I have been working on the waterfall quest and have found several things wrong with the walkthrough in the quest files.
first there are no chests to search in the gnome tree maze dungeon. its a set of boxes. and you have to talk to the gnome then search for the key.
second (and a major headache) is you cannot bring anything but food with you into glarial’s grave. you cannot even have it in your inventory on you.
third is that after you use the runes on the pedestals you have to use the neckless on the statue before the ground will rise.
please update the walkthrough. thanks.
