Note: Thiollier's questline is directly tied to the questlines of St. Trina and Moore.

1. Speak to Thiollier at the Pillar Path Cross

You can find Thiollier near the Pillar Path Cross Site of Grace. To reach Thiollier, head southeast from the Castle Front Site of Grace near Castle Ensis.

You may exhaust Thiollier's dialogue to unlock his shop. His questline progresses after you break Miquella's Seal.

2. Obtain Thiollier's Concoction

You can obtain Thiollier's Concoction by delivering Moore's Black Syrup to Thiollier. Afterward, speak to Thiollier and ask about the Black Syrup to receive Thiollier's concoction.

1. Speak to Moore at the Main Gate Cross site of grace outside Belurat, Tower Settlement.
2. Next, speak to Thiollier at the Pillar Path Cross site of grace.
3. Return to Moore and speak to him until he gives you the Black Syrup item to deliver.
4. Deliver the Black Syrup to Thiollier and ask him about it to receive Thiollier's Concoction.

3. Approach the Shadow Keep to Break Miquella's Charm

After exhausting Hornsent's dialogue, continue following the road north until you reach the Shadow Keep. As you get closer to its gates, a message will appear on your screen saying:

This message references Miquella finally shedding his Great Rune (you'll find it in the possession of the Scadutree Avatar). When this triggers, NPC questlines will advance, so make sure to speak to everyone before exploring the Shadow Keep and the rest of Scadu Altus.

How to Change Thiollier's Location

You can change Thiollier's location with two options:

1. Deliver Moore's Black Syrup to Thiollier, break Miquella's Charm, and exhaust Thiollier's dialogue to change Thiollier's location.
2. Reach the Garden of Deep Purple and tell Thiollier (back at Pillar Path Cross) about St. Trina's location.

If Thiollier's dialogue starts with I'm moving south..., that is an indication that he will depart to the Garden of Deep Purple once you reload the area in Pillar Path Cross.

After making sure that Thiollier is not by the Pillar Path Cross anymore, he will then be available as a gold summon against the Putrescent Knight later on.

4. Find St. Trina in the Garden of Deep Purple

You can find St. Trina in a cave in the Garden of Deep Purple to begin her questline. You'll need to reach the bottom of the Stone Coffin Fissure and defeat the Putrescent Knight to unlock her location.

How to Reach the Stone Coffin Fissure

Castle Front to Ellac River Cave
1	From the Castle Front site of grace, ride southeast until you reach a fork. This is where you turn right and through the small encampment.
2	Shortly after passing the guards, turn left on the fork and ignore the commotion on your right.
3	Follow this path until you reach the poisonous swamp area, so make sure you're on your steed before you continue. Once you see a giant flower enemy ahead, turn left.
4	Jump down the edge once you see a giant crab, then turn left into the cave, passing the flower enemies. Pass through this linear tunnel and you should arrive shortly at the Ellac River Cave site of grace.
Ellac River Cave to Ellac River Downstream
5	Exit the cave and immediately turn left to find a waterfall. Jump over the rocks while heading south until you reach another waterfall.
6	Take the left path that will shortly swerve you to the right side then keep following the path down to find the Ellac River Downstream site of grace.
Ellac River Downstream to Cerulean Coast
7	The next destination can be reached by hugging the right side of the path. Ride south and use the platforms to reach the base of the waterfall safely.
8	Follow the river south, ignoring the giant crab and the Furnace Golem, and turn right through the trees marked on the image above to reach Cerulean Coast.
Cerulean Coast to the Fissure
9	Continue heading south while staying on the left side this time. If this is your first time here, a Ghostflame Dragon will fly down towards you, but it can be ignored for now.
10	Keep following the road south, past the area with the ghost worms and pot-throwing giant, until you reach a crater at the end. You now have to make it safely to the bottom of this pit. Head to the west side of the crater to find the first platform that will take you down. Be careful not to fall into the abyss and watch out for the slime enemies on every platform as you go down.
11	Once you reach the site of grace at the bottom, it's only a short walk through the tunnel ahead until you reach the Fissure.

St. Trina Quest and Location

Thiollier Can Be Summoned in This Fight

You can also call for Thiollier's help before fighting the Putrescent Knight boss. His gold summon sign will only appear after Thiollier says he's heading south to find St. Trina.

Thiollier will tell you this after breaking Miquella's Charm, reaching the Fissure, and exhausting his dialogue at the Pillar Path Cross.

5. Die 4 Times by Drinking St. Trina's Nectar

Choose the option to Imbibe Nectar until St. Trina speaks on the death screen. Remember that you have to do this four times so it's best to spend your runes or use a Sacrificial Twig to prevent rune loss upon death.

Once she speaks to you, relay her words to Thiollier who should already be at St. Trina's location. Thiollier will not trust your words and will invade the next time you visit the Garden of Deep Purple.

Should You Choose to Imbibe Nectar?

The simple answer is yes, you need to choose the Imbibe nectar option since it is the only way to hear the words of St. Trina. Without hearing her words, both Thioller's and St. Trina's questlines would never progress.

6. Defeat Thiollier When He Invades

Imbibe Nectar again to progress St. Trina and Thiollier's questlines. Thiollier will invade you after you revive. Defeat him here to progress his questline along with St. Trina's questline.

7. Drink St. Trina's Nectar One Last Time and Speak to Thiollier

Choose the option to Imbibe Nectar until St. Trina talks to you again. Once she does, pass on her words to Thiollier to progress his questline. This is a necessary step to make Thiollier a summonable ally against Leda at Enir-Ilim and the Final Boss.

8. Summon Thiollier Against Leda at Enir-Ilim

Continue with the storyline and summon Thiollier to fight against Leda and her allies at Enir-Ilim. Interact with Leda's red summon sign to begin the battle between NPCs.

9. Summon Thiollier Against the Final Boss

Summon Thiolliier to fight against Promised Consort Radahn and Radahn, Consort of Miquella (Phase 2). This is a required step to drop Thiollier's weapon, armor set, and progress St. Trina's questline.
