This is how Sbdajpplifrozk defeats gremlins. You play dead and let them feel so bad about becoming mass murderers, they go and commit honorable suicide by standing inside a mass of painful jade tangles.
See all those items? All of them were dropped by the ever-so-depressed gremlins as they saw the pools of blood on their hands and hammers from killing all four of us. They couldn't live with the thought of becoming such terrible people, they dropped all their items and shuffled off this mortal coil.
We got up about five seconds afterwards and collected the loot.
They obviously haven't updated the AI to account for the spikes/tangles doing damage to the NPC's =P
