Sister Victoria's Vexation

Access the Hangout Events menu via the Quest menu, then Story sub-menu. Select Barbara and confirm to unlock "Wellspring of Healing".

Teleport to the upper Mondstadt waypoint (a marker on your map you've manually placed as a destination) and glide northwest towards the Cathedral. Speak with Sister Victoria outside the Cathedral.

She will ask you to find Barbara, mentioning Barbara was heading towards Wolvendom.

Teleport to the Wolvendom waypoint and head southwest, near the Andrius Boss arena. Find Barbara near a tree by a Pyro torch.

Talk to Barbara. She is looking for Red Wolfhook Berries. After some dialogue, you will be presented with your first choice: _“Because… Well, just because”._

Choice 1: _“Just wait here, we’ll go send that person away.”_ This ends the current quest and leads to Branch 1-A, "Sudden Shouting".

Choice 2: _“Let’s go deeper into the forest and wait for them to leave.”_ This leads to Branch 1-B, "Temporary Relief From the Fanfare".

If you chose Branch 1-B, follow Barbara west behind a tree. Ask her _“Why are you trying to avoid being seen?”_

After Barbara explains her popularity and desire for alone time, she will say _“I guess that’s all we can do for now. Although, it certainly isn’t nice to treat someone that way…But today, I simply wish to keep to myself.”_ You will have three choices:

Choice 3: _“Wouldn’t your family worry about you picking herbs all alone?_

Choice 4: _“So what made you decide to join the Church, Barbara?_

Both Choice 3 and Choice 4 lead to backstory dialogue. Barbara will then mention _“There’s nothing wrong with the Holy Lyre der Himmel… is there?_ You will have two choices:

Choice 5: _(Look at Barbara with an innocent gaze.)_

Choice 6: _“Th–The Holy Lyre? Oh… Um, I wouldn’t know…”_

Both Choice 5 and Choice 6 lead to Barbara brushing aside the question. She will then state she still needs to find Red Wolfhook Berries. You will have two options:

Choice 7: _“I’ll lend you a hand.”_ This leads to Branch 2-C: "Of Wolfhooks Red".

Choice 8: _“We can go look together.”_ This also leads to Branch 2-C: "Of Wolfhooks Red".

If you proceed to Branch 2-C, you will need to search for 5 Red Wolfhooks.

Two Red Wolfhooks are under a hollowed log to the east.

One more is in a tree stump southeast of those.

The final two are under another hollowed log southeast of Barbara, in the center of the objective marker.

After collecting all five, talk to Barbara to end this quest and unlock the next quest, "The Church’s Affairs".

Alternative Ending Choice: If you chose _“It’s alright, this is a perfect place for two people to spend some time together._ after collecting the berries, it will lead to an embarrassing ending for Barbara and conclude the quest.
