Random encounters: Every so often a scripted event occurs in which a new character which has not been seen before enters the shop and either robs you or offers you a job or quest which requires you to complete extra activities to forge a weapon that is classed as a quest type weapon which can only be forged once using special quest materials which can spawn in certain points on the map this offers some variety to the often quite tiresome task of just repeating order after order until you can purchase the new metal. Also wizard staffs cause it would add to the medieval fantasy setting you got going on.
