Contrary to the promise I recently made myself, I just gave up on my MVm build going for the first Mortuary attempt: I suicided in the City of Skulls, having killed the agony elemental and all pain elementals - except for one, which made sure the swarm of lost souls that remained was kept fresh.
Not counting bad luck, the City is the level which has gotten me killed most by far, so much so that I actually skip it most of the time. Kills almost always happen when the agony elemental has been summoned, or even already killed. This time I had a missile launcher for long distance whoop-ass, and my B-modded chainsaw (BRU3,FIN1) prepared to mop up the rest. I had a B-modded red which was still well over 100% when the AE was summoned.
Apart from the City of Skulls, the run was going great, even after a sloppy start. I had half a mind to savescum the entrance, and I'm actually sorry I didn't do it, because it would have simply allowed me to do some trial runs in order to see if I can make something of this.
The obvious beauty of MBM aside, any tips on taking on this bastard and it's grinning offspring?
