powderstone mission

The offline powderstone mission can be very annoying, however there is a tried and true technique that most people can pull off with a little bit of difficulty.

Start the way you would any quest, and proceed through to destroy the Gravios, you shouldn't have any trouble with it if you got to this quest in the first place. Once he's out of the way, head to area 9 (I think, I don't know the volcano areas by heart and it's a lot of work to go and check) Or wherever you get the powerderstone. Once obtained, drop it, and run out of the area, kill all the Ioprey until they stop respawning, proceed to the next area, the one on the left of the map, and clear the Apceros, go right through 4(?) and into the one with the Bullfango, clear them, and run back up to the powderstone area.

If you follow your cleared path, the only area of trouble will be area 4, which has infinite respawning Ioprey. If you zigzag enough, and keep an eye out, you can make it through and drop it in the box.

It helps a lot if you have some mega juice to give you unlimited stamina, obviously it's best used right before you pick up the powderstone that you plan on running back with.

If you use disc game, enter this in the AR Max:
WM75-96GW-T3DPN
02UG-CRN2-PFJFF
2V4W-NCPK-P6WXA

If you reach the powder stone location, take it. Then, Press circle, the powder stone will be broken. Use the Farcaster, you get back to the camp. The "Powder stone has broken" is keep showing. Go to the red box press X in front of it and done.
