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.

    No, its not a pain in the back side, its the only reason the mod is possible in the first place.

    WoW does not offer a direct way for an addon to continuously scan if a given mob is in the area on its own. The author found an ingenious trick where he could continually scan WoW's internal cache instead. The drawback is it only works once until you clear it.

    Instead of deleting the npccache.wdb each time .. just delete it once, create a empty file of the same filename & set it to read only.

    I've been doing this for months! You only need to delete it/unmark it as read only when there is a patch update.
  • #1535
    This is genius!!!
  • #1530
    i meant to say create a empty creaturecache.wdb and set it to read only.
  • #1533
    Still, as a hunter deleting or putting it to Read-only is not viable. The hunter pet pictures are stored there, so your pet selection bar is reset every time.
  • #1539
    Suggestion, clear the cache by deleting the file. Then summon the pets you want the pictures showing for and then mark the file read-only. :)
  • #1532
    Wow! Thank you so much for this! So simple, I'm surprised it never crossed my mind.
  • #1522
    Does anyone know what options to select to make NPC Scan alerts go through even if WoW is minimized? I have enabled "sound in background" but although I can hear the flapping of wings or game music, the alert sound for an NPC doesn't pop up unless I bring the full window up. And by then its dead usually. I just hate to miss the mobs if I'm looking something up...
  • #1523
    So wait. It DOESN'T do the sound if you're tabbed out? That could be a deal breaker here. Can anyone confirm or deny this?
  • #1537
    it DOES work when tabbed (ie on firefox looking stuff up). it does NOT work when minimized (actually downsized not running in the background).

    I know this is fixable because there is an addon that lets you hear BG and dungeon pops when minimized. I'd love to have that replicated for this addon as well.
  • #1524
    I just tested it. It is true
  • #1526
    I play wow in fullscreen(Windowed) and the sounds work when im tabbed out.
  • #1527
    its acutally, windowed(fullscreen). my bad
  • #1520
    For people tired of clearing the cache try the addon SilverDragon found on this site.
