 

    I also recently had a friend looking for Vyragosa and killed her within range of me. NPCScan did not go off neither for her corpse nor for her while alive. She did, however, show up directly after cached in the logs. Note: I had checked my logs for her cache about 10 minutes prior to this kill and she was not at this point.

  • #1744

    If uninstalling then reinstalling somehow didn't work the only thing I can think of is to manually add all the mobs back. You can find their ID's on WoWHead (see link in the add on description above).

  • #1739

    Hi folks,

    I'm using multiple accounts to camp for TLPD and Aeonaxx, but i keep having an issue with the addon.

    While at Storm Peaks, if the addon is triggered by (most likely) Vyragosa on one of the accounts, wierd thing is that on the other accounts it will turn as if they had spotted her too. And this happens whether i use the same wow folder for say, 2 accounts, or if i use different wow folders on different hard drives! Just now it happened again, 2 accounts on same wow folder, one found Vyragosa dead, and the other can no longer track her. And this persists even after clearing all Cache folders everywhere.. I log back on to the game after deleting cache, and one account is cleared and the other can't track Vyragosa anymore

    Anyone with the same issue? And is there any other folder we may need to delete for it to fully clear it's cache?

  • #1745

    I have nothing useful to say other than I find this very odd. I use 2 accounts and they both have different mobs cached on NPCScan. This just happened by itself, I didn't go out of my way to create new folders or anything so I'm rather stumped as to why yours is working differently.

  • #1754

    Using multiple accounts I just found Vyragosa on a child account and flew my main account to the spot to kill her.  Only the child account's scanner alerted.  I would have expected my main account to alert as soon as he got in range of her.  Something's not right.

  • #1738

    Is there a reason why NPCScan doesnt alert you when you find Gondria or Skoll in Northrend?

  • #1735


    Starting to camp for TLPD, I have run into the following problem:

    I camp while doing other things (of course), but those things mainly involve use of the computer.
    I have enabled sounds in background and can clearly hear the music from The Storm Peaks while doing other things.

    I was watching a youtube video in full screen (maybe this is the cause), and after watching, I tabbed back into the game to comfort my mind. As soon as I got tabbed in, NPCscan went off.
    It had found vyragosa, but not at the moment of tabbing in It was a good 10 minutes ago.

    I did not get a sound while alt-tabbed. I can understand this being because of youtube on fullscreen, but I'm worried that any moment that you're alt-tabbed will delay the caching in WoW, and therefore the alerts.

    Could you please clarify?

  • #1736

    Hi Pathemeous I had the same problem as you did at one point too. The way I fixed it was to use Full screen in windowed mode. Normal Full screen seemed to cause the delay your talking about. Hope my info helps you.

  • #1746

    Putridus the Ancient was scanned when camping TLPD (no idea how, but the guy is big so I guess its caching range is big as well?) This was while I had WoW minimized in Windows (Fullscreen) mode. 


    therefore, above is confirmed.

  • #1732

    Dose this not work for mysterious camel figurines anymore!?!


  • #1730

    Annoying, but my NPC scan found the corpse of the Time Lost Proto Drake and now it's counting it as though I already killed it.

  • #1733

    @ haiminh, NPC scan will trigger when ever the npc is found ( dead or alive.) there is cache issues but its not that bad considering the addon is not counting it as kills.

    @ nija, you can still find the mysterious camel figurines, it just takes a lot of time to find it and have npc scan trigger. It took me almost 12 hours of flying around till it triggered and I found it.
