The second you pick up the powderstone DROP it and take this path
8 --> 7 --> 6 --> 4 --> 1 --> Base
Make sure you clear all areas (Some areas can't be cleared because the monsters will respawn but you'll need the extra help)
Backpacking is helpful but powderstone is already one of the easy missions, all you realy need is some Mega Juice and know how to NOT run in a straight line.
