General Information[]
Boss insight[]
To get +15% permanent damage against the Void Beasts, you need to read a memory located in a secret room of the Kerguelen Gatehouse, right before the entrance to the boss room. Use a spell or damage talent on the Trick Wall behind the top most water wheel right ahead of the Gatehouse signpost. From there, follow the torches to guide your way until you find the prompt to enter the room. The memory is at the end of the Black Root-filled hallway at the end of that room.
