Elden Ring Shadow of the Erdtree: Thiollier Quest Guide
In a land teeming with rot, ruin, and betrayal, even the most reclusive poisoner might offer an unexpected dose of truth.
Introduction
In Shadow of the Erdtree, the Tarnished finds rare moments of companionship amid the ever-present violence of the Lands of Shadow. Among these unlikely allies is Thiollier, a soft-spoken poison specialist whose devotion to St. Trina runs disturbingly deep. His questline is quiet, eerie, and easy to miss- but it leads to one of the DLC's most surreal encounters and a rare late-game summon.
This guide walks you through Thiollier's entire questline, including where to find him, key decisions, and how to avoid getting locked out of his rewards.
Quick Quest Summary
·Speak to Thiollier at Pillar Path Cross, southeast of Castle Ensis.
·Talk to Moore to get the Black Syrup, and give it to Thiollier.
·After the Shattering of Miquella's Rune, Thiollier will move south.
·Travel to Cerulean Coast and explore the Stone Coffin Fissure.
·Summon Thiollier against the Putrescent Knight, defeat it, and meet St. Trina.
·Drink her nectar six times to receive all of her dialogue.
·Try telling Thiollier the truth- twice- until he invades.
·Defeat him to earn the St. Trina's Smile talisman.
·Complete this before burning the Sealing Tree to unlock him as a late-game summon.
Step 1: Finding Thiollier (Pillar Path Cross)
Thiollier can first be found at Pillar Path Cross, southeast of Castle Ensis. He has Elden Ring Items for sale, including:
·Deadly Poison Perfume Bottle
·Thiollier's Concoction (after progressing his story)
·Be sure to speak with him multiple times.
Then, head to the Main Gate Cross and talk to Moore, who gives you the strange Elden Ring Items: Black Syrup. Give this to Thiollier, unlocking Thiollier's Concoction- a consumable that kills you.
Optional: Dragon Priestess Choice
Before facing Bayle the Dread, you can give Thiollier's Concoction to the Dragon Priestess at the Grand Altar of Dragon Communion. This will determine your reward after Bayle's death:
·Give the Concoction: Receive Ancient Dragon Florissax Spirit Ashes
·Don't give it: Receive Priestess Heart and Flowerstone Gavel
·Note: If you consume the concoction yourself, you can buy another from Thiollier for 30,000 Elden Ring Runes after resting.
Step 2: Progressing the Quest (Post-Shattering)
Thiollier's quest doesn't move forward until Miquella's Rune shatters, which occurs after going east past Bonny Village (itself east of Moorth Ruins). Speak with him again. He's now distraught and hints at heading south. At this point, Thiollier will relocate to the Stone Coffin Fissure under one of the following conditions:
·You discover St. Trina's location
·You rest at a grace inside the Fissure
·You burn the Sealing Tree in Shadow Keep
Step 3: Finding the Stone Coffin Fissure
Travel to the southernmost edge of the Cerulean Coast. You'll find a cavern entrance previously sealed by Miquella, now open. Inside, prepare for a dangerous descent filled with:
·Lookout Stones firing magical lasers
·Gravebirds
·Spectral Misbegotten
Take out the Gravebirds first, then carefully dodge or strike down the Lookout Stones. Eventually, you'll reach the Fissure Depths Site of Grace surrounded by sleeping creatures.
Jump from the statue head nearby to enter the Putrescent Knight's arena.
Step 4: Boss- The Putrescent Knight
Inside the arena, you'll see a summon sign for Thiollier. Use it- his poison damage is surprisingly effective in this fight. After defeating the boss:
·Rest in the grace
·Enter the chamber ahead to find St. Trina and Thiollier
Step 5: The Nectar of St. Trina
Speak to Thiollier to exhaust his dialogue, then interact with St. Trina and choose to imbibe her nectar. You will die. This is normal. Do this six times total:
·After the third time, she begins speaking.
·After the sixth, she tells you to kill Miquella.
Return to Thiollier and try to relay her message. He'll refuse to listen. On your second attempt, he will invade you.
Step 6: Defeating Thiollier and Finishing the Quest
After the invasion:
·Defeat Thiollier to earn the St. Trina's Smile talisman(Boosts attack power near Sleep-afflicted enemies)
·He'll remain silently kneeling beside St. Trina afterward
Don't delay this step. If you burn the Sealing Tree before doing it, Thiollier may disappear, and you'll miss the talisman and his summon.
Bonus: Thiollier as a Summon
If you complete Thiollier's full quest before burning the Sealing Tree, he becomes a summonable ally for one of the final boss encounters, alongside other Miquella's followers.
Conclusion
Thiollier's tale is one of twisted devotion and tragic obsession- an unforgettable thread in Shadow of the Erdtree's dark tapestry. From humble merchant to reluctant adversary, he offers players unique gear, powerful St. Trina.
Just be sure to finish his quest before you fan the flames.
