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.

    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.  :)

  • #1003

    Just pushed the new version that has most of the rare mob locations that WoWhead currently has location information for. It took a bit longer that I had hoped to get it finished, as a series of small things kept cascading the delay.  I'll recheck its mob info periodically and push updates as needed.

  • #1008

    thanks for the update buttttttttt it missing the rares that drop the mounts :(

  • #1013

    It should have had them inculded if there was location data for them at WoWhead.  I'll do a manual pass in a day or so to add them.

  • #1004

    Something seems a bit wrong, it hides all paths unless Overlay > "Always show all paths" is checked.  I tried checking and unchecking show paths on map.  Is it checking to see what rares we got?

    This is true for all zones and rares.  Running Overlay and Scan of same version.  Thanks for your hard work!

    Its probably from the integration from NPCScan. Pre-WoD it would hide paths for mobs that were all ready found in the cache, but as that functionaly broke, I'm guessing that NPCScan is telling Overlay to hide the mobs.  I'll look into it this evening and see what is happeing.

  • #1001

    Any idea when WoD zones will be supported by this overlay addon?

  • #1002

    I'm hopeing by this evening or by tomorrow at the latest. 

  • #1000

    I am having one weird thing happen to the overlays. The 100m circile on the map and mini map keeps disappearing and becoming uncheacked even when I do it.. It this because of Draenor?

  • #997

    My overlay doesnt work.

  • #998

    There are currently no mobs for Draenor added yet.  Check to see if it shows overlays for older zones.

  • #999

    It does work for mop and back just not draenor.

  • #996

    Is there a way to show the rares that drop mounts in Draenor on this? Would be really helpful. Thank you for the wonderful addon though, I use it all the time :)
