Anor Londo

The sunlit city of the gods. Silver Knights, the famous archers and Ornstein and Smough stand between you and the Lordvessel.

Suggested level: 40–50

Bosses

Ornstein and Smough: Use the pillars to split them up. Whoever dies last absorbs the other and drops its soul (Ornstein also the Leo Ring), so you get only one per cycle.
Dark Sun Gwyndolin: Close the gap down the illusory corridor, ducking behind the pillars to dodge his magic arrows. Killing him locks you out of the Darkmoon covenant.

Bonfires

Anor Londo
Anor Londo Central Room
Darkmoon Tomb
Chamber of the Princess

Walkthrough: Anor Londo

Sprint by the Sentinels to the first building. Its bonfire (Anor Londo) is tended by the Darkmoon Knightess, who can strengthen your Estus Flask.
Head back for the pair of Sentinels you skipped; once they fall, their chest gives Demon Titanite.
The other two Sentinels guard the courtyard. Of its two chests, the right one is a mimic hiding the Crystal Halberd (use a Lloyd's Talisman); the left one is real and has Twinkling Titanite.
Ride the elevator down and kill the lightning-breathing Gargoyle on the rooftop.
Open the chest below for Demon Titanite, then walk up the buttresses into the chapel.
Walk along the rafters and hit the chandelier chain as you pass.
Hop down to the statue platform and roll through the pillars on the far side. A Painting Guardian guards a chest with a Divine Blessing.
Turn the lever once counter-clockwise to lower the platform, then kill the second Gargoyle.
The grand staircase is guarded by Sentinels and Batwing Demons; fight your way up.
Walk up the buttress and kill the right-hand Silver Knight Archer. Roll toward him rather than blocking until he switches to melee.
If you dare, kill the second archer on the other ledge for a Soul of a Hero.
Drop down past the first archer and go through the left door to light the Anor Londo Central Room bonfire.
Talk to Solaire of Astora here.
Cross the hallway and open the chest for Sunlight Medals.
Down the corridor, go through the left door and strike the illusory wall in the fireplace.
In the basement, open the four grouped chests for Havel's Set, Havel's Greatshield and the Dragon Tooth.
One chest down there on its own is a mimic; a Lloyd's Talisman puts it to sleep so you can take the Occult Club.
On the floor above wait two more mimics. Calm each with Lloyd's Talismans to collect Silver Coins and a Gold Coin.
Shoot the Titanite Demon from above until it dies.
A Silver Knight archer guards the far end of this hallway; take it out.
From the dead archer, take the right door up to the roof. A Silver Knight hides behind the door.
Deal with the archer to your right, then use the left-hand stairs: Siegmeyer of Catarina is waiting below.
Lure the four Silver Knights out of the room one by one and kill them.
Report back to Siegmeyer once the knights are gone; his thanks is the Tiny Being's Ring.
A chest inside the knights' room holds a pair of Demon Titanite.
Open the locked door from the inside, return to the rooftop and descend the staircase the archer was guarding.
Two Silver Knights patrol the hall beyond. Beat them, loot both chests for the Silver Knight Set and unbar the door that leads back to the bonfire.
Go back upstairs to the top of the great hall, circle the walkway and go down to the Giant Blacksmith.
Open the chest behind him for the Hawk Ring.
Talk to the Giant Blacksmith. Buy Titanite Shards, Large Titanite Shards, Green Titanite Shards or Twinkling Titanite, and make lightning or boss soul weapons.
A Titanite Chunk lies by the gate to the grand staircase; open the gate while you are there.
The Dragonslayer Greatbow sits on a ledge outside a broken window upstairs; hop out to grab it.
Return to the great hall and open the main door.
Top up at the bonfire first if your flasks are low.
Defeat Ornstein and Smough.
Solaire of Astora can be summoned near the steps by the archer in the great hall.
Hoping for human helpers? Their signs show up most often near the bonfire in the room past the archers.
Kill Ornstein first if you want the Soul of Smough (for Smough's Hammer) and his set from Domhnall.
Kill Smough first if you want the Soul of Ornstein (for the Dragonslayer Spear), the Leo Ring and Ornstein's set.
Ride one of the screw lifts and light the Chamber of the Princess bonfire.
Talk to Gwynevere, Princess of Sunlight, to receive the Lordvessel. Join the Princess's Guard if you wish.
Optional co-op around levels 40–50.
If Lautrec killed Anastacia, return to the great hall and use the Black Eye Orb to invade him.
Defeating him gives the Ring of Favor and Protection, Anastacia's soul, a Souvenir of Reprisal and Humanity.
At Firelink Shrine, use her soul to revive Anastacia of Astora, or use it as a Fire Keeper Soul.
Once Lautrec is dead, the Favor Set appears on the balcony above the Ornstein and Smough arena.
With the Lordvessel you can now warp between bonfires. Warp to Firelink Shrine.
Talk to the people at the shrine:
Talk to Griggs of Vinheim and Big Hat Logan.
Answer yes to Siegmeyer of Catarina to get the Emit Force miracle.
Hoping to become a Darkwraith later? Then leave Kingseeker Frampt alone for now.
Visit Domhnall of Zena under the aqueduct to buy boss armor.
Ride the crow back to the Northern Undead Asylum.

Walkthrough: Painted World of Ariamis

In Anor Londo, take the lift down, spin the platform lever counter-clockwise and walk into the chapel.
The chapel holds the Great Magic Weapon sorcery, the Black Iron Set, the Greatsword and the Black Iron Greatshield.
Examine the large painting while carrying the Peculiar Doll to enter the Painted World of Ariamis.
You land beside the Painted World of Ariamis bonfire; kindle it before exploring.
Use ranged attacks on Engorged Zombies to avoid toxic.
Climb onto the roof of the first building and shoot the two Crow Demons on the far tower so they come to you now instead of ambushing you.
Drop down for the Dried Finger, then go to the ground floor for a soul.
Clear the next building; two zombies hang from a ledge. Hit the rope holding the third zombie to drop it.
On the upper floor, a jump across the gap reaches a soul and the Egg Vermifuge; slide down the ladder after for the Painting Guardian Set.
Pull the Crow Demons from the tower one by one so you never fight more than one.
Climb the spiral staircase for the Red Sign Soapstone and drop to a ledge on the way down for a soul.
An Undead Dragon blocks the bridge. Once it falls, the bridge offers a soul, a Dragon Scale and the Bloodshield.
Through the tower's fog gate is a door that loops back to the bonfire; unlock it.
In the basement, pull the six Wheel Skeletons one by one with your bow and kill them.
Pick up the two souls, then work the lever that unlocks the gate on the way to the boss.
A false wall here hides tunnels with three Wheel Skeletons and the Annex Key; a special Engorged Zombie there drops the Fire Surge pyromancy.
Exit via the well ladder. Upstairs is a Ring of Sacrifice, and the zombie you cut down earlier carries Humanity.
Unlock the annex door with the Annex Key and go up the stairs.
Two Crow Demons wait on the rooftop to the left, and two more swoop in. The Vow of Silence miracle is the prize.
The Black Set waits inside the round tower; follow the stairs up.
The Dark Ember sits in the lower part of the annex.
Smash the wooden fence to reach Velka's Rapier; a drop into the building below gives a Gold Coin.
Return to the bonfire and restore your humanity.
As a human, linger in the spiked courtyard until Xanthous King Jeremiah invades. Defeating him gives the Notched Whip.
Souls lie around this courtyard, and a hidden nook behind a wall has the Acid Surge pyromancy.
Go through the gate you opened, cross the bridge past the zombies and kill the armored knight guarding the end for a Large Titanite Shard.
Reload the game before entering the boss fog; the Xanthous Set then appears nearby. Pick it up.
Talk to or fight Crossbreed Priscilla. She is peaceful unless you attack.
Cut her tail during the fight for Priscilla's Dagger.
Optional co-op around levels 55–60.
Jump off the bridge ledge to leave the painting and return to Anor Londo.
Outside the chapel, spin the lever clockwise to return the platform, then go back to the first Anor Londo bonfire.
Warp to the Undead Parish and give the Dark Ember to Andre of Astora.
Next, return to Anor Londo and set off for The Duke's Archives.
