About _NPCScan.Overlay

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.Overlay is an addition to _NPCScan that adds map overlays for rare mob patrols. When you search for a rare in _NPCScan, _NPCScan.Overlay will show where it patrols until you find it. It works similarly to keithgabryelski's Rare Spawn Overlay's , but supports the minimap and has a much smaller download size, along with a few new features.

Special thanks to Rare Spawn Overlay's patrol paths and Routes minimap drawing code for inspiration!

Note: _NPCScan.Overlay can integrate with _NPCScan if you have installed it, but make sure to keep both up to date if you do use both!

If you have a question check the FAQ, or a problem create a ticket


World Map

In addition to drawing paths on the World Map, _NPCScan.Overlay adds a key to a corner of the window with each rare's name. It only appears in zones that have rare maps, like Netherstorm as seen in the screenshot. Hovering over a mob's name in the key will cause the mob's path on the map to start flashing. If you need to read something under the key, it can be toggled by Clicking on the Key Toggle button on the map. The key can be repositioned by just moving your mouse over top of it while holding the shift key and the key will jump to a different corner.

Most map mods like Atlas will inherit the key and overlays from this module. Even Carbonite's map display will show them.

Battlefield Minimap

The small “Battlefield Minimap” (AKA the “Zone Map”) also shows mob paths.


All shapes and sizes of minimaps are supported. Rotating minimaps work fine as well.

One feature not shown in the screenshot is a thinner 100 yard range ring around your character. It helps you gauge _NPCScan's detection range, so you can sweep through zones more effectively. This option can be found in the Minimap subsection of the options panel, detailed below.


_NPCScan.Overlay's options can be found under _NPCScan's main options menu, under _NPCScan > Overlay or as its own entry of _NPCScan.Overlay if _NPCScan isn't installed. This panel can be opened with the “/npcscanoverlay slash command, or “/overlay” for short.

The “Always show all paths” checkbox at the top of the pane overrides the instructions of NPC tracking mods like _NPCScan to hide unused paths, and always displays all known paths instead.

The rest of the configuration pane lists each map display's options. You can enable/disable each map from here, as well as configure individual settings for them.

Each map display can have its overall transparency set independently with the “Alpha” slider, so that it doesn't obscure the maps themselves.

James D. Callahan III:
    - Don't change the map's zone while the map is open. Fixes ticket #48.
    - Cleanups on accessing global variables/functions.
    - Minimap_Toggle => NPCScanOverlayMinimap_Toggle because what the actual fuck was the purpose of giving a global function such a generic name?

    Since Carbonite updated today, the mob paths for all rares don't show up on Carbonite's minimap. 

  • #1021

    Hi, seems this addon doesn't work properly on Outland's Nagrand & Shadowmoon Valley.

    The colored areas look fine on the world map, but doesn't show up on the minimap. Also, the 100m circle disappears the moment you enter one of those two areas & reappears once you're out

  • #1018

    Why are not important rare integrated? Pondfist etc.(all mount dropped rares)...

  • #1019

    Because at the time I did the last data pull from WoWhead there was no location data for those mobs and I haven't had the time to do another pull and manually add & update mob locations.

  • #1020

    I look forward to this update! Tyt :)

  • #1017

    Gorum note in SMV is in the wrong spot.  Refer to wowhead comments for details.  My coords were 21.5, 33.1.

  • #1016

    Sorry for ask but i have problem with blue zone on the map for quest if you know what i mean. when i disable NPCscan_overlay bluze zone come back. SOme1 else have same problem?

  • #1015

    Hep hey

    I have a couple of things i think this needs to be updated with:

    1. One time kill rares should be removed from the map, when killed.
    2. Need the rares that drop mounts to show up on the map. You can see a list of them on this first comment here:

    Hope you will address these two things.

  • #1014

    Hello, not seeing a listing for Pathrunner in Shadowmoon Valley. Anyone know why? Just wondering why that is.. Thanks!

    hi folks,

    after NPCscan has lost its ability to "track" already seen NPCs in the wow database files, there needs to be a new method to track.
    NPCscan or NPCscan.overlay needs an own tracking database, maybe with only the NPC ID of every seen NPC as content, or with the NPC ID and a boolean. but the current status is very awkward.

    i would vote for a database that tracks NPCs and the user should have the options to disable tracking on NPCs that have been:

    - seen
    - killed
    - tamed

    and an checkbox at each NPC to disable this NPC manually.

    just my 2c

    Areed.  I'm hoping to update NPCScan to track the WoD vignette kills, but that is going to take a while due to needing to map 200+ mobs to their corespondig quest id to check against.  Creating an internal tracking DB like you suggested could possible but it is not somthing I currently have plans for in the near future.

  • #1009

    So who thought that this was a good idea?

  • #1011

    When NPCScan was originally created, there were only a dozen or so rares in a zone.  Now some zones have 40+ rare mobs and it wasn't really designed for that many. The whole key UI needs to be reworked to provide a better experiance and to handle the increasing number of rares.

  • #1005

    Silly point, but could you add a direct link to npcScan from this addons description?  ^

    You link other's work, but not your own.

  • #1006

    Hmm, never realized that it did not.  Now it does.  :)
