Here's the recap:SPOILER

Picked Pyromancer Class & Master Key, ran through Undead Asylum
Picked up the Homeward Bones at Firelink Shrine
Dashed through the Undead Burg, lit bonfire
Dashed through the enemies, picked up the Gold Pine Resin
Dashed through on to the Taurus Demon, used Gold Pine Resin to beat him
Talked to Solaire (could have skipped this)
Kicked ladder for shorcut.
Used Gold Pine Resin to cut off Hellkite Dragon's tail, obtained Drake Sword. Died by his breath attack. (could have gone better).

Dashed through Undead Parish, rolled underneath the big gate, saving time.
Lit bonfire near Andre and bought tower shield.
Killed the Tower Knight (could have skipped this).
Got held up by zombies on my way to the Gargoyles. Need better dodging.
Summoned Solaire, defeated Gargoyles & rang bell -> homeward bone back to Andre. Bought repair and upgrade boxes. Used shortcut back to Firelink Shrine.
Forgot to kill Lautrec (big mistake).

Dashed through Valley of Drakes and lit Blighttown Swamp bonfire. Summoned some players and killed Quelaag on my third or fourth try. This obviously took too long.
Rang bell. Visited Daughter of Chaos, joined covenant and upgraded pyromancy flame.
Obtained Gold Hemmed Set from Demon Ruins and defeated Ceaseless Discharge (smooth!)

Bought some Pyromancy from Quelana on the way back to Firelink.
Dashed on to Sen's Fortress. Skipped all treasure hunting except for the Lightning Spear and cleared Sen's Fortress. A big plus: I didn't die. The cons; I didn't get the flame stoneplate ring or the ring of steel protection. Both would've been useful later on.

Dashed through Anor Londo using Combustion to kill Painting Guardians. Wasted some time fighting one of the Gargoyles.
Lit the Darkmoon Tomb bonfire.
Died twice getting past the Silver Knight snipers. Used a riposte to succeed.
Lit the bonfire and summoned some players. Obtained Havel's Set, Occult Club and unlocked shortcut, skipped all else. Died twice fighting Ornstein and Smough, obviously losing some time.

Warped to Firelink, placed Lordvessel.
Dashed to Darkroot Garden, made a run for the Wolf Ring and Elite Knight Set.
Dashed through the forest on to Sif. Died 4-5 times, wasting a lot of time.
After defeating him I wanted to obtain the Divine Ember in preparation for the Catacombs. This was a bad idea, because eventually I just downgraded the occult club (found in Anor Londo) to a Divine Club +5. Wasted some time defeating the Moonlight Butterfly.

Warped to Firelink. Killed Petrus for his Humanity.

Dashed through Catacombs, skipping almost all treasure.
Lit bonfire halfway through.
Killed Patches.
Used the Vamos shortcut to get to Pinwheel quickly, making a Fire Claymore on the way.
Used homeward bone to make use of Pinwheel's souls.
Dashed to the Tomb of Giants. Died twice before finally reaching the bonfire. (wasted some time)
Beat Paladin Leeroy, used homeward bone to make use of souls.
Waited a while for summon signs, but none showed. Decided to take Nito on solo and succeeded. (could've been quicker, as I didn't use pyromancy)
Warped to Daughter of Chaos.

Dashed through Demon Ruins. Killed Demon Firesage and Centipede Demon (Solaire helped).
Dashed through Lost Izalith, lit bonfires along the way.
Ignored the pyromancer and invader Kirk.
Defeated Bed of Chaos in 4 tries. (could be quicker, quitting the game and reloading might help)

Warped to Anor Londo.
Dashed through Dukes Archives to the first Seath fight. Got cursed (fuuuuu).
Dashed on through the prison (while cursed) and onto the balcony bonfire.
Dashed through the Crystal Cave, wasted time defeating crab creatures for a purging stone. Didn't get one and actually got killed trying.
Dashed through for a second try, got a purging stone. Got owned by Seath.
Summoned some players, got owned by Seath again.
Summoned more players, got cursed by Seath and died. (fuuuuuuu)
Luckily I had another purging stone. Summoned more players and used up all my Humanity to boost curse resistance. Finally beat Seath. (took way too long)

Warped to Firelink.
Dashed through New Londo. Got killed twice on my way to Ingward. (time wasted) Obtained Fire Keeper Soul.
Warped to Daughter of Chaos for upgrade.
Dashed through New Londo, reached Ingward and drained.
Jumped down to face the Four Kings.
Equipped Havel's set and full pyromancy. Beat them with no Estus left.

Warped to Firelink, unlocked the Kiln. Fought the first Black Knight on every try in hope of a Black Knight sword (wasted some time).

Beat Gwyn on the 5th try. (could have gone smoother)


Long story short, my biggest time-wasters were Sif and Seath. Biggest mistakes were not killing Lautrec, not getting the Ring of Steel Protection and the useless trip to the Moonlight Butterfly. Tempted to try again...
