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.


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 wrote a small script using autoit that automaticly exits wow and  deletes the cache files and then launches wow . saves alot of time i just want to share it, and its for those who dont know how to clear the cache makes everyt hing easier..


  • #1654

    autoit is tracked by blizzard as a bannable program if not used properly cause of botters sadly - use at your own peril

    You are right and then you are wrong, Autoit is only detected by people who write the scripts to scann memory , other then that autoit is not detectable or i would have been banned along time ago. long as dont use it to scan memory   its fine.

    I would like to disable the raid marker feature.

    It's not needed to locate the mob and all it does is draw attention to the mob if there happens to be someone closer to it than I am.

    This has already happened once.  As soon as the mob was marked, it caught the attention of another player and they killed it before I could get into range.

    I enjoy using this add on and I appreciate the work that you've put into it but I feel that the raid marker is unnecessary.

    I feel confident enough to modify the .lua file if I need to and it would be great if you installed a button to allow players to toggle the raid marker off and on.


    Thank you!

    They got the attention not because of your raid icon, but because they also have npcscan blarring loudly at them. Even if you turn your raid icon off, all the other players still have it turned on. Perhaps you are asking for a feature request to make raid markers off by default so noobs that install this addon do not know they are at a disadvantage and give you a better fighting chance.

    Umm, No. The only people who can see your raid markers are people in your group/raid.

    I have a problem.

    The in-game NPCScan chat message told me that I could clear the cache manually or through the /npcscan menu. So I went to the /npcscan menu, opened the search table, sorted the creatures according to the "Cached" tab, and started clicking the minus button one after the other (assuming it was the clear cache tab). It turns out the minus button deletes the creature entry from the search table. I deleted a good 10-15 rare creatures from the search table and I just cannot find a way to revert to the default search table. I know I can add creatures manually but not only is that incredibly cumbersome, but I also don't even know which creatures I deleted!

    I cleared the cache file, deleted and reinstalled NPCScan and associated addons, but the search table just won't refresh. I know the table didn't revert because I do remember deleting Skoll - I was surprised that it was cached because I've been after it for some time and I've never seen it before.

    All help appreciated. Thanks in advance.

    Here's the solution for future reference:


    If you just want to restore them, delete this file while WoW is not running:

    World of Warcraft//WTF//Account//"your account name"//"Server name"//"Character Name"//SavedVariables//_NPCScan.lua

    This where the NPCScan saved any personal settings, deleting this file will remove all of those setting, including the changes made to the list.

    And your a fuckin dumb ass sorry for my language bant his person thats a wide spread word trojan l

  • #1639

    honestly... the there should be an auto-cache clearing option, or add time into the mix. lets say you found Rare mob X at 10:30. you can set a time in minutes in _NPCScan to not alert you to ame monster again for say... 30 min? and after 30 min, it would overwrite the original cached mob if you find it again with a new timestamp.


    Whether or not this can be done. it would be awesome

  • #1646

    i made a program that does it, cause cant clear the cache with wow running


  • #1640

    It cannot be done. Addons can't delete cache while the game is running.

    You can run WoW with a batch file that clears the cache, and restart the game every 30 minutes.

  • #1637

    a little trick i learned is you can make creaturecache.wdb to a read only file and you dont have to clear your cache anymore. After a relog, any rares you found are no longer in memory. Hope this is of help to some peopleWink

    I keep getting a warning when starting wow that several mobs are already cached yet I have deleted the cache file folder several times before starting and the message still appears.  What's goin on?  Is there more than one place that wow keeps its cache now?  I'm in Win 7 x64

    There is a Rare in Howling Fjord. King Ping is it's name. I have seen him south of Kamagua, where you do the daily for the tuskarr.
