Like with most of these Chelsith nameds, there are 5 copies of the placeholder scattered inside and outside the same style building (2 floors, upper is open to the air.) The fear is typically annoying altho I noticed I did not acquire aggro from any mobs I passed to return from being feared. Actually I link my auto-invis AA to my forward movement button which probably helps.
it spawned for me on the top of that building shown. It paths a little up there from the east side to the west side, that's it. location is approx. p2100 x n190 x p360 ( 2nd floor). Am trying the others. will add if I find out
