Most weapons found in loot are generic with their names, appearances and stats randomly generated from a limited list of templates. Other, unique weapons have fixed predefined properties, many of which cannot be found on generic equipment (e.g. rune slots). Unique weapons are usually looted from powerful enemies, found in heavily guarded treasure chests, or sold by merchants for exorbitant amounts of money. A number of top tier weapons come from promotions and DLC. These items become accessible in the beginning of Act 1 and can make game progression significantly easier.
