Dark Alliance II gives players the ability to create custom weapons, armor, rings, and necklaces through the shopkeeper. Players could increase these items by +1 to +5 (or +15 in extreme, but this can only be done with necklaces, rings, and boots.) using runestones, which were needed for all customizations and increased the item's power. A player could also use gems to add special effects to the items. Two different types of gems could be used on one item. There are several different kinds of gemstones and have a different effect on different types of items such as armour and weapons.
