Undead Asylum Revisit

From Firelink Shrine, travel to the Crow's nest. You can reach it by jumping off the lift to the Undead Parish near the bottom, climbing the tower, and resting in the nest to be transported back to the Asylum.

Kill the Torch Hollows encountered on the way down.

Run through the small door in the boss room and proceed up the path to find a Black Knight. Defeat it to obtain a Red Titanite Chunk.

Continue onwards to find Oscar, who has now gone Hollow. Defeat him to receive the Crest Shield.

Make your way to the Bonfire before the boss room. Enter the room and ensure you pass over the green-looking stones; the floor will crumble, leading you to a boss arena. Heal immediately upon landing.

After defeating the Stray Demon, climb the ladder in the corner to exit the room. You will find yourself back where your journey began, with a Black Knight near your cell. Defeat this Black Knight to receive another Red Titanite Chunk.

Inside your cell, you will find the Peculiar Doll, which is necessary to access the giant painting in Anor Londo.

Make your way back to Firelink Shrine. Before reaching the Crow's nest, visit Snuggly. Trade the Rubbish item (picked up at the start of the game) by dropping it in the center of the nest. Quit and reload the game to find your Rubbish has been transformed into a Titanite Chunk.

Return to Firelink Shrine to level up to level 57 with 13 Intelligence.
