First, start by grabbing the ring of sacrifice under the bridge. Then, reverse hollowing and head to Blighttown. Grab any and all souls shards on the way there. While in Blighttown, trigger the Mildred invasion and run into the bonfire room, then kill her. If you don't mind backtracking, rest at the bonfire. Then kill the slugs to get around 7 large titanite and 20 green titanite, 2 large titanite can be found in the level. Grab all of the large proud knight shards then head towards Quelaag. Summon Mildred and head into the fog. Lure Quelaag away so that Mildred can get some hits in, it may take a while for Mildred to kill her. Then, head into the Demon Ruins and cheese Ceaseless. Head into the lower Demon Ruins and grab the souls shards and the large fire ember, then homeward bone back. If you're still in Blighttown, feel free to grab whatever you need in the Great Hollow, especially Twinkling titanite and the Red Chunks. Head into the Catacombs and just run through using the shortcuts to get to Vamos. Buy as many titanite shards to upgrade the equipment, then make a Fire +5, or if you grabbed some Red Chunks, + 6/7. Kill (cheese) Pinwheel then leave the Catacombs. If you're feeling lucky, you can start New Londo, and get the Very Large ember and some titanite chunks. I usually do this. Then do Burg/Parish so you can get to the Depths. Or you can use the 2+ shortcuts to get to Lower Undead Burg early. Kill Capra and grab the large ember from the Depths. Kill Gaping, warp out, kill Gargoyles, then head back to the Asylum. Kill the Black Knights, Stray Demon, and Oscar. Upgrade your weapon of choice to +15 or Fire +9, you should have enough by now. Then just normally progress through the game. By the time you kill the Stray Demon, you should be around SL 50-60, and have the best upgrade or near best you can have for your weapon. If you'd like, you can do some PvP to level up, or you can just beat the game. If done precise, fast, and well, you can make a new PvP build in around 4-5 hours, without the use of a save editor.
Hopefully this helped people out that want to make new builds.
TL;DR, Blighttown first, Ceaseless, grab Fire Ember from Demon Ruins. Go into the Catacombs and make a fire weapon. Get to New Londo, grab Very Large ember. Finish up Parish/Burg/Depths. Kill Stray Demon, max/near max upgrade weapon. Finish out the game. If done right, this takes around 4-5 hours.
