Only Zuhl is a jumping puzzle located in Timberline falls, a level 50-60 area. This puzzle doesn’t require too much finesse with jumping, but you will come across a lot of mobs. You can avoid them or fight them, but you’ll need to fight a group event boss at the end.
The boss can be solo’d, but will take a few minutes to take down. You won’t be able to get the chest until after you defeat him, in which case it will appear once he’s down.
Watch the video to see how to make it to the boss, and optionally watch the fight, which takes up the majority of the video’s time.
