Can Someone help me? I'm new to this board, so I don't know if it's been covered or not, but how do I kill Marduk in the Aetherium? I have the mirror and I am reflecting his shots, but am I supposed to be reflecting them towards something(ie. The globe hanging from the celing, Marduk himself)? Where do I get the key for the strange keyhole?

You have to deflect his shots so that they comes back and hit him. After you defeat him for the first time, the key will drop off his neck. It's that pink thing.

from him when you bust his sorry little ass.

which you do by reflecting the shots back
at him

what this means is much jogging from the
low place to the high, and from the high
place to the low. You must be on his level
to reflect, and you can tell because like
with other weapons, he will change posture.

you have to get him good with a few of these
and then he'll drop ... well, sompin', which
I daresay you will be able to figure out
what to do with.
