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 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 Keybind->Other_>NPCScan 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 have a problem with npcscan. It doesn't go off when the window is minimized. If you use more than 1 account to camp for a spawn, or just so that you won't get bored, it's nice to have the windows minimized and do other stuff like watch Netflix. However, I've noticed that NPCscan won't go off then, it goes off when you open the window again.

    Would there be a way around this, or is this something that just cannot be fixed?

  • #1780

    Don't minimize, use windowed mode and put it in the background.

    It doens't work in minimize and have sound enabled. I just tested it and that rare in icecrown spawned and I didn't hear a thing.

    I have a few questions about how this addon works.

    Sometimes I log off with only a couple of creatures cached, I log on the next day and all of a sudden there are around 10 creatures that are cached. So my questions are does NPCscan cache creatures that others find/tame/kill? And if it does, does it cache them if someone finds/tames/kills them when I'm offline? Because if it doesn't then why are there more creatures cached when I log on than there were when I logged off?

    When hunting for frostbitten more than 1 time NPCScan not given allert 
    Sometimes it helps to delete Saved Variables  but i think it has something to do with what it cached.

    NPCScan: The following unit(s) are already cached: “Aotona”, “Crazed Indu'le Survivor”, “Griegen”, “High Thane Jorfus”, “King Krush”, “King Ping”, “Loque'nahak”, “Old Crystalbark”, “Putridus the Ancient”, “Syreian the Bonecarver”, “Terror Spinner”, “Tukemuth”, “Vigdis the War Maiden”, “Vyragosa”, “Zul'drak Sentinel”.

    and there i so of those i have chached i still missing to my Achivements

    Read what it says at the top of the page.

  • #1765

    i cant download it when i do it says installation failed can somebody help me?

  • #1764

    Is their a way to make NPC_scan make a sound if you're alt tabbed? If not... does anyone know if their is such an addon that does this? I hate being alt tabbed and npcscan goes off and then i tab back in 5 minutes later to find the rare mob dead :(

  • #1779

    The Client itself has an option to Enable "Sound in Background" in the Sound options menu. Checking this option will allow the audio from the game to continue to play even if it's minimized or not in focus.

  • #1763

    Totally useless without an automatic reset like Silverdragon.  I like your addon better in every way except that.

  • #1762

    I'm new with all this stuff here so i'm a little confused, I DL the addon and deleted the Creature cashe, what do I do after that? is that it, I didn't notice any changes when I logged in. I feel like I did somthing wrong.

  • #1761

    If people want stop clearing the cache, I know of a shortcut that I still use today and works great. 

    Go into your World of Warcraft folder where your Interface, WTF, and Cache file are located. Click Cache. Click WDB. Click enUS (or whatever file is located in the WDB. There is only one.). This will show you all the individual cache for the game. Delete creature cache. Then log back into the game, BUT make sure it is in an unpopulated area free of NPCs on your NPCscan. The log in creates a new creature cache.

    After this is done, log out, go back to the creature cache located in your WDB, right click the new creature cache file, click properties, and check the read only option, then click apply and then ok to close the file properties.

    This will remove the need to delete the cache every time you log out. When you log out of the game, the cache is automatically cleared of any NPC you may have found.

    This did not work for me. Is the premise flawed or is my attempt flawed? Tried it several times, any ideas? It sure would be nice not to have to clear cache every time I log on.
