One of the many commendations you can complete during the Dark Brethren Tall Tale is the Heart of a Thief commendation.
You can complete this commendation as soon as you enter the Dark Brethren’s Court at the top of the Coral Fortress during this Tall Tale. The Dark Brethren’s Court will be near the end of the Tall Tale, just before the final encounter.
If you need help completing the entire Dark Brethren Tall Tale, check out our full walkthrough here.
If you are just looking to complete Heart of a Thief, you’ll first need to solve the five-block puzzle!
How to solve the Five-Block Puzzle
If you are looking to solve the puzzle on your own, you’ll want to discover the five hidden Siren Murals throughout the Tall Tale.
Each Siren Mural is one of the five symbols found on the blocks in the puzzle.
Matching the blocks up with the Siren Murals in the correct order will allow you to solve the puzzle and open the hidden compartment it protects.
Though, finding the Siren Murals is not necessary to complete Heart of a Thief. You can simply enter the solution without finding them to solve the puzzle and complete the commendation.
Where are the Siren Murals
The five Siren Murals are hidden throughout the entire Tall Tale. Discovering all five will not only help you complete Heart of a Thief, but also unlock a different commendation called The Siren’s Call.
To reveal one, you will have to interact with three levers in a specific order in the area one is hidden.
You can discover all five for yourself by following along in this guide here.
