The Crafting Part
You will start from raw materials,craft them into equipments,and enchant these equipments.
For example: Iron Ore->Iron Ingot->Iron Sword
Fire Ore->Fire Essence(magic stone)
Iron Sword+Fire Essence=Fire Element Iron Sword
You need to balance the wages and capacity of your staff to craft low cost and high power weapons,complete missions,make profits.
The cost(wage of staff) depends on all five of staff's attributes point,while the quality of weapon crafted depends on one relative attribute point(so it is recommended to train crafting staff extremely strong in one relative field)
