Crystal Cave

Across the invisible paths to Seath, then back up into the Archives and on to Rickert.

The Crystal Cave hangs over a long drop, and some of its walkways can't be seen. Falling snow settles on them, glowing messages often mark them, and a Prism Stone dropped ahead shows whether the floor is there (a chest of them waits under the secret-library stairs); an arrow fired ahead works too. The great Moonlight Butterflies perched around the cave leave you alone unless you come close or strike them. The boss lives at the bottom; afterwards the route climbs back into the Archives.

Humanity (first invisible path)Consumable
Location
Crystal Cave · First invisible path – From the Duke's Archives balcony bonfire, go back through the secret library, down the stairs its lever revealed and into the garden, then down the slope past two Crystal Golems into the cave. Past the first golem inside, the walkway bends in a Z: before its first corner, snow falls on empty air on the left. Walk that invisible path straight out to a corpse, then drop to the platform below to rejoin the walkway.
Requires
Summary
A Humanity at the end of the first invisible path.

Follow the walkway on past a perched Moonlight Butterfly to what looks like a dead-end cliff: snow and messages mark a second invisible path running straight ahead. A Golden Crystal Golem stands on the big crystal walkway off to the left as you reach it; shoot it so it comes to you on solid ground instead of fighting it on the narrow crystal. Cross the straight path, walking only where the snow lands, to the big crystal walkway, and follow that to its end.

Crystal Lizards x3 (Crystal Cave)NPC
Location
Crystal Cave · Lizard tunnel – At the end of the big crystal walkway, drop off its left side onto an invisible platform, then turn round at once: the lizards are in the tunnel behind you. Kill them before they vanish.
Requires
Summary
Three Crystal Lizards in a tunnel off an invisible platform. Each drops Twinkling Titanite; any that escape come back after a quit and reload.

Blue Titanite Chunk (second Golden Golem)Upgrade
Location
Crystal Cave · Below the lizard tunnel – From the Duke's Archives balcony bonfire, go back through the secret library, down its hidden stairs and across the garden into the cave; follow the crystal walkways down, cross the second invisible path (the straight one past the first golden golem) to the end of the big crystal walkway, and drop off its left side onto the invisible platform. A second Golden Crystal Golem stands on the crystal ledge below, and the chunk lies on a corpse beside it: step carefully off the platform's edge to reach it (the golem leaves you alone if you leave it alone). An invisible path from that ledge climbs back up to where the first golden golem stood; cross the big walkway again and drop back onto the platform.
Requires
Summary
Upgrade material for the Magic and Enchanted paths, beside a second Golden Crystal Golem.

Blue Titanite SlabUpgrade
Location
Crystal Cave · End of the winding invisible path – From the invisible platform at the end of the big crystal walkway, go through the lizards' tunnel to its far end, where an invisible path twists through sharp turns. Edge along it a step at a time, dropping Prism Stones (or firing arrows ahead) to find the floor; it ends on a crystal beam with the slab on a corpse. Come back the same way, following the stones you dropped.
Requires
Summary
The slab that finishes a weapon on the Magic path. It is one of the nine slabs the ten upgrade trophies need this run: keep it for the Magic Weapon and never spend it on anything else.

Soul of a Hero (Crystal Cave)Consumable
Location
Crystal Cave · Ledge before the shell cave – Back through the tunnel to the invisible platform, take the straight invisible path that carries on ahead (another butterfly sits on the left; ignore it). Where it reaches solid ground, before the cave in front of you, turn left to a corpse. Taking the soul may wake the butterfly, so dash into the cave afterwards.
Requires
Summary
A soul item on a ledge just before Seath's cave.

Moonlight Greatsword (tail cut)Hidden spoiler – activate to revealWeaponMissablePoint of no returnMinor spoiler
Location
Crystal Cave · Seath's chamber – From the slab, go back through the lizards' tunnel to the invisible platform and follow the straight invisible path ahead to solid ground; the cave beyond leads to Seath's chamber. During the fight, strike the very tip of his tail until it falls off, then pick the sword up from it. The best moment is just after the Primordial Crystal breaks, while he reels.
Why you can lose it
Cut Seath's tail before he dies; once he is dead the sword is gone for this run.
Point of no return
Killing Seath the Scaleless in the Crystal Cave.
Requires
Summary
A rare weapon for Knight's Honor, cut from Seath's tail. There is one tail, so one chance each run.
Sources

Before you kill Seath

His death closes, for this run: the Moonlight Greatsword (cut the tail first); and, if Logan is still in his cell at the foot of the prison tower, Logan's library shop with Homing Crystal Soulmass, Crystal Magic Weapon and Crystal Soul Spear may never open (free him first).

Seath the ScalelessHidden spoiler – activate to revealBossMinor spoiler
Location
Crystal Cave · Seath's chamber – Man-Eater Shells crowd the cave before his chamber: on the first visit there is no fog gate and they follow you in, so pull them one at a time and kill them first. In the chamber, break the tall crystal at the back before anything else, then attack from his side and run clear of his slams. His breath builds curse; the Bloodshield from the Painted World helps resist it.
Requires
Summary
The lord of the Crystal Cave. Nothing hurts him until the Primordial Crystal at the back of his chamber is broken. He leaves a Lord Soul for the Lordvessel.

Logan: finish his library talks (Seath dead, every spell bought)Hidden spoiler – activate to revealQuest stepMinor spoiler
Location
The Duke's Archives · Secret library, small room – Warp to the Duke's Archives balcony bonfire and go to Logan in the small room of the secret library. Buy whatever is still on his list, then talk to him until he no longer seems to know you, and pass a loading screen (quit and reload, or use a Homeward Bone).
Requires
Summary
With Seath dead and Logan's stock bought out, talking to him moves his story on to one last meeting.

Location
The Duke's Archives · Seath's first room – From the Duke's Archives balcony bonfire, take the shortcut on the ground floor of the bonfire's room into the first library room, climb the grand staircase to the inside balcony and ride the lever lift at its far end, then go through the crystal tunnel and up the crystal stairs to the room where Seath first met you. With Seath dead the room is safe from him. A fight against a sorcerer waits there, so close in between casts. If you die here, you wake at the prison cell bonfire.
Requires
Summary
A last meeting in that room, required: it ends with White Dragon Breath, a sorcery nobody else has.

Wisdom of a SageHidden spoiler – activate to revealAchievementMissablePoint of no returnMinor spoiler
Location
The Duke's Archives · Seath's first room – Pops when White Dragon Breath is picked up, if every other sorcery is already yours: the ones from Griggs, Logan, Dusk (or Elizabeth in Oolacile) and Ingward, plus Hush, Remedy, Great Magic Weapon and Strong Magic Shield from the world. If it doesn't, buy whatever is missing from those sellers.
Why you can lose it
Several sorceries are sold only by Griggs, Logan, Dusk and Ingward: never attack them before their stock is bought.
Point of no return
Beating Gwyn, Lord of Cinder, then lighting the bonfire or walking out of his arena: either ends this run at once and starts the next one.
Requires
Summary
The trophy for owning every sorcery of the base game (the Artorias of the Abyss sorceries don't count). White Dragon Breath is normally the last one.

Blue Titanite Chunks (farm, if short)Quest step
Location
Crystal Cave · Archives garden and cave walkways – From the Duke's Archives balcony bonfire, go back through the secret library and down its hidden stairs into the garden. The Crystal Golems there can drop Blue Titanite Chunks, and so can the Moonlight Butterflies along the first Crystal Cave walkways below. Both come back whenever you rest: clear the garden, go on to the first butterfly, then use a Homeward Bone (or walk) back to the balcony bonfire, rest and go again. Human form and the Covetous Gold Serpent Ring help.
Requires
Summary
The Magic Weapon needs seven Blue Titanite Chunks. Count yours now, while the garden is close: if you have fewer, farm the rest before you leave the Archives.

Sieglinde: answer Yes again at FirelinkHidden spoiler – activate to revealQuest stepMissablePoint of no returnMinor spoiler
Location
Firelink Shrine · By the bonfire – Warp to the Firelink Shrine bonfire (it can be warped to even if its fire is out). If Sieglinde stands near the bonfire, talk to her until she asks whether you have seen her father, and answer Yes again; she then sets off once more.
Why you can lose it
Answer Yes when she asks about her father; No may end her story for this run.
Point of no return
Beating Gwyn, Lord of Cinder, then lighting the bonfire or walking out of his arena: either ends this run at once and starts the next one.
Requires
Summary
Required: she asks about her father once more at the shrine, and a Yes keeps her story going toward the Titanite Slab the upgrade trophies need.

Give Rickert the Large Magic EmberQuest stepMissablePoint of no return
Location
New Londo Ruins · Rickert's cell – From the Firelink Shrine bonfire, go back to Rickert's cell: take the stairs down past the Fire Keeper's cell to the lift and ride it down, walk down the stairs and through the doorway on the left, then go right past the door to the Valley of Drakes to the Hollow lying on his side and take the stairs down on his left. Rickert sits behind bars at the bottom; give him the ember when he asks.
Why you can lose it
Never hit Rickert: long weapons and wide spells reach him through the bars, and an angry or dead Rickert takes no embers and ascends nothing for the rest of the run.
Point of no return
Beating Gwyn, Lord of Cinder, then lighting the bonfire or walking out of his arena: either ends this run at once and starts the next one.
Requires
Summary
With the ember, Rickert can reinforce Magic weapons all the way to +10.

Magic WeaponAchievement
Location
New Londo Ruins · Rickert's cell – At Rickert, ascend a Normal weapon at +5 to Magic, then reinforce it to +10. From an unupgraded weapon the whole path takes nine Titanite Shards, ten Green Titanite Shards (both sold without limit), seven Blue Titanite Chunks and the Blue Titanite Slab. The fixed chunks are two in the Great Hollow, the Darkroot Basin Black Knight's and the Archives and Crystal Cave ones (plus perhaps one from the Archives Crystal Lizard); the farm above makes up the rest.
Requires
Summary
The trophy for a weapon at Magic +10. The Enchanted path needs its own chunks and the second Blue slab later, so spend only what this needs.

To leave, ride the lift back up to Firelink Shrine and warp from its bonfire if its fire burns again. If it is still out, take the elevator up into the Undead Parish and warp from the Parish bonfire.

About this guide

Three runs. The first is the full walk: every area, Artorias of the Abyss, every covenant, all four spell collections and the ten weapon-upgrade trophies, ending at the Kiln. New Game+ is a leaner run for the other ending and the last miracle. A short third run stops once the last Soul of Sif has been turned into a weapon. A few trophy weapons and covenant offerings only come from enemies, so expect some farming.
