Here is a list of all the GW2 jumping puzzles in Guild Wars 2 with video tutorials and instructions on how to complete each of the puzzles.
GW2 Shaman’s Rookery is a simple jumping puzzle located on the west end of Wayfarer Foothills right below the Zelechor Hot Springs Waypoint. There is a cave entrance that you need to locate that will lead you to the puzzle.
Once you are inside the puzzle, you need to navigate the platforms, avoid the red circles from the ravens (they will knock you off the platform, forcing you to start over), and fight any NPCs that become active (they all have a nasty knockdown/knockback so it is best to not fight them near the edges). This puzzle is short and a serves as a good learning experience for later ones.
