Departure to No-Man's Wharf
Fast-travel to Tower of Flame bonfire, continue ahead and go down the spiral staircase. After reaching the base of the stairs, search the corpse behind it to find a Monastery Charm. Defeat the two Old Knights here and follow the path straight ahead to find three corpses containing Human Effigy, Dark Troches, Soul of a Proud Knight, and Old Knight Halberd.
Enter the doorway in the middle and go downstairs. Take out the Old Knight hanging right outside the next doorway and another one along the corridor if you turn right. There's nothing of interest in the corridor to the left so ignore it for now. Continue along the path until you find a lift. Ride it down and follow the flooded tunnel.
Along the way, you'll find a small doorway guarded by an Old Knight. Defeat it and continue upstairs. Turn to the right to find a chest in an alcove at the end. Open it to get a Knight Armor Set. (Helm, Armor, Gauntlets and Leggings)
Backtrack to the flooded tunnel and continue along the main path until you reach another tunnel leading to a cavern. Follow the path and you'll find a bonfire called No-Man's Wharf. There's also an NPC named Lucatiel. Exhaust her dialogue during this conversation and she'll offer you assistance by allowing you to summon her on specific areas of the game. (Sinner's Rise, Iron Keep, No-man's Wharf, Black Gulch)
Continue along the path and you'll reach No-man's Wharf. Before going in, make sure you have at least one Pharros Lockstone in your possession.
