Description
Uniqueness is a particular and highly-specialized trait in the world of collectors of antiquities and purveyors of rarities. The more instances of a given item in the world there are, the less unique it is. Examples of item presence include items in containers, stowed away in house containers, worn by Adventurers in the Ivory Tower and so forth. Some locations are very exclusive and require that all who enter be wearing items of a certain level of uniqueness.
