There are many ways to loot at the South Idol. The most common and popular way is to use a blunderbuss with steel shot. This just kills all of the ghosts in one shot with no real difficulty (to do this a pirate must have a pretty good Eagle Eye rank and must be aiming at the farthest away ghost). But, there are many other ways. This is off topic but if ye are searching for good weapons such as famed or legendary. Also, go to tormenta with swift foot glitch with blunderbuss and do laps. For more infomation on this see Leon Dreadpratt's Guide to Looting.
