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.

    No custom mobs. No mobs at all, blank list.
  • #1302
    Any way to put in opposition faction players?

    Trying for 'slayer' achievements.. and do you have any idea how rare some PVP combos are-- like-- orc mages?

    they are the 1 in a few million players... if I could get an alert one was around.. but they don't have ID #'s so I'm guessing-- no
  • #1304
    Not by ID, but there is a mod called EnemyScanner that watches for enemy players using the combat log. Not sure if it shows races though. Here's a link:

    I can't get it to show me anything in the lists. I was right on to of The Razza this morning and it didn't sound an alert. I'd love to own Skoll and was hoping for some help. Below is the error message I get when I type /npcscan.

    Only level 61+ rares are tracked by default, so you would need to add low level rares to see their alerts. You can download a settings file that includes all known rares from here:

    As for the error, you'll have to upgrade _NPCScan.Overlay. The current version for that is
  • #1298
    And if you must remain in the zone how close to the NPC do you have to be for the alert to go off/
  • #1300
    You have to be within targeting range of the rare to detect it, which is usually about 100 yards.
  • #1297
    DO you have to remain in the zone the NPC respawns in or will the alert go off if you are anywhere in Azeroth?
  • #1296
    I was flying around Sholazar Basin trying to complete Northern Exposure when King Crush popped up in NPC_Scan. The problem is I was not near its spawn/roam areas. I was actually right on top of Loque'nahak's spot at the upper NE corner of Sholazar Basin. I flew around all of King Crushes spots spamming /tar for him but he was nowhere to be found. Any ideas?
  • #1299
    You probably flew over someone who had him as a pet.
  • #1295
    I was just wondering if anyone knows a way to delete a single npc out of the craturecache file?
  • #1293
    Will i get a npc found message even if the rare mob is dead?
  • #1294
    If you find a rare's corpse before it despawns, yes.
  • #1289
    Anyone else having the issue of it not working on Northrend creatures? Three times in the last few days, I spotted Northrend rare spawns but the program didn't alert. I made sure my cache was deleted beforehand and I didn't previously have the kills in my Frostbitten achievement. I even went so far as I found one, exited Wow completely, deleted cache, came back in and it still didn't alert when I was standing right next to the creature. This happened on Vyragosa, Loque'nahak and King Ping. I later located a rare mob in Uldum (forgot his name) and the program alerted correctly.
  • #1290
    There's a checkbox on the Frostbitten tab to enable that entire achievement; Is yours enabled? The tab checkbox should show a red "X" if it's disabled instead of the normal empty box.
