Mob mining or ore skinning is the act of gathering ore, gems, elemental ingredients, or vendorable items from the corpse of dead giants and elementals. To mine a dead mob, you must be at the appropriate level of mining. This is determined by multiplying the mob level by five. A level 70 mob requires a mining skill of 350 (70 x 5). A level 80 mob requires a skill of 450. Unfortunately, mining cannot be leveled in this fashion. Also, just as if you are mining a normal node, you must have a mining pick.
