I can't find L2 even after reading this thread.
I have the climbing gloves and returned to Sandgaze Village, but seems like I only can trek to Mount Hydrill and then there are two ways to Hydrill Swamp, one requires hammer and the other is completely blocked up by poisonous gas. I don't understand.
Do not be surprised that I ask for help, most of the finished quest is by T_K. Also don't be just because I do it now. I do not have any time nowadays.
