Verica's Tomb Walkthrough Puzzle Guide Tomb of the Fallen Assassin's Creed Valhalla
In Assassin's Creed Valhalla there are places with good loot. Once you're done with them, you'll get a suit of armor. There were 4 of them initially, then 3 more tombs were added in game version 1.6.1. We will show how to solve the challenge in Verica's Tomb, which was just introduced.
Verica is one of the tombs that contains an artifact upon completion. The final tomb, which includes the new weapon, the Blazing Sword, will be unlocked if you have collected all five artifacts from the Tombs of the Fallen.
To access the riches within, you must solve puzzles in each Tomb of the Fallen.
