mhhh lets compare it to mm... it takes 3,5-4,5 hours to climb + 3-4 hours for the mm itself -> 6,5-8 hours for min 3-6 gp (in case of fail)
6,5/1,25= 5,2 and 8/1,25= 6,4; so this gains u 5,2-6,4 gp in the same time like mm, but it depends on time. i didnt count breaks and time for muling and stuff
rly amazing
