just check out te maps like c3,s2,etc..
even the drops of ores r very less..u kill all the creeps in ur way from c3 entrance to grinita entrance which is closed and all u will get is 1 or 2 stone pieces or if ur lucky a neri g..bt most of the times if u dont take the bosses u will reach empty handed...if no1 has noticed go n check it once..
