When I first saw this Night Watch outside of Darkshire, I wondered what it was for? I found out rather quickly.
Stitches is a big guy that resembles the Stay Puft Marshmallow Man. He spawns after you complete Bride of the Embalmer and marches to Darkshire. He cuts the Night Watch up pretty easily.
He wasn't counting on help. With the assistance of a 32 Hunter, we melted down Mr. Stay Puft.
Too bad he didn't explode into a bunch of goo. That would have been interesting.
As with all of the Elite mobs in Darkshire, he drops nothing of value. Why is that?
