[Question] Training Areas for a Chief Bandit

Subduing the mutiny, try Hobis Leafre. Decent sniping spots along the middle, good drops, and low damage if you get hit by one. I wouldn't recommend Hankies for you, even though they're better exp. Hit too high, and no cover.
You could also try Ludi Clocktower, good spawn there always and a lot of so called "sniping spots."
