— In-game description[src]

The Archer's Handbook is a treasure found in Of Mice and Mechs of Sly Cooper: Thieves in Time. It is worth 211 coins and has a time limit of approximately 60 seconds to be returned to the safe house before it's lost.


It is a green and blue book with metal corners and a lock on the right side. On the front is a metal shield with three metal arrows behind it.


The Archer's Handbook is located at the north of the map. Enter the castle, then turn left and use the Archer Costume to shoot an arrow and cross the water. Then, switch to the Sabertooth Costume and pounce to the dummy to the north. This will open a Sabertooth Costume door, allowing you to grab the treasure.


  • According to its description, despite being an optional treasure, the Archer's Handbook is what allows Sly Cooper to control arrows after firing them while using the Archer Costume.
