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.

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.

    When you clear your cache, do you completely exit WoW first? If you leave it open, even at the login screen, the cache won't actually clear.
  • #1360
    Guess your are using vista? and you only cleared the WoW cache?
    Then you need to go to c:\Users\%Username%\AppData\Local\VirutalStore\Program Files\World of warcraft and delete the cache file there also if Im not completly mistaken.

    I don't know if this will work, but I'm posting a link to a screenshot.  This screenshot shows me searching my entire drive C for the words "VIRTUAL STORE" and finding absolutely nothing.  I'm using Windows 7, and there's no need to be rude, Xiliath, I can read just fine (and that link DID dead-end when they updated the forums.)  I updated to Windows 7 after using XP for years, and am not sure of the exact date when I switched vs when I started encountering this cache problem.

    It even says so in the description... you need to learn how to read.
    "Note: Windows Vista and Windows 7 users see this info to find your Cache folder in WoW's Virtual Store."
  • #1363
    In his defense, that link doesn't work since the purge of the forums. Just takes you to Thank you for posting the actual location for the virtual store, I wasn't aware where the other location mentioned was either.
  • #1358
    Thanks for the great addon.
    Just a suggestion, a cosmetic one. On the map and where it shows the NPC's and their locations, the one in the corner where their names are displayed, maybe instead of making that box move when you mouse over it the names you could click on their title and it could display the little mini image of that rare as well, just a suggestion.
    But thanks again awesome addon, helped me find most of my NPC's on my huntard that I would have normally flown over.
  • #1357
    First, thanks a lot for your great addon!
    Now my question: When the alert pops up, i don't always want to kill the mobs right now, but if i close the window, it will adds the mobs to the ignore list. So can you add another button that will just remove the window without adding the mob to the ignore list ?
  • #1366
    WoW does that ignoring on its own; The only way to reset it is to clear your cache.
  • #1356
    I added a new cata rare the other day to the list using its name and ID# from wowhwead and the mob spawned in front of me the next time I loaded my my toon and no alert sounded. I added it ingame so maybe it cleared my file so i'll check it. I've been adding rares this way forever and it always kept them before. Is this great addon broken?

  • #1354
    I added several of the lower level mobs to the NPCscan, but when I change characters, they are not in the database? Is there any way to fix this as I don't want to have to type them in on every char I own.
  • #1352
    I have made a custom list of rares to look for. This has worked perfectectly for 18 months now. About a week or so I stopped getting alarms. I cleared the cache with no improvement. Then I noticed the _NPCscan.lua which holds the list was reset to the original version (2K, my custom version is 15K). Whenever I delete the 2K file and replace it with the 15K, NPCscan now automatically replaces my 15K file with the standard 2K one. I made my file editing the lua and that has worked perfectly up to about a week ago.

    Anyone know whats going on?
  • #1353
    Update: The _NPCscan.lua has changed it format. Once I had changed my file to the new format (and remembered to do the fileswitch while NOT running WOW) it loaded my custom mpc list just fine.
  • #1350
    I've cleared my cache at least ten times in the past few days and it is still showing that the mobs are cached. I even deleted the addon and reinstalled it and it STILL shows they are cached. I don't know if this is related to this problem, but one time when I deleted the Cache folder it didn't show up again where it should be. The next time after I logged out of WoW there was no Cache folder in the World of Warcraft folder: but there was one inside of the Data folder within that. Please help me fix this - I've been missing chances at mounts!
  • #1372
    You may want to disable a feature in windows what happens is folders that change your the time like the cache folder windows can restore it back from a older version I am unsure if windows xp does this but to find out you need to open the wow dir and Do Propeties on the Cache folder and see if there is a tab called Previous versions The feature is called System Protection I was getting this problem too I was so I just disabled it as I delete the cache folder very very often

  • #1349
    would be nice if you could actual remove any rare spawns from the cache that spawn in Sholazar. King Krush and loque are stuck in my cache, pulled the entire addon out remove it total. Did a fresh install and they still list as cache and the in game options menu will not allow me to remove them either
