Arbitrary Unit of Mass
Obsolete: This article refers to an aspect of the game which has been removed. It is retained for historical reference only.
An aum (Arbitrary Unit of Mass) is the standard unit of weight in Crawl. It has no real-world equivalent; item weights are generally assigned according to game balance rather than realism.
Players have a carrying capacity of 100 + (25 * strength)
aum. If you are above capacity, you'll gain the encumbered condition.
