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.

    Great app BTW I used it alot WOTLK when I last played.

    I had a quick questions in regards to the changes. 1. Does NPC scan for like name plates etc or is the only way to find pre-vignette mobs is to use the macro key binding? and 2. what did they change that made this not possible?

    Can anybody tell me what "channel" NPCscan uses to print out the messages?  I'm looking to create a seperate chat tab, for NPCscan data only.

  • #3298

    Why do I still get sound alerts for Terrorfist, Doomroller, etc spawning when I have NPCScan set to mute? Hitting "Test Found Alert" confirms that there's no sound alert, but I still hear them when those mobs spawn.

  • #3311

    I had to turn off npcscan due to this. I can't take it anymore.

    Sad, been using this addon for so many years.

  • #3308

    Same problem as you are having, hitting test produces no sound, but the sound still plays.

    Hello SLOKnightfall ,

    Sorry if this has allready been suggested or asked for ....... , but i was wondering if there was a way you could add an  " Easy Add NPC to Custom mob List "  Button on the  Warning screen that pops up when you are near a rare ( or mouse over it for most Pre-Mop rare's ) , this would help greatly in adding those missing Rare's that are not Auto warned about when near them ( again mostly is a thing for Pre-Mop rare's since that API change from blizz  you mentioned -_-   ........ )  ,

    Tbh i'm not sure if this is even possible or you probably would have added this ages ago , but if you can it would be a big help since having to check wowhead and look for  Name / NPC id / ....  for each and every rare you encounter and adding them Manually in the list is a bit tedious  :p

    i await your reply ^^

    I can't get the map overlay to work unless I have "Always show all paths" selected.  I have Main World Map set to enabled.  Is there another option I'm missing that brings up map overlay and then causes each mob's map overlay to disappear as I find them?  Thanks!

    How can I get rid of the alert for "The Blood Moon". It's really annoying that it alerts of the blood moon from anywhere within Tanaan. I don't want to do the blood moon event, nor do I need the toy it drops anymore. Also I do alot of realm hopping for the Hellbane rares on 5 characters, so it gets really annoying to constantly get multiple alerts for the blood moon everytime i phase into a realm where it's up, or when it's up on my realm, or worse yet, up on both and get double alerts.

    I tried looking in Interface>_NPCScan, however the blood moon is not listed under hellbane nor junglestalker. So I am unable to tell it to stop alerting for it.

    I looked up on wowhead of the blood moon's ID, saw it's 91200, however i tried /npcscan remove 91200, and it can't find it, and I also tried /npcscan remove the blood moon and still nothing.

    Any help would be appreciated to get rid of this annoying alert. thanks.

    I'd also like to get rid of the Blood Moon alert.  I'd rather not modify the lua code as that will obviously get overwritten whenever I update the addon.

  • #3300

    Assuming you never want to see it again, in Vignette.lua go to line 94 ("if textureIndex == MAP_EVENT_ICON then") and put

    if name == "The Blood Moon" then return end

    on a new line directly beneath it (no external quotes, the ones around blood moon are fine). This will prevent _NPCScan from notifying you about the Blood Moon, but leave everything else intact.

    EDIT: lethalspoon has suggested an alternate version of this which will alert you to the Blood Moon unless you have the related toy. It's placed in the same location (and in place of) the above snippet.

    if (name == "The Blood Moon") and (PlayerHasToy(127666)) then
       return -- No need to ever kill this mob again

    Thank you for that info!  That alert was going off repeatedly was annoying.  Now we can farm those rares in peace.

  • #3297

    Same, would really like to get rid of the useless The Blood Moon spam, not to mention Veng/Terror/Doom and Deathtalon spam when you no longer care about that.

  • #3295

    I would also like to know this. Plus, I keep getting a similar alert for "Netherstorm Flag." I tried looking it up on Wowhead and all it tells me is that it's a spell related to a BG (probably EotS). What is it and how can I turn it off?

  • #3292

    So I'm having a slightly different problem...  Npcscan does not alert for mobs spawning in the area I am in until I attack them.  Then It alerts and the target button pops after the mob dies.  I have all filters active.  The Hellbane achievement alerts as it should no matter where I am in the zone.  I have uninstalled and reinstalled the add-on and no change (on all toons).  

    Any suggestions?

  • #3289

    What's a Vignettes mab compaired to other mobs and what rares do we have to worry about it not detecting?
    Just pre WOD rares only, or are there rare mods in WOD that this won't pick up?

    Thank you...
