Elden Ring: Thiollier Questline Complete Walkthrough
This guide will walk you through Thiollier's questline, detailing where to find him, the choices you'll face, and the rewards you'll receive.
Finding Thiollier
Thiollier can first be encountered near the Rotten Grove in the Poisoned Wastes, a new area introduced in the DLC. Here's how to locate him:
Starting Location – The Rotten Grove:
Travel to the Poisoned Wastes, accessible after defeating the Putrid Sentinel in the Shadow of the Erdtree expansion. You'll find Thiollier near a ruined chapel, surrounded by venomous plants.
First Interaction:
When you meet Thiollier, he'll express his devotion to St. Trina and hint at a brewing conflict involving his former master. Exhaust his dialogue to begin the questline. He'll give you the Venomous Insignia, an item that marks your progress in his storyline.
Questline Steps
Thiollier's quest unfolds over several stages, intertwining exploration, combat, and moral choices.
Step 1: Cleansing the Grove
Thiollier asks you to eliminate the Rotting Guardian, a mini-boss corrupting the Poisoned Wastes.
Boss Location: The Rotting Guardian resides in the southern part of the Poisoned Wastes. It's a challenging foe with powerful poison attacks, so bring items like Preserving Boluses or the Immunity Talisman to counter the effects.
Reward: Upon defeating the Rotting Guardian, return to Thiollier for 10,000 Elden Ring Runes and the Toxic Bloom, a crafting material exclusive to his questline.
Step 2: The Shrine of St. Trina
Thiollier requests your aid in reaching the Shrine of St. Trina, located in the Dreaming Glade.
Journey to the Shrine: The Dreaming Glade is a maze-like area filled with spectral enemies and environmental hazards. Equip a weapon imbued with Holy damage to deal with the spirits effectively.
Key Decision: At the shrine, you'll encounter a sealed artifact called the Trina's Vial. Thiollier asks you to give it to him, but you can choose to keep it instead.
Outcomes of the Decision:
If You Give Thiollier the Vial: He becomes stronger and offers a new poison-based incantation, Venomous Sleep, as a reward.
If You Keep the Vial: Thiollier is enraged but continues his questline. You'll receive a fragment of Elden Ring Runes and can use the vial to unlock a secret area in the Dreaming Glade.
Step 3: Confrontation with Thiollier's Master
Thiollier's ultimate goal is to confront his former mentor, Serpentmaster Kael, who betrayed St. Trina.
Boss Fight – Serpentmaster Kael: This battle takes place in the Chamber of Venom, a toxic-filled arena. Kael wields devastating serpent-themed attacks and summons venomous minions.
Allies or Foes: If you gave Thiollier the vial, he fights alongside you. If you kept it, he will attack you after the battle concludes.
Rewards and Outcomes
Depending on your choices, completing Thiollier's questline can lead to different rewards:
If Thiollier Survives:
St. Trina's Blessing: A talisman that enhances resistance to poison and sleep effects.
Venomous Sleep: A unique incantation that causes enemies to fall asleep while inflicting poison damage over time.
A significant rune reward (20,000 Elden Ring Runes).
If Thiollier Dies:
Trina's Vial (Enhanced): An upgraded version of the artifact that can be used to unlock rare Elden Ring Items scattered across the Dreaming Glade.
A smaller rune reward (10,000 Elden Ring Runes).
Tips for Completing Thiollier's Questline
Stock Up on Poison Resistance:
Many areas in this questline feature poison or venom effects. Equip gear that increases immunity and carry items like Preserving Boluses or Antidotes.
Balance Moral Choices:
Your decisions throughout the questline affect not only the rewards but also Thiollier's attitude. Weigh the benefits of keeping certain items versus maintaining his trust.
Upgrade Weapons and Summons:
Battles against the Rotting Guardian and Serpentmaster Kael are challenging. Ensure your weapons are upgraded and consider using Spirit Ashes to gain an advantage.
