Thiollier and Saint Trina are the NPCs you meet at the beginning of the game in the Three-Path Cross Site of Grace Ring of Fire‘S Shadow of Erdtree DLC.
Initially, Thiollier is simply a seller of poison-related items, but his full story – along with that of St. Triny – She will need to be met during the rest of your stay in the Shadowlands.
Our Ring of Fire The DLC guide will take you through where to find Thiollier and Saint Trinaand all the steps you need to take to complete the quest line.
Thiollier and St. locations Trina
First, you’ll meet Thiollier nearby Path of the Pillar Cross Place of Grace in Gravesite Plain. You can reach him there before you take on Castle Ensis.
Later, after entering the Shadowkeep, you will be able to find St. Trina on the Cerulean Coast at Deep Purple Garden Place of Graceand Thiollier will move to be there with her.
Thiollier’s first encounter at Graveyard Plain
There is no need to rush to find Thiollier in his original location. Pillar Path Cross Place of Gracebut since his questline overlaps with Moore’s, it’s probably best to have that first encounter early on, before things get complicated. You can get there before you tackle Ensis Castle by crossing the Great Ellac Bridge, then turning right at the soldier camp.

Once you reach the Place of Grace and Miquella’s Cross, talk to Thiollier and exhaust his dialogue.
Contact Moore after meeting Thiollier
After your first conversation with Thiollier, return to the Place of Grace at the Main Gate in front of Belurat. Contact Moore and talk to him and he’ll give you some Black syrup for Thiollier.

Go to the Pillar Path Cross Site of Grace, give me the Black Syrup and then ask about Black Syrup. To choose I’m tired of life next and Thiollier will hand you over Thiollier’s potion. This is the item you will utilize with Dragon Priestess of Communion in Igon’s quest line.
Break the Great Rune (and Charm)
Before you can progress any further, you must break the great rune this is blocking your path. You probably haven’t seen it yet, but it’s time to deal with it.

To break it, you have to do this approach Shadow Keep. Just before you reach the front door, you’ll receive a couple of messages: “Somewhere a gigantic rune broke…” AND “And in the same way, it has its own powerful charm.” Both generally refer to Miquella and the NPCs you’ve met so far. Especially in the case of Thiollier and St. Triny’s great rune was blocking the path you need to go to now.
Reach the Stone Coffin Gap and defeat the Rotten Knight

At the very southern end of Southern Shores there is a crevasse you can climb (fall) down. This is your next stop. At the bottom you’ll find The Fissure Site of Grace at the entrance to the Cerulean Coast and the Stone Coffin Fissure – this is where the rune we broke was blocking your progress.

A little further you will come across Rotting Knight and unlock Deep Purple Garden Place of Grace. Once you do this, you will find yourself close to where Saint was hiding. Trina.
Head to the tunnel at the Garden of Deep Purple Site of Grace to meet Saint. Trina. She’s not very talkative. Don’t do anything with it for now. Instead, leave and then go to Thiollier.
Tell Thiollier about the whereabouts of Saint. Trina

Return to the Pillar Path Cross Place of Grace and talk to Thiollier. Tell him where St. Trina is.and he will move.

Ignore his warnings and go talk to Saint. Trina. If you have the opportunity, choose it drink nectar. As Thiollier said, it will kill you instantly. But that’s the plan, so trust the process.
Continue to be reborn in a place of grace, and then drinking nectar over and over again – four times in a row — until you hear the voice of St. Trina on a black screen before you are reborn.
Defeat Thiollier
Once you hear St. Trina’s words, go back and try to get the message to Thiollier. It will take two tries and he won’t open up.
Drink the nectar (and die) again. You will hear a little more from Saint. Trins in the obscure.

When you respawn, you will be attacked by Thiollier. Defeat him to pick up Saint Trina’s Smile Talisman.
Pass on the words of St. Trina
Enter the cave and talk to Thiollier again. Drink the nectar again. Die again.
This time when you respawn and talk to him again, Thiollier will finally listen to you. Pass on the words of St. Trina to him.

St. Questline Trina and Thiolliera will not end for some time. You need to complete the Shadow Keep, go through the Rauh Ruins, defeat Romina, Saint of the Bud in the Church of the Bud, and then utilize Messmer’s Kindling to burn the Sealing Tree.
This will open the Tower of Shadow and take you to Enir-Ilim: Outer Wall Site of Grace in Enir-Ilim. Before you go too far, it’s time to check out Thiollier one last time.
Talk to Thiollier
Return to the Garden of Deep Purple and talk to Thiollier – he won’t have much to say. Drink the nectar of St. again. Triny, listen to what he has to say now, and then return to Thiollier.
He probably still won’t have anything to say, but this way you can call him out on…

After completing all of Enir-Ilim, you’ll reach a gigantic arena where you’ll face off against the Knight of the Needle, Leda, and her allies — Freyja Redmane, Dan Dryleaf, and possibly Sir Moore.
You can summon Thiollier, and if you followed his questline, Sir Ansbach, to aid you in battle.
Thiollier’s fight is not over yet.

After defeating Leda, you’ll head to the Divine Gate for the final boss fight of the game. Before you go through the wall of fog, (possibly) summon signs will appear for your allies, Ansbach and Thiollier.
No matter how the fight ends, rest in the fresh Gate of Divinity, in the Place of Grace. Then you will find Thiollier’s corpse nearby, where you can collect it Hidden Thiollier Needle AND Thiollier’s set armor. (Ansbach may be here too.)
