Rings are listed in increasing order of base COST, then alphabetically by name. WGT specifies the weight (100 zorkmids weighs 1).
Rings comprise 3% of all randomly-generated items in the main dungeon, 5% in containers, 5% on the Rogue level, and 8% in hell. PROB is the relative probability of each subtype; the suffix specifies the chance of blessed/cursed:
|c||90% cursed, 10% uncursed, 0% blessed|
|charged||42.93% cursed, 41.33% uncursed, 15.73% blessed
|otherwise||10% cursed, 90% uncursed, 0% blessed|
Rings of invisibility carried by Nazguls are always cursed.
The CHG field is Y if the ring can be charged. The initial enchantment has an exponentially-weighted probability, but tends to be in the range of -3 to +3. When a ring with a positive enchantment is charged, it has an (enchantment before) in 7 chance of exploding. Rings with enchantments of <= -5 or >= +7 will always explode when charged. Otherwise, blessed charging adds 1 to 3 enchantments, cursed charging has a 50% chance of removing one enchantment, and uncursed charging always adds +1. Therefore, the highest possible enchantment is +9 by charging and +10 by random generation. You may repeatedly enchant and unenchant a ring.
The effects of rings are controllable by putting on and removing the ring. It is possible to obtain an effect permanently by polymorphing into a metallivore or gelatinous cube (depending on the appearance of the ring; see below) and eating the ring. There is only a 1/3 chance of obtaining the effect this way ("Magic spreads through your body as you digest the ring."). Note that the effect of eating rings that affect stats (gain constitution, gain strength, adornment) will not persist when you change from this form. Eating a ring of free action will confer sleep resistance instead. Rings of slow digestion may not be eaten ("This ring is undigestable!").
Meat rings have no effect when worn, but can be eaten as normal food (see Food). The appearances of other rings are randomized from the following descriptions.
|These can be eaten by a metallivore (rock mole, rust monster, or xorn):|
|The following can be eaten by gelatinous cubes:|
|These appearances cannot be eaten by any monster:|
