Exploration and jumping puzzles in Guild Wars 2
This video from NecroBator and TenTonHammer shows some of the jumping puzzles that we started to hear about after the press beta event.
This area is part of the open world and is not instanced. At the end of the puzzle there is a boss waiting for you to be killed and a chest to be looted. Note that there are different types of traps, obstacles and environmental effects on the way to the top. As this takes place in a level 15 area, we can safely assume that there are more riddles and puzzles spread across the entire map.
