Where To Find Jumping Puzzles
Straits of Devastation – Viziers Tower, Underwater Puzzle (no achievement)
This puzzle will end up being found by most people looking for the vista and skill point. Overall the puzzle is in the southeast of Straights, but southwest of Fort Trinity. Starting southwest of the island the vista and skill point are situated on. The closest waypoints are Lone Post or Broken Spit but they are often contested. Fort Trinity waypoint is often the most reliable choice.
There is a second puzzle (no achievement) in Malchor’s that is less a jumping puzzle more a time based underwater dodging challenge. You can find it directly west of the Fort Trinity waypoint.
