Tainted Grail: The Fall of Avalon has many hidden quests and powerful rewards, and one of the best-kept secrets is the Red Death skill tree. This guide will show you how to find and complete the quest that unlocks the Red Death secret skill tree in Tainted Grail: The Fall of Avalon.
Step 1: Start ‘Perinde Ac Cadaver‘ Side Quest
To start the quest, make your way to the game’s second map, known as Konacht. Once there, head to the main city area and locate the hospital. Inside the hospital, you’ll come across a patient named Ignatius. Speak with him to initiate the quest titled Perinde Ac Cadaver.
Step 2: Head to the Toll House
After speaking with Ignatius in the hospital, travel east from the main city until you reach the fortress known as Toll House. Be prepared, as the entire castle is overrun with infected enemies.
Fight your way up to the very top of the castle. There, you’ll find an elevator and ride the elevator down to meet a strange person called “The One.”
Step 3: Deliver the Mark of the Plague
“The One” gives you a dark mission: deliver the Mark of the Plague to two people.
Yuna – You can find her in the part of town that’s infected by the plague.
Ignatius – Yes, the same patient you talked to at the start of the quest. You’ll need to go back to the hospital and give him the mark too.
Note: Before you give her the mark, make sure to finish her side quest. If you don’t, you’ll miss part of her story.
Step 3: Boss Fight
Once you’ve marked both Yuna and Ignatius, return to The One. He will then ask you to use the final mark on him.
Doing so will teleport you to a bloody and terrifying version of the asylum, where you’ll face a challenging boss fight against the Plague Wraith.
After defeating the boss, you’ll meet a mysterious character who is connected to the main story. Once the conversation ends, you’ll be transported back to the Toll House, where you will finally unlock the Red Death skill tree and receive the powerful Prophet Armor Set as your reward.
