Eating jewelry

From NetHackWiki
Jump to: navigation, search

Eating jewelry is a method to permanently gain the intrinsics conveyed by wearing some rings and amulets. To eat a ring or amulet, one must first polymorph into a creature that can eat the material of the ring or amulet.

The material of a ring is dependent upon its randomized appearance, not its function. Not all rings are edible, so the set of rings that can be eaten varies from game to game. All amulets are iron so are edible by metallivores, specifically rock moles, rust monsters, and xorns.

Eating a ring has a one in three chance of conveying its powers to the eater, while eating an amulet only has a one in five chance of conveying its powers.[1] If the intrinsic is granted, you get the following message: "Magic spreads through your body as you digest the {ring|amulet}" as opposed to the traditional intrinsic gain message.

Eating other metal items only confers nutrition.

Artifacts are treated as their base items for eating purposes. This means that you can accidentally eat your great weapon or quest artifact. It will then be lost forever.

Notably, eating a ring of conflict, regeneration, hunger, warning, polymorph, polymorph control, increase damage or increase accuracy will give you a property that is not otherwise obtainable intrinsically to some characters. However, only warning, polymorph control, and increase damage/accuracy have no downsides.

Regeneration and conflict permanently increase your hunger rate in addition to their useful properties; hunger, of course, simply does so with no benefit. These effects are cumulative. Hunger from eating rings of regeneration or conflict is part of the regeneration or conflict effect itself, and thus cannot be separately removed by a gremlin.

Polymorphitis is not a desirable property even for characters with polymorph control: each polymorph still has a 20% chance to polymorph you into your own race, in which case random stat shuffling can occur.


SLASH'EM offers five new ring materials and five new functions. Ridged rings can be eaten by any metallivore. The other four, wedding, obsidian, plain, and glass rings, cannot be eaten by any monster.

Ring Intrinsic granted

The only amulet which is generally useful to eat is the amulet of magical breathing. All the others either give no effect, a property which is easily obtainable otherwise, or a property which is downright harmful.


You will usually need to eat many rings or amulets to get any given intrinsic. If you are limited in ways to polymorph yourself it's important to have duplicates readily available, so you can eat them all before you revert to your normal form. Short of polypiling it is unlikely you'll have enough to be almost certain to get the intrinsic for amulets:

Rings Eaten Likelihood of Intrinsic (%)
1 33.3333
6 91.2209
12 99.2293
18 99.9323
23 99.9911
29 99.9992
Amulets Eaten Likelihood of Intrinsic (%)
1 20.0000
11 91.4101
21 99.0777
31 99.901
42 99.9915
52 99.9991


A user has suggested improving this page or section as follows:

"There was an rgrn thread some time ago stating protection does not wrap around, i. e. it is stored in a 16-bit integer and clipped to 8 bit after the fact."

The amount of protection or damage and accuracy bonus you can obtain this way is only limited by the number of rings in the game (provided they have an edible appearance). However, these attributes are stored in a signed integer, so you do not want your total bonus (including weapon / armor type and enchantment, skill level, worn rings etc) to exceed +127 lest it wrap around and become negative.
