So, Angel of Marksmanship lets you use two weapons, pistols and your fists... Since the Marksman Diamond denies you the opportunity to upgrade your pistol ability, I decided to work on the fists. :) (And considering I got Demonic Diamond recently, this was actually easier!)
My strategy was the same that I used for Demonic Diamond, (except that I was free to occasionally shoot people if I felt like it) :) get to the Chained Court as soon as possible and make those berserks last as long as possible and then farm Pain Elementals for health once I got Vampyre trait.
One story from this game I have to relate:
The most tense moment was at the end of level 11, because my berserk ran out and I was out of med-packs and armour and I hadn't gotten Vampyre yet. (Level 5 with 99% of the way to level 6!) :| I found myself caught between an Arch-Vile in one direction and a Commando in the other. Given that choice, I ran toward the Commando, side-stepping repeatedly to dodge as much of his fire as I could, and then just as I spotted the stairs, a freakin' Arachnotron came into view and I was getting plasma barrages from two different directions! When I was 1 square away from the stairs, I was at 5% health and I stared at the screen for a long moment and said to myself, "There's no way I'm going to survive that last step..." but I must have been channeling Jules from Pulp Fiction because I took that last step and two barrages of plasma fire missed me completely! :o
I went downstairs to level 12 and my hopes died again because I started surrounded by sergeants, imps, a couple of Hell Knights, and a commando. So, I did the only thing I could do: Punch out an imp to bring myself up to level 6 and get Vampyre trait and quickly run around the corner into an alcove out of their view which was luckily empty except for a former human who I punched out too. The commando followed me, so I corner-shot him almost to death and finished him off with my fist. I then stood there for quite some time between the commando, former human, and imp, knocking them down any time one of them got up and slowly got my health back. Things briefly got tense again when another imp came around the corner and destroyed the former human and commando bodies, but I was able to lure the imp over, along with one of his buddies, and soon I had 3 imp bodies safely tucked away out of anyone's view and I could punch them out to my heart's content any time any of them got up. Once I had enough health to make me confident enough and I was zerking again, I charged out, found the stairs, and the rest is history. :)
So, that's it! God Hand skill rank! WOO! :D I can still remember when I first discovered this game almost a year ago and Diamond Badges seemed impossible. (Win Nightmare difficulty with only your fists? How ridiculous! No one could do that!) :P I'm hoping I can be an inspiration to people to show that it really is possible! Once you realize you have the ability, you might as well aim high. :)
