This is a guide to consolidate all the information relating to the Halloween event in Guild Wars 2. Updated multiple times a day as I gather more info.
GW2 Tribulation Caverns is a new jumping puzzle introduced with the Halloween event. It is a puzzle located in SW corner of Dredgehaunt Cliffs, just behind the vista/jump puzzle for Tribulation Rift Scaffolding. You will have to sucessfully complete Tribulation Rift Scaffolding to gain entry to the caverns.
