As soon as I reach Firelink, I run down to New Londo. I use a Transient Curse and start farming the ghosts for a Jagged Ghost Blade. This can take anywhere from 3-100 kills, depending on my luck. Through all these kills, I obtain enough souls for the Sorcerer's Catalyst, Soul Arrow, and Heavy Soul Arrow. I pick up the Fire Keeper Soul from the three ghosts on the bridge. Now it's time to run through for every item. At this point I already have the Estoc and the two Transient Curses, as well as the Soul of a Lost Undead. Fire Keeper Soul comes next. I go break the pots and collect two more curses. I run up the stairs, across the bridge. I run in the room then go to the open area on the right. I stand there for about 3 seconds so the ghost blocking the door moves. Now I run down the stairs and grab the Parrying Dagger. I continue along, past the Fog Gate and grab the final two curses. Now I run through the fog gate and kick down the ladder. I pick up the Soul of a Proud Knight as no ghost will attack me while grabbing it. I continue along. I jump over the broken bridge gap, and grab the Green titanite Shard. I turn around and grab the soul, the continue along to the Composite Bow. Now I run back and grab the Humanity. I turn around, go on the roof, grab the Rare Ring of Sacrifice, and jump off. I run in, grab the Soul of a Proud Knight, I jump through the hole in the wall, turn around, and run to the Cursebite Ring. Then I commit suicide. I now have every item in New Londo, and I haven't even attacked any ghosts past the first part.
Next comes the Catacombs. I already know I'll need homeward bones for this area, so I jump down the elevator shaft and grab everything. I grab all the misc souls around Firelink, as well as reinforce my Estus and grab the Firebombs. Now I suicide run for every item in the graveyard, ending at the Binoculars. I turn around and run into the entrance of the Catacombs. I run down and turn the first lever. I don't kill the Necro, there's no need. I continue along and pick up the Lucerne. I then run through to the second lever, and grab the Soul of a Proud Knight behind me. I run across the bridge and roll off the side-- I kick off any skeletons that follow me. It won't kill them, but it will get them off my back. I run up and say "No" to Patches. I run across the bridge, through the Fog Gate, and down to the Darkmoon Seance Ring. I grab this every playthrough, no matter what the conditions are. I use it on every playthrough. Now I continue along, rage at the developer message that says "Up" and I grab TWoP. I go through the floor and do the same catacombs run I did before. I say "No" to Patches again, and I turn the lever. I run down. I go through and pick up the Great Scythe, then I use Soul Arrows or the Composite Bow to kill the Necro by knocking him off. I turn the lever, and run to the second Green titanite Shard. I consume some of the souls I have picked up so I have 8.4k total. I buy 9 shards, and upgrade a weapon to Fire. Normally the Great Scythe if I have 14 DEX, or the Lucerne. If I'm doing a STR build, I'll upgrade my starting weapon, which will most likely be Battle Axe. Now I run through and kill Pinwheel with my new fire weapon. I get the mask, and continue along. When I reach the third tomb you slide down, I slide to the right for a Humanity. I burst through Patches dialogue, and have him kick me down. I pick up a Large Soul of a Proud Knight (two of them), and the Skull Lantern. I homeward out with my 15k souls. I level up from here.
There is one more place for me to go before I can start the run.
First thing I do is open the door and grab the soul. I run through to the undead dragon, grab the Soul of a Proud Knight, Astora's Straightsword, and the Dragoncrest shield. I hug the wall and roll through his swipe. I continue along to the first Drake. I take a quick right and pick up the Humanity. I run out, cross the bridge, pick up the Bandit's gear, and climb the ladder. I grab the Red Tearstone Ring and jump off. I jump off so I will land next to the door, this will allow me to live. I run across the bridge and activate the elevator. I reactivate it so it goes down, and I continue along. I kill the BK by backstabbing him off, and I pick up the Grass Crest Shield. I run up and kill the Lizard. I continue and I parry Havel to death for Havel's Ring. I grab the Hunter Gear and longbow, then I kill the four treemen. I talk to Andrei and learn "Hurrah!", and I buy a Broadsword. I turn around and go get the Wolf Ring, I'm sure I don't have to describe that. I run back to Andrei and up to the Firekeeper Soul. I pick it up and go down the elevator. Almost done!
I reinforce my Flask and go down to New Londo again. I go through to Blighttown, my second favourite area, (behind Painted World). I grab the Key, and then down to the Crimson Armor. I don't bother with the Firekeeper soul as I like to keep Anastacia alive. I continue down to the swamp. I pick up the Large titanite Shard, and then the Large Soul of a Proud Knight. I go grab the Pyromancer gear, and the Poison Mist pyro. I pick up the other two Large Soul of a Proud Knights, then I run through to the Great Hollow, getting the Plank Shield and a Twin Humanity. I jump down to the Cloranthy Ring and go back to Blighttown. I start to go from the bottom up. I pick up the Wanderer gear and the Falchion. I continue up and grab the whip. Now comes the hardest part of my new run. I grab the soul and climb the ladder. I kill the Blowdart ***, and I run to the cave. I kill 5 Ghouls by kicking them off. I go down the ladder and kill the "Thing". I grab Power Within. I grab the soul, go up the ladder, kill the two dogs as well as a Ghoul. Then I completely go through Blighttown. It would take too long to describe so I will just list what I pick up.
Shadow Set, Iaito, Soul of a Proud Knight (2), Blooming Purple Moss Clump (3), Humanity, Eagle Shield. I homeward out with about 8k souls.
I have officially gotten almost everything I could possibly need for a new run. If I'm making a DEX build, I'll run back to Vamos and make my Iaito to +5, otherwise I'm good to go for Tauros Demon. I do this on EVERY new playthrough, and it normally takes about 3 hours.
