There, speak toMooreif you haven’t already.
He’ll give the item -Black Syrup- to you, and ask you to pass it on to Thiollier.
Progress along either of these paths far enough, and you’ll hear a great shattering sound.

She’ll resolve to start weeding out the unworthy from the group.
Don’t worry, this won’t do anything drastic.
Apparently they bloom on the southern shore, so he’s heading there to track down St. Trina.

What if you found St. Trina before Thiollier?
He will then be at theGarden Of Deep Purplethe next time you reload the area.
Head to the Fissure
The next stage of Thiollier’s quest involves quite a lot of travel.

So let’s dive into… all of that.
But simply put, it’s crucial that you follow the Ellac River down south below the Gravesite Plain.
After that, it’s just a long trek south down the river to reach the Cerulean Coast.

Use the large rocks as platforms until you reach the ground, then just keep charging south.
Just head directly south, killing or avoiding enemy threats as you see them.
With Miquella’s charm broken, however, you are free to enter the Fissure itself.

Be patient, don’t get greedy, and you’ll finish him off.
He also warns you against taking the nectar yourself, because it will kill you.
He’ll also tell you once again to leave him be.

Doing so will kill you, which is intended.
When you respawn, pick up your runes and then imbibe the nectar once again.
Defeat Thiollier
Rest at the Garden of Deep Purple Site of Grace to reload the area.

When you attempt to head towards St. Trina’s cave, you’ll find the way blocked.
Thiollier invades you at this point, and will fight you using his poison-spewing Perfume Bottles.
As he’s told you, he’s weak as a kitten really.

He’ll lament his weakness, and ask you to tell him what St. Trina said.
His summon sign will appear on the left just outside the fog wall of the final boss arena.
But hey, at least he fulfilled his master St. Trina’s wishes at the last.

After that’s done, return to the Garden Of Deep Purple and proceed into St. Trina’s cave.
St. Trina will have fallen to the ground, presumably dead along with her other half, Miquella.
In front of her, you’ve got the option to lootSt.

That wraps up this comprehensive guide to completing Thiollier’s questline in Elden Ring: Shadow Of The Erdtree.
