There are a few other examples of multi-weapon Weapons, such as Gerwitz's Scythe, the DRK AF3 quest mob, and Ancient Weapon, a mob from Rise of the Zilart Mission 5.
Gerwitz's Scythe has a shortsword, a scythe, and a wand floating over its head. :D
Nah, lots of high level weapons have 3 weapons over their head (this one, as you can see, has a great sword, a staff, and a knuckle). There's another type of weapon in Ve'Lugannon Palance that has 3 weapons over its head as well, but I forget which.
And I was just unlucky to have found the coffer in a room with one of these; some of the rooms just have golems, and some just have dolls.
Yay they posted my pic. ^^ I was sooo lucky picking this coffer... got it open first try, and this guy didn't aggro even though he was only halfway across the room. I was so sure I was gonna die opening it, but I made it out fine. ^^
