Falmer Skulkers are a type of falmer in The Elder Scrolls V: Skyrim.
The sixth strongest type of Falmer, Skulkers are found in Dwemer Ruins and caves, usually assisted by a few normal Falmer or fighting alongside higher-level Falmer such as Gloomlurkers or Falmer Nightprowlers. Although they don't wear much armor, they have larger health pools than normal Falmer and can cast spells such as Ice Spike and Sparks, which can quickly slow down and overpower the Dragonborn in close quarters. Therefore, it is best to take Skulkers out from a distance before they can close in.
