Mehehe. I didn't know they break. Hmmm... Just got the advice from another player about those escape boots... How long before they break? Is it related to the number of times you escape from battle using that equip?

The good thing about oslya is the aluminum ore and pure iron ore mixed in with the quartz. You could sell of the alu ores from 50g to 120g. I'm not quite sure about the pure iron. Or you could compound the alu ores into hard alu plate or alu plate to get more cash.
