Walkthrough: Catacombs of Carthus

At Firelink Shrine talk to Hawkwood for the Farron Ring; reload if he is not on the stairs.
Reload again: he is gone and Hawkwood's Shield lies by a gravestone outside where the dog roams.
Eygon of Carim is now in the shrine; exhaust his dialogue so he can help in a later fight.
Enter the catacombs from the Abyss Watchers bonfire; Carthus Rouge x2 is on the left.
NG++ only: the Ring of Steel Protection+2 is on a pillar under the bridge.
Past the bridge go up the stairs on the left and turn back right for a Soul of a Nameless Soldier.
Turn back, take the ladder down and find another Soul of a Nameless Soldier.
In the pillar room hit the right wall to reveal the Carthus Pyromancy Tome.
A Sharp Gem lies on the right of the pillar room.
The next room holds Titanite Shard x2 in the far left corner.
Before the long staircase, take the hallway on the left to meet Anri, who is looking for Horace. Exhaust her dialogue.
On the platform beside her, kill a Crystal Lizard for a Twinkling Titanite and take Bloodred Moss Clump x3.
On the left of the big staircase is an Ember.
At the bottom, kill the hatted skeleton hiding in the next room; the rolling skeleton ball then smashes the gate and leaves an Undead Bone Shard.
In the next hallway, the Carthus Milkring hides behind big vases on the right.
NG+ only: the Thunder Stoneplate Ring+1 is among those vases.
The bone-strewn hallway holds a Large Soul of an Unknown Traveler and an Ember at its end; mind the hole.
Where the second skeleton ball starts is a Large Titanite Shard.
Light the Catacombs of Carthus bonfire in the hallway on the left.
Downstairs, right and right again into the Skeleton Wheel corridor for Titanite Shard x2 on the left wall.
At its end is the Carthus Bloodring.
In the main room a body by a pillar carries Titanite Shard x2.
Hit the wall right of that body and climb to the Grave Warden's Ashes.
Across the room on the right is a Large Titanite Shard.
Kill the hatted skeleton so the ball breaks and reveals a Dark Gem.
On the second level by the skeleton archer is Carthus Rouge x3.
In the tunnel past the hidden wall, a Crystal Lizard drops a Fire Gem.
Outside the tunnel on the left is Yellow Bug Pellet x3.
At the skeleton gate find a Large Soul of a Nameless Soldier and Black Bug Pellet x2.
Open the gate for an Ember beyond it.
In the tunnel back to the pillar room, Knight Slayer Tsorig invades if you are embered. Win or lose you get the My Thanks! gesture; killing him gives the Knight Slayer's Ring.
Before the bridge go right to Anri again and exhaust her dialogue.
Drop down left of Anri and follow the path to the boss.
Defeat High Lord Wolnir for the Soul of High Lord Wolnir.
If you missed it during the fight, the Grave Warden Pyromancy Tome is in the far left corner of the goblet room. Only Karla can read it.
