I was a level 27 warrior messing around in citadel, found the hole and dropped down...*falling down in the air, get two hits by this mob and "dead" before i hit the ground* >_>
Recently, a friend of mine and I were messing around in Garliage Citadel. I'm 65RDM and wanted to see if I still aggro these things, so I drop sneak and invis and start messin around. Friend is a 62THF so he does the same. He caught aggro so it's fight time. Kill both by gate #2 and one dropped a Garliage Chest Key. Noticed that no where that I looked had that info that these drop the chest key (not coffer) so I'm adding my 2 cents.
