An term used to describe certain items in the online game
EverQuest - items which disappear when the character carrying them logs out of the game.
Making certain items no rent keeps players from hoarding them. For example, a character of the Magician class of high enough level can summon food and water. Summoned food and water are no rent items, which prevents a Magician from summoning and hoarding (or selling) 1000s of units of food or water.
