About _NPCScan

If you care at all about my wishes, you won't download this AddOn from SolidIce: They are leeching it from the site I actually choose to put it on.

_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.
V5.x Changes
  • Due to changes in how the addon stores data, some settings might get reset when updating.
  • The default alert is suppressed while on flight paths by default. If a mob is found, the whisper sound effect will play and the mob & location will be placed in the chat log. You can turn this off from the settings.
  • _NPCScan now includes all rare mobs in the game.
  • The "One of Many", "Timeless Champion" & "Champions of Lei Shen" Achievements have been added.
  • Rare Mobs and Tameable Mobs have their own tabs now.
  • Custom mobs have been added for the Ghostly Pandaren Fisherman & Craftsman.
  • Individual mobs can be removed from their tabs to stop tracking them.

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.



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.  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.  That page's URL will look like

32500 is Dirkee's NPC ID.

    I downloaded and installed the newest version and overlay, I can't find a cache folder anyplace and yet when I log in it tells me that all the NPCs are already in the cache and to clear the cache. I have Windows 7 and went to the link above "Note: Windows Vista and Windows 7 users see this info to find your Cache folder in WoW's Virtual Store." I found a intro page to Blizzard forums and can't find anything related to my cache. What do I do now?
  • #1324
    Thank you for this great addon. I have three questions concerning it:
    1) Does the number of NPCs being tracked have an impact on performance? If I add several NPCs to the list will it slow my PC down?
    2) Is there a way to input a zone (I mean specific zone, not just continent) when adding a new NPC to track?
    3) Is there a way how to import the list of tracked NPCs from one character to another?
  • #1322
    I'm using this addon to look for the Time-Bound Proto Drake. Does your hight affect if the addon will detect the rare mob?
  • #1323
    Nope, you can fly as high or low as you want.
  • #1315
    And how can I bind a macro to my mousewheel?
  • #1321
    BindPad will let you bind keys or the mousewheel directly to macros:

    Nice addon, but I also have a problem.
    When I add a new one, or when I see in the list it already has him for scanning. It doesnt show the colors on the map from where it can be. Is there a way I can fix this?
    Or is this overlay different from this addon? That it scans to it but that it doesnt show the colors from where it could be?
    I got this problem with Lil'timmy and the Mysterious Camel Figurine.
  • #1318
    Most level 61+ rares have maps, but not all of them. The camel figurines don't have a map because they spawn all over Uldum and their path would cover a lot of the map.
  • #1313
    Nice addon... but...
    Is there a way to IGNORE dead rare mobs? its kind anoying ot get the hit on useless corpses... and please make a way to clear the mobs from ingame...
  • #1317
    WoW manages the cache automatically, and addons can't influence it at all. The only way to (legitimately) affect the cache is by deleting and clearing it out of game. :(
  • #1319
    So the addon just scan the file for changes then? it dont activly looks around you in the world ? Is it possible to make a addoncontroled db from it? and use the setting in that to trigger the alert? Do wow update the cache file with last seen date or is it a one off...

  • #1320
    Yep, _NPCScan just sees when a new mob gets added to the cache. The last-seen date isn't available, only whether it has or hasn't been seen since the last cache reset. Also, it can't tell if you found the mob dead or alive, or even if it's a tamed hunter pet versus a mob in the wild. It can only go on where you found it at for the purpose of filtering what alerts show up.
  • #1312
    For _NPCScan users:
    To automatically clear the cache every time you start WoW, you can make a BAT file with the following:

    del "\Cache\WDB\enUS\creaturecache.wdb"
    start /D "" /B Launcher.exe

    replace with appropriate values and make sure to include the drive letter.

    Now start wow by clicking on this BAT file instead of directly on the launcher.

    The forum link seems to be outdated and the forum post is lost. So how do i exactly clear cache on windows 7 64bit? Sorry if this has been answered already, i searched the web and found tips but no solution.

    Thanks in advance
  • #1316
    The steps for clearing your cache on Windows 7 are the same as in the description, but your cache might be saved somewhere else. If you can't find the cache folder, try searching your entire computer for a file called "creaturecache.wdb". That file should be inside of your cache.
