AF 5(?) lvl56 coffer question

[Moridan]

The guide says the mob that drops the key, but not where the mob is located. Like, what zone and where within? Much appreciated.

if you are speaking about the circlet, its in garliage you drop the one of the holes (Down to where chamber beetles and serket hang out) and you look for the skeleton mobs there i cant remember their name but i know they are pretty hard at lvl (hell mines are drop them but leave them alone unless you like dying)

[Demetrios]

From my experience the Weapon type monsters located in the Garlaige sub-level have greatest chance of dropping Coffer keys, but it could have been a fluke.

Fallen Mages and Warriors are good for key hunting, not too tough for your level. You can find these by dropping down to the large room below, somewhere in the south/south-east corner there is a little tunnel between 2 large rooms you can pull from.
