I'm supposed to go to Verdant Bank but I don't know how to get there. I'm in Dry Top and I tried to do the jumping puzzle there but I'm hopeless at it. Is there another way I can get through Dry Top or is that a necessity to continuing the story? I'm just after map completion and going through the storyline. I'm OK with missing some achievements etc. for now. I'm just not sure if the jumping puzzle is just an optional achievement or if I have to do it to continue Heart of Thorns. Thanks!!
