Cave is not the same one as Gurgamath is at. This one is south of the main path from the swamp.
Go through a path at:
15.9S 42.2W
Cave entrance is at:
16.6S 42.1W
Its an instance so you can agro some trolls at the end and just run in.
Once in the cave follow till you get to an open room with a waterfall. Go into the waterfall and the tunnel continues on.
Go down the tunnel southwest to a tunnel heading west. Follow that tunnel.
This is when you start to see the weapon chests as well.
Boss is at the end of this tunnel on the left with alot of other mobs around.
I recommend a full group or high levels with you...and a long time to kill.
