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/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.

    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.
  • #1292
    Thank you, that was it. Mine was disabled, never noticed it before. Not sure how it got like that, but I re-enabled it and I assume it will work now. Awesome add-on btw!
  • #1288

    its kinda odd. I disabled UAC so WoW is installing its "Cache" Folder inside "C:\Program Files\World of Warcraft\". I have a "Virtual Store"-folder but theres no WoW Folder inside. After deleting the Cache folder and doing a search for "creaturecache.wdb", theres no such data on my system, even if i start WoW before.

    I dont get it, in game it says "finished" with a hook at the mobs i killed.
  • #1291
    It sounds like you're clearing your cache just fine. As for the green "finished" checkmarks (if that's what you meant), they track whether you've completed those parts of the achievements and are tracked separately from the cache. If you want to keep searching for those rares, you can enable the "Search for completed Achievement NPCs" option.

    I downloaded it for special pets (well, mainly Terrorpene and Sambas), but both times I found Terrorpene, it didn't pop up or make any noise (first time I lost it too a horde... bleh). It was the first time I had used the addon and have not found him except those two times. I know it works because it finds other NPC's, but not Terrorpene, otherwise it seems to work fine and I got my stupid turtle anyway :P

    Just thought I would mention that in case it happens to someone else :D
  • #1287
    Delete the creaturecache.wdb file after each WoW session. That way you can rescan creatures you have previously discovered. You can add it to a cleaner like CCleaner under Options/Include.
  • #1286
    Make sure to clear your cache if the pets you're after are cached. If you see a hunter with a rare pet out, WoW will cache that pet. Just be extra careful to check your cache any time you pass through a city.

    I've found a strange problem with the latest version of _NPCScan. Then I enter the game or change region, it prints "_NPCScan:" in the chat and also the timestamp if enabled, but no text after that (like list of cached NPCs for example).

    I thought it might have to do with my rather big list of NPCs I'm scaning for, but deleting the _NPCScan.lua in my wtf-sub-folders doesn't fix the problem.

    I'm using the German WoW-client.
  • #1285
    Oops, chat messages for all non-English locales has been broken since I added timestamps. The new version should fix printed messages for all languages.
  • #1281
    I got a problem with deleting the cache. I'm using Windows 7 64 Bit. My WoW Folder is in "C:\Program Files\World of Warcraft\". I deleted the whole "Cache" folder and restarted WoW..nothing the addon still remember the mobs i already killed. Then i deleted the addon + the cache folder, restarted wow and the addon still remember the data. Anybody know what iam doing wrong?
  • #1283
    First, make sure your game is turned off before you delete the cache, or else WoW will still remember what was there and put it back once it closes later.

    If that doesn't help, your cache might be in your Windows "VirtualStore". In this case, search your computer for a file named "creaturecache.wdb"; It should be somewhere inside of the /real/ cache folder that WoW is using, so delete that cache instead.

    Hi, Is there any way to turn wow sounds low or off but to still have npcscan alerts go off?
