Item generation
Base Type
Number of Items per Level
Levels in Hell, Slime Pits, and the Ecumenical Temple are generated without any items on the floor. Other levels contain between 6 and 36 items lying on the floor, chosen as described below; after level 5, there's a very small chance (about 0.2%) to get a very rich level instead, which contains 11-100 items.
Some levels (fixed bottom branch, random mini-vaults...) may contain additional "fixed" items, defined in the vault layout.
Type of Items Generated
Items in the Orcish Mines are always piles of gold; other items are randomly generated with the following weights:
| Item type | Probability | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| Weapon | 11% | |||||||||
| Ammunition | 15% | |||||||||
| Armour | 11% | |||||||||
| Wand | 3.6% | |||||||||
| Food | 7.1% | |||||||||
| Scroll | 16% | |||||||||
| Jewellery | 2.6% | |||||||||
| Potion | 9% | |||||||||
| Book | 1.5% | |||||||||
| Magical staff | 0.51% | |||||||||
| Gold | 22% | |||||||||
Miscellaneous evocable items may replace the generation of any item at item levels greater than 7.
If the item level is below 7 and the generator rolled a staff, a book or a wand, it may randomly change the item type to a potion or a scroll instead. Misc items (elemental evoker, summoning item or crystal ball) are only generated at item level 8 and after with a probability of 0.4% + 0.02% per item level.
Potions are generated with the following frequencies:
| Item type | Probability | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| Curing | 18.37% | |||||||||
| Heal Wounds | 10.05% | |||||||||
| Lignification, Flight, Haste | 6.99% | |||||||||
| Might, Degeneration, Agility | 6.32% | |||||||||
| Brilliance | 6.32% | |||||||||
| Mutation | 5.07% | |||||||||
| Invisibility, Resistance, Magic, Berserk Rage, Cancellation, Ambrosia | 3.35% | |||||||||
| Experience | 0.002% | |||||||||
