WALLPASS.ITM

WALLPASS.ITM is a NPC-only item in several game versions, including BG2, BG2EE, ToB, and SoD. 
== Effects ==
This item allows creatures to pass through otherwise impassable walls, objects, and other creatures.
More commonly, this item is bestowed and equipped by a non-player creature so that they can be positioned on an area map within an otherwise impassable area. 
An example of this would be Carston, placed inside the Machine of Lum the Mad, an impassable zone on the area map.
Other examples include animals placed in impassable cages in Waukeen's Promenade, or slaves in pens within Ust Natha, or even Killer Mimic creatures within chest containers etc.
