Key takeaways
- Reach it through Ellac River From Gravesite Plain, travel through Ellac River Cave and Ellac River Downstream, then follow the river south.
- Find the Southern Shore map fragment early It lies close to the first Cerulean Coast approach and reveals the southern part of the DLC map.
- The region has several separate destinations Cerulean Coast West, Cerulean Coast Cross, the Southern Nameless Mausoleum, the Stone Coffin Fissure entrance and the route towards the Finger Ruins of Rhia.
- The most important rewards are spread widely Demi-Human Queen Marigga drops the Star-Lined Sword, the Ghostflame Dragon drops a Dragon Heart and Somber Ancient Dragon Smithing Stone, and the Southern Nameless Mausoleum contains the Dancer’s Set and Dancing Blade of Ranah.
- The Stone Coffin Fissure is a connected legacy-style dungeon, not just a coastal landmark: Its final boss is the Putrescent Knight, and the area is central to Thiollier and St. Trina’s questline.
- The coast has no normal settlement or conventional merchant district Most named structures are ruins, memorial markers, boss arenas, Sites of Grace or decorative remains.
About this guide
Scope: This guide covers the Cerulean Coast region in Elden Ring: Shadow of the Erdtree, including its named overworld sections, the Southern Nameless Mausoleum and the Stone Coffin Fissure entrance. It treats Charo’s Hidden Grave, the Finger Ruins of Rhia and the Jagged Peak as neighbouring or connected areas rather than silently folding them into the main coast. Spoilers: This guide includes optional bosses, Miquella’s Crosses, St. Trina’s questline, the Stone Coffin Fissure and the Putrescent Knight.
Overview
The Cerulean Coast is a large southern region of the Land of Shadow, reached from the lower Ellac River in Gravesite Plain. Its defining landscape is a blue-flowered shoreline scattered with enormous stone coffin-ships, dead trees, rocky gorges and shallow pools. The region is visually peaceful but contains several difficult optional encounters, including the Ghostflame Dragon, Demi-Human Queen Marigga and the Dancer of Ranah. Its southern fissure also leads into the Stone Coffin Fissure, an important side dungeon connected to Thiollier and St. Trina.
The coast is not simply the beach surrounding the Cerulean Coast Site of Grace. It is a broad southern landmass with several distinct navigation spaces: the western coast and gorge, the central flower fields, the eastern approach to the Finger Ruins of Rhia, the island containing the Southern Nameless Mausoleum, and the chasm leading to the Stone Coffin Fissure. Some maps and guides group connected entrances differently, so this guide separates the places by their in-game identity and function rather than treating every nearby blue-coloured area as one undifferentiated zone.
The region is optional in the main DLC route, but it contains valuable upgrade materials, a unique weapon, a unique armour set, a remembrance boss and major progress for Thiollier’s story.
Named geographic sections
What is and is not part of the region
The game’s map presentation can make these boundaries appear less formal than those of a legacy dungeon. The distinction matters because bosses, quest steps and collectible routes are not all located in the same subarea.
---
What is and is not part of the region
| Place | Relationship to Cerulean Coast |
|---|---|
| Cerulean Coast West | Western named section of the coast |
| Cerulean Coast Cross | Eastern coastal section containing a Miquella’s Cross |
| Southern Nameless Mausoleum | Island destination reached from the coast |
| Stone Coffin Fissure | Connected dungeon reached from the southern chasm |
| Finger Ruins of Rhia | Neighbouring eastern area, reached from the coast |
| Charo’s Hidden Grave | Separate southern region beyond the coast |
| Jagged Peak | Separate mountainous region reached through the southern areas |
Reaching the Cerulean Coast
The normal route begins in Gravesite Plain.
The route is deliberately easy to miss because it does not begin at a large gate or obvious road. From the Gravesite Plain side, look for the river system south-east of Castle Ensis. The poison-filled lowlands and cave route eventually open into the blue coastal landscape.
A guide covering the area lists the Southern Shore map fragment, Grave Glovewort, the Ghostflame Dragon, Demi-Human Queen Marigga, the Southern Nameless Mausoleum and the Stone Coffin Fissure among the principal coastal objectives.
Reaching the Cerulean Coast: steps
- 01Travel to Ellac River Cave.
- 02Continue through the river route to Ellac River Downstream.
- 03Follow the river south.
- 04Pass beneath the rocky approach and enter the Cerulean Coast.
- 05Activate the first coastal Site of Grace before exploring the shoreline.
Recommended first route
This route avoids repeatedly crossing the entire region. It also leaves the most quest-sensitive part, the Stone Coffin Fissure, until the player has encountered Thiollier and is ready to advance his story.
---
The named checkpoints in and around the coast are useful because the region has long stretches of open ground and several field bosses.
A practical first sweep is
- 01Activate Cerulean Coast.
- 02Collect the Southern Shore map fragment.
- 03Explore west to Cerulean Coast West.
- 04Search the western gorge and small cave.
- 05Defeat or bypass Demi-Human Queen Marigga.
- 06Return east and investigate the main flower fields.
- 07Defeat the Ghostflame Dragon when prepared.
- 08Travel east to Cerulean Coast Cross.
- 09Collect the Miquella’s Cross and Scadutree Fragment.
- 10Visit the Southern Nameless Mausoleum.
- 11Descend into The Fissure when ready for the Stone Coffin Fissure.
- 12Continue east only when prepared to enter the Finger Ruins of Rhia.
Cerulean Coast
The primary arrival Site of Grace. Use it as the central return point for the Ghostflame Dragon, the southern flower fields and the western and eastern branches.
Cerulean Coast West
This checkpoint serves the western section. It is particularly useful for reaching the western gorge, the small cave containing a Scadutree Fragment and the beach where Demi-Human Queen Marigga appears.
Cerulean Coast Cross
This grace is near a Miquella’s Cross and a Scadutree Fragment. It is the most useful checkpoint for the eastern coastal route and the descent towards the Stone Coffin Fissure.
Southern Nameless Mausoleum
This Site of Grace is on the island west of the main coast. It is the checkpoint immediately outside the Dancer of Ranah encounter.
The Fissure
This grace sits in the chasm at the southern edge of the coast. It marks the transition from the open coastal region to the Stone Coffin Fissure dungeon.
---
The coffin-ships
The enormous stone coffins are the visual signature of the region. They appear to be vessels that have washed ashore from beyond the Lands Between, reinforcing the coast’s association with death, burial and distant worlds.
In practical terms, the coffins are platforms. Their upper surfaces hold Grave Glovewort, Great Grave Glovewort and other collectibles. Some can be reached by climbing natural rock formations; others require jumping from adjacent coffins or using Torrent.
Blue flower fields
The flower-covered coast is largely open terrain rather than a settlement. The flowers make enemies difficult to see at a distance, particularly in the low ground around the Ghostflame Dragon. The open spaces also allow Torrent to create distance from field bosses, though several enemies can pursue farther than expected.
Western gorge
The western gorge contains a demi-human encounter, a Starlight Shard and the Spirit Sword. It is easy to overlook because the route bends away from the main beach.
Southern Nameless Mausoleum
The mausoleum stands on an island separated from the main coastal landmass. It is a small but important boss location. The Dancer of Ranah waits inside, and the encounter provides one of the region’s distinctive armour and weapon rewards.
The Fissure
The fissure is a dramatic break in the southern landscape. A descent through it leads to the Stone Coffin Fissure. The entrance is not merely a scenic drop: it is a progression route into one of the DLC’s most important optional story areas.
Finger Ruins of Rhia
The Finger Ruins of Rhia lie to the east of the coastal region. They are identifiable by their enormous finger-like structures and unusual enemies. They are associated with the southern finger-related objective and should not be confused with the Finger Ruins of Dheo or the Finger Ruins of Miyr elsewhere in the DLC.
---
The Cerulean Coast has no ordinary town population. It is primarily wilderness, ruins and boss territory.
Thiollier
Thiollier is the most important character associated with the region, although his early appearances are elsewhere. His quest eventually leads into the Stone Coffin Fissure and the domain of St. Trina.
Progressing his quest requires careful attention to dialogue, inventory items and the changing state of the surrounding NPC questlines. The Stone Coffin Fissure is not just a combat detour. It is where Thiollier’s devotion to St. Trina becomes central to his story.
St. Trina
St. Trina is encountered in the depths of the Stone Coffin Fissure. This section contains major story revelations and a sequence of interactions that can affect Thiollier’s later involvement.
The encounter is deliberately obscure. St. Trina is not presented as a conventional town NPC, and the player must understand that repeated interaction is part of the quest rather than treating the first encounter as a completed conversation.
Dancer of Ranah
Dancer of Ranah is the boss of the Southern Nameless Mausoleum. She is a story-associated figure rather than a resident of the coast. Her defeated rewards include the Dancing Blade of Ranah and the Dancer’s Set.
Demi-Human Queen Marigga
Marigga is a named field boss in the western coastal area. She is encountered near the beach and provides the Star-Lined Sword on defeat.
Ordinary inhabitants
No friendly settlement, merchant camp or conventional coastal community has been verified within the region. The apparent structures are primarily mausoleum architecture, memorial features, natural rock formations and dungeon entrances. Do not assume a decorative building is enterable or functional.
---
Boss directory
The first three are encountered in or immediately around the open coastal area. Putrescent Knight is located in the Stone Coffin Fissure, which is accessed from the coast but functions as a distinct dungeon and quest area. Interactive boss directories commonly classify Cerulean Coast as containing four boss encounters when this connected dungeon content is included.
Boss directory
Ghostflame Dragon
The Ghostflame Dragon occupies the open coastal ground south of the main arrival area. It is a large field boss with wide-reaching attacks and strong control over the space immediately around its body.
The fight is easier on horseback if the player uses the open ground to circle the dragon and disengage from its area attacks. Ranged builds can exploit distance, but the dragon’s movement and ghostflame attacks make careless stationary casting dangerous.
These rewards make the encounter worthwhile even for players who are not following a completionist route. The Ghostflame Dragon is also one of the clearest examples of the coast’s death-themed visual language.
Demi-Human Queen Marigga
Marigga is found on the western beach. The route is easiest from the western coastal grace, travelling through the gorge and then towards the beach.
The Star-Lined Sword is a unique weapon and one of the most important permanent rewards in the western part of the region. A coastal walkthrough places Marigga on the north-western beach and identifies the sword as her reward.
Defeating Marigga awards
Dancer of Ranah
The Dancer of Ranah is fought in the Southern Nameless Mausoleum. The mausoleum lies on an island west of the main coastline, and the island is reached by following the coastal route and using the rocky and coffin-like formations as a crossing.
The fight is fast and close-range. Dancer of Ranah uses sweeping attacks and can punish players who remain locked on at poor range. Light weapons, status effects and summons can all be useful, but the confined arena leaves less room for Torrent-based tactics than the Ghostflame Dragon encounter.
The reward set includes
Putrescent Knight
Putrescent Knight is the remembrance boss at the bottom of the Stone Coffin Fissure. The dungeon is reached by descending through The Fissure at the southern edge of the coast.
This fight is relevant to both exploration and quest progression. It is also one of the DLC’s major optional remembrance encounters. Players should consider delaying the final approach until they have checked Thiollier’s current dialogue and inventory requirements.
---
The Cerulean Coast contains a large quantity of upgrade materials. Many are placed on the stone coffins, making a vertical sweep essential.
Major unique rewards
The regional item list also includes Lost Ashes of War, Grave Keeper’s Cookbook (1), St. Trina Disciple’s Cookbooks (1) and (2), a Hefty Cracked Pot and multiple Grave Glovewort and Great Grave Glovewort pickups.
Major unique rewards
| Item | Location or source | Notes |
|---|---|---|
| Star-Lined Sword | Demi-Human Queen Marigga | Unique weapon |
| Dancing Blade of Ranah | Dancer of Ranah | Unique weapon |
| Dancer’s Set | Dancer of Ranah | Armour set |
| Perfumed Oil of Ranah | Island near the Southern Nameless Mausoleum | Found before or around the mausoleum route |
| Spirit Sword | Western gorge | Fixed pickup |
| Somber Ancient Dragon Smithing Stone | Ghostflame Dragon | Fixed boss reward |
| Dragon Heart | Ghostflame Dragon | Fixed boss reward |
| Scadutree Fragment | Coastal cave and Cerulean Coast Cross area | Fixed collectibles |
| Southern Shore | Map fragment | Reveals the region |
| Miquella’s Cross | Cerulean Coast Cross | Fixed landmark collectible |
Upgrade materials and fixed pickups
Verified named pickups associated with the coastal sweep include:
The exact number of glovewort pickups depends on whether a guide groups the connected coffin ledges under Cerulean Coast or under an adjacent named section. The important practical point is that the region contains several fixed glovewort placements, especially on coffin-ships near Cerulean Coast Cross and the western approach.
Collectible route
---
The Cerulean Coast Cross is in the eastern coastal section. It is accompanied by:
These are fixed, non-random collectibles. The cross also contributes to the wider Miquella’s Cross trail, allowing players to track the locations where Miquella’s journey is marked across the Land of Shadow.
The eastern cross is easy to miss if the player follows the coastline directly towards the Finger Ruins of Rhia. Use the Cerulean Coast Cross Site of Grace as the navigation anchor, then search the nearby beach and coffin formations before leaving the area.
---
The Stone Coffin Fissure is the most consequential connected area.
A useful acquisition order is
- 01Take the Southern Shore map fragment.
- 02Search the coffins near the first coastal grace for Grave Glovewort.
- 03Explore the western swamp and tree area for Lost Ashes of War and Grave Keeper’s Cookbook (1).
- 04Enter the western gorge for the Starlight Shard and Spirit Sword.
- 05Enter the small cave north-west of the gorge for a Scadutree Fragment.
- 06Defeat Marigga and collect the Star-Lined Sword.
- 07Search the coffin ledges around the central coast.
- 08Collect the Perfumed Oil of Ranah on the mausoleum island.
- 09Defeat the Ghostflame Dragon for its fixed rewards.
- 10Travel east to Cerulean Coast Cross for the Miquella’s Cross and Scadutree Fragment.
- 11Search the nearby coffins for additional glovewort.
- 12Pick up the Hefty Cracked Pot near the troll.
- 13Collect St. Trina Disciple’s Cookbook (2) near the south-eastern cliff.
- 14Descend to The Fissure.
Access
From the eastern or central Cerulean Coast, travel towards the southern chasm. Descend carefully until reaching The Fissure Site of Grace. Continue through the dungeon, following the stone platforms and coffin-like architecture deeper underground.
The entrance is associated with a Miquella-related seal. Progression through the relevant DLC story state is required before the full route becomes available. A commonly reported progression condition is that the player must reach the point where Miquella’s Great Rune is discarded. This is a progression-state issue rather than a combat requirement.
Why it matters
Do not rush into the final boss if you are following Thiollier’s quest. Exhaust dialogue, check the relevant inventory items and rest or reload when the quest requires a state change.
The Stone Coffin Fissure contains
Putrescent Knight and rewards
After descending through the fissure, the player reaches the Putrescent Knight’s arena. The encounter awards a Remembrance that can be exchanged through the DLC’s remembrance systems for powerful rewards associated with the boss.
The fight includes a large mounted or paired enemy presentation, strong physical attacks and a blue-white ghostflame aesthetic. The arena gives room to manoeuvre, but the boss’s movement can make healing and spell preparation unsafe if the player remains too close.
---
Thiollier and St. Trina
The Cerulean Coast is one of the main locations for the latter part of Thiollier’s questline.
Because Shadow of the Erdtree contains several interlocking NPC questlines, the exact availability of dialogue can change after major story events. The coast itself does not provide a simple quest log, so players should keep track of which NPCs they have met and which items they have been asked to deliver.
A safe general procedure is
- 01Meet Thiollier during his earlier appearances outside the coast.
- 02Progress his dialogue and related NPC events before entering the final part of the Stone Coffin Fissure.
- 03Reach St. Trina in the fissure.
- 04Interact with St. Trina as required rather than assuming the first interaction completes the sequence.
- 05Return to Thiollier or reload the area when dialogue changes.
- 06Defeat Putrescent Knight when the quest route directs you there.
- 07Check for summon signs and later quest appearances before completing major late-DLC events.
Dancer of Ranah
The encounter is not dependent on completing a conventional NPC quest.
This is a self-contained optional activity
- 01Reach the island west of the coast.
- 02Activate the Southern Nameless Mausoleum Site of Grace.
- 03Enter the mausoleum.
- 04Defeat Dancer of Ranah.
- 05Collect the weapon and armour rewards.
Finger Ruins of Rhia
The Finger Ruins of Rhia are the main eastward activity from the coast. They form part of the DLC’s finger-related exploration and should be treated as a separate destination rather than a minor landmark within the blue flower fields.
If you are following the wider finger-related objectives, visit the ruins after clearing the Cerulean Coast Cross area. This reduces backtracking and ensures that the map and eastern Sites of Grace are already available.
---
Poison and rot terrain
Some low-lying areas contain hazardous water and swamp-like terrain. Avoid standing in contaminated ground during fights, especially when facing nearby groups. Use the edge of the terrain to draw enemies out rather than fighting while the status meter rises.
Coffin jumps
Many collectibles are placed on coffins that are technically reachable but visually disconnected. Approach from the highest nearby rock, use Torrent for controlled jumps and do not assume that every coffin requires a hidden route. Some are simply platforming challenges.
Hidden cave beneath the dead tree
A cave beneath a dead tree on the southern side of the coastal cliffs leads to a coffin route and additional upgrade materials. It is an easy omission because the entrance is below the apparent path rather than at eye level.
Mausoleum island
The island containing the Southern Nameless Mausoleum can look inaccessible from the main beach. Follow the rocky route and coffin formations rather than attempting to swim or jump directly across the water.
Missable progression states
The region’s fixed pickups and bosses are generally available throughout a normal playthrough, but NPC dialogue and summon opportunities can be affected by wider DLC progression. The most important caution concerns Thiollier, St. Trina and the Stone Coffin Fissure. Check dialogue before defeating major story bosses or advancing the central DLC plot.

Fissure

Is Charo’s Hidden Grave part of the Cerulean Coast?
No. It is a neighbouring southern region. The two areas share visual themes and nearby routes, but Charo’s Hidden Grave should be listed separately when documenting locations, bosses and collectibles.
Is the Stone Coffin Fissure part of the Cerulean Coast?
It is a connected dungeon reached directly from the coast, but it has a distinct name, internal map structure, boss and quest role. For navigation, treat it as a child destination of the coastal route rather than as ordinary overworld terrain.
Can I reach the coast before defeating major DLC bosses?
Yes. The route from Gravesite Plain is available early in the DLC, although the Stone Coffin Fissure has a progression condition connected to Miquella’s Great Rune and wider story advancement.
What is the best reason to visit the coast?
The region combines several high-value rewards: the Star-Lined Sword, Dancing Blade of Ranah, Dancer’s Set, a Somber Ancient Dragon Smithing Stone, Scadutree Fragments, upgrade materials and access to the Putrescent Knight and St. Trina questline.
Is there a merchant or shop on the Cerulean Coast?
No functional merchant service has been verified as part of the region. The coast is wilderness and dungeon territory rather than a settlement. Decorative or ruined structures should not be treated as businesses without an explicit merchant interaction.
Which boss should I fight first?
Demi-Human Queen Marigga is usually the most straightforward early target because the arena is open and the reward is immediately useful. The Ghostflame Dragon is also accessible early but requires more attention to large area attacks. Dancer of Ranah is a confined melee encounter, while Putrescent Knight should be approached after preparing for the Stone Coffin Fissure and checking Thiollier’s quest state.
---
This guide is based on available regional walkthroughs, location summaries and boss directories. The principal regional walkthrough verifies the access route, Southern Shore map fragment, named Sites of Grace, major boss rewards, Miquella’s Cross, Scadutree Fragment, cookbooks, Spirit Sword, Perfumed Oil of Ranah and the Stone Coffin Fissure route. The broader location summary identifies the Cerulean Coast as a Shadow of the Erdtree subregion and describes its blue-flower coast, coffin-ships, Finger Ruins of Rhia connection and southern fissure.
Some community and interactive-map sources use different boundary conventions for Cerulean Coast, particularly concerning the Finger Ruins of Rhia, the Southern Nameless Mausoleum and the Stone Coffin Fissure. For that reason, this guide preserves them as separately named connected destinations rather than claiming that every source uses one identical hierarchy.
A fully item-by-item coordinate audit would require a dedicated interactive map or game-data extraction pass. The directory above includes the verified named entries found in the accessible sources, but it should not be read as a claim that every individual crafting material, ammunition pickup, random enemy drop or unmarked plant has been exhaustively catalogued.
