Ring of Resource
The Ring of Resource can be obtained from the Larran's Big Chest at an effective drop rate of 1 in 475. This ring will automatically note any resources obtained within the Wilderness while equipped. Since fishing is an infinite source of fish, there is a 50 fish cap at which you'll have to start fishing again. It has unlimited charges and can be dismantled into 1-3 Larran's keys. It goes to refund box on death for a price of 25M coins.
