Shadow of the Horns is a main quest that requires players to enter the All-Mother’s Temple.
Players cannot simply walk into the temple. If they do, they will be considered trespassers, and the guards will attack them.
To gain entry to the temple in Tainted Grail: The Fall of Avalon, players must first complete the side quest Acts of Kindness.
Starting The “Acts of Kindness” Side Quest In Tainted Grail
To begin the Acts of Kindness side quest, players must speak with an NPC named Vrann.

You can find her in a hut within the village, right next to the hill that leads to the All-Mother’s Temple.
Speaking with her will initiate a series of dialogues in which she explains that she wants to offer a gift to the Horns of the South.
You will be given the option to choose from several gifts, and you must advise her to offer a potion.

This will begin the quest, and your first objective will be to gather various ingredients needed to craft the potion.
Gathering Ingredients For The Potion
In the Acts of Kindness side quest in Tainted Grail, players will be tasked with gathering the following ingredients.
- Wolfsbane x5
- Moonshine x1
- Iron Tooth x3
Wolfbane can easily purchase it from Jann Heber at the Horns of the South main town square.

You can also collect them from the hill near the Senan the Giant landmark. Make sure to collect five of them.
There is no guaranteed way to collect Moonshine. You should try your luck by searching bandits, as they may have the item.
Similarly, players can obtain Iron Tooth by defeating Red Cap enemies and looting their corpses.

Players need to collect 3 Iron Tooth, each dropped by Red Cap enemies found in the northern area of the first region’s map.
Once you have gathered all the ingredients, bring them to Vrann so she can prepare the potion and ask you to deliver it to Fearghas.
Go to Horns of the South and speak with Fearghas to start a dialogue between you.

After a brief conversation, he will give you a barrel of fish to deliver to Vrann as a thank you.
With the return gift in hand, return to Vrann’s hut and present it to her. She will reward you with Vrann’s Key.
Vrann will grant you access to the All-Mother’s Temple, and the guards will no longer consider you a trespasser.
