Quelaag First New Any%

This is an Any% route using Sorcery. The first boss killed after Asylum is Quelaag in order to leverage Soul of Quelaag for more powerful spells to defeat O&S more quickly/easily than in other Sorcery routes.

Start Sorcerer, Master Key

Pick up everything in Asylum, Demon with Dagger Plunging and 7 Soul Arrows, don't quitout at the door, you want the Humanity
Bombs and Bones from Firelink, use a Bone on pickup.
Valley start, pick up all souls (including the New Londo Ruins soul), RTSR, Grass Crest Shield (GCS)
Pop the Humanity from the Asylum Demon
Kill up to 3 Demon Trees using 2 Firebombs each looking for Purple/Blooming Purple Moss, but keep going if it doesn't drop

Ring the Bell, Homeward Bone

Go to Undead Burg, talk to the Undead Merchant and buy the Residence key
LUB Skip (balcony method) and rescue Griggs, Homeward Bone
Buy Homing Soulmass, Soul Spear, Great Heavy Soul Arrow (Soul Spear can be omitted if you would need to dupe too much! If it is, just use Great Heavy until after O&S, but you do need both Soul Spear copies for Hydra and the DLC, so you'll still buy it eventually.)

Take the Elevator to the Parish
