Chaos Crystal Cavern is a GW2 jumping puzzle located in Iron Marches. It’s a quick and easy one, though it may be frustrating if conditions are inflicted on you mid-jump.
Start off by heading to the southwest corner of Iron Marches. You’ll see a waypoint called Old Piken.
The method of completing this puzzle: jump from stone to stone. The catch: you’ll grab random conditions that affect the way you jump; from having the camera close up to your character, to far away, to gaining speed boons.
