Most items are generated at the same time the level is. A few are dropped by enemies such as Dragons. Items are also generated as part of treasure machines which at times make certain item types (such as rings) more common than they would otherwise be. The frequency at which different items appear is listed below. Items are never generated in hallways.

* The frequency of starred items is controlled by separate code. Keys are only generated as a part of a machine. The generation of Potions of Strength, Scrolls of Enchantment and food are strictly controlled by the game, ensuring that you have a steady supply. The Amulet of Yendor is guaranteed to be generated on level 26, and on each depth thereafter if you don't have it with you already. You should expect to find 6.67 potions of life per seed on average (99.7% of runs get 6-9, range 6-13, median 7). You should expect to find 8.67 potions of strength per seed on average (98.8% of runs get 7-10, range 3-10, median 9). You should expect to find 14.8 scrolls of enchanting per seed on average (98.3% of runs get 11-18, range 4-22, median 15).[1]
