Dragon scale mail, also known as dragon mail and commonly abbreviated as DSM, is a type of magical body armor that appears in NetHack. It is made of dragon hide.

Generation
Dragon scale mail is not randomly generated, though they can be wished for or found in bones.
Dragon scale mail can be created by reading a non-cursed scroll of enchant armor while wearing a set of dragon scales: the scales will transform into dragon scale mail if the scroll enchants them, and a blessed scroll will add one point of enchantment.
Player monsters that are not monks generated on the Astral Plane have a 1⁄9 chance of generating with dragon scale mail as their initial body armor before role-specific replacements.[1]
Description
While worn, all forms of dragon scale mail confer 9 base AC, the most of any single piece of body armor. Dragon scale mail also confers an extrinsic property while worn, based on the color of the armor:
Uncontrolled polymorphing while wearing dragon scale mail will turn the wearer into that color of dragon and revert the mail back to scales.[2][3] Black, gray, and silver dragon scale mail have a base price of 1200zm, and all other types of dragon scale mail have a base cost of 900 zm.

Gold dragon scale mail is added per commit 5a09a01a along with the corresponding dragons, and acts as a light source while worn. Per commit ef1eeed7, they and other dragon scale mail types that are not gray or silver grant additional extrinsics while worn - the dragon scale mail extrinsics for 3.7 as of this commit are listed below:Strategy
Dragon scale mail is the strongest and most sought-after type of armor in NetHack: it provides a stellar amount of AC for only 40 units of weight, is made of an intrinsically erosion-proof material, and does not block spellcasting - even the least useful dragon scale mail is likely to do much more for a hero than most other body armor. One of the few things it does not provide is magic cancellation, which can be remedied with other armor or items such as a high-MC cloak.
The most common methods of obtaining dragon scale mail are:
- Wishing for it directly - dragon scale mail is a common early game wish, especially when a hero finds a random wand of wishing.
- Acquiring dragon scales in some manner and making them into mail using a scroll of enchant armor.
- A lucky player may happen across the bones of a former hero with dragon scale mail in them, though whatever killed that hero will likely be trouble for the finder as well.
When wishing for your preferred dragon scale mail, make sure to spell out and phrase the wish properly, or you may end up with a scroll of mail. Take care to avoid polymorph traps and other sources of polymorph while wearing dragon scale mail, especially if you lack a source of magic resistance: while dragons are decent polymorph forms, the loss of body armor and AC is quite annoying even at best - re-crafting the dragon scale mail will also take another scroll, and scales with an enchantment of +4 or above risk being evaporated entirely.

Overhaul the sections below to reflect DSM changes and extrinsic resistance buffs.Gray versus silver
The most coveted varieties of dragon scale mail are silver (for reflection) and gray (for magic resistance), though players disagree as to which of the two is more useful in particular circumstances. The article linked at the top of this section goes in-depth with regards to which choice may be most appropriate for a given hero and/or scenario, particularly in regards to early game wishes and availability of other sources for either property.
Other colors
Even with the popularity of heroes using gray or silver dragon scale mail, there are certain builds and strategies where another color is preferred. Some examples of these use cases are listed below:
- For wishless ascensions, while it is possible to obtain obtain DSM without a wish via reverse genocide, some unfortunate heroes may not find scrolls of enchant armor or genocide or come across a means to write either one in a timely manner - in these cases, it is worth enchanting the first set of dragon scales found, even if only for the AC benefit and weight reduction. This may also be an option for players whose heroes lack a bag of holding and want to manage their inventory weight without resorting to constant stash trips.
- Players attempting foodless or even vegetarian conducts can get most resistances through crowning, though this may be undesirable in some circumstances e.g. foodless atheist play (which makes crowning impossible). Heroes observing these conducts that have magic resistance and reflection from other sources may consider the following colors of dragon scale mail:
- Red dragon scale mail protects against the fire traps in Gehennom - while it can be superseded by the ring of fire resistance, the ring must generally be identified in some way first.
- Green dragon scale mail protects against instadeaths and extra damage from spiked pits, poisoned missiles and poisonous melee attacks. The ring of poison resistance and amulet versus poison similarly warrant identification of some form as with red dragon scales: green dragon scale mail can also be superseded by reaching a given experience level for certain races or roles, or else finding an alchemy smock. It may be a likely candidate for a foodless atheist that obtains an early wish, especially if using a role/race combo that does not gain eventual access to the property.
- Orange dragon scale mail protects from sleeping gas traps, sleep rays, potions of sleeping (including their vapors), and the orange dragon's breath weapon. Elven heroes can obtain sleep resistance at experience level 4, but the property lacks other sources and can only be partially covered by a ring of free action.
- Yellow dragon scale mail is a very rare consideration: though acid resistance is difficult to obtain short of polymorph or else an alchemy smock, acid attacks are themselves rare and not often a threat, and acidic passives can be avoided with most forms of ranged attack.
- Black dragon scale mail is similarly rare: the only sources of disintegration resistance are the black dragon itself, but a hero with reflection can trivialize the threat of their breath attack, then consume their corpse or tin for insurance should they lose their reflection somehow.
- Reflection-less play changes considerations significantly, and may open up the possibility of using different colors for harder-to-obtain properties: heroes that already have magic resistance covered may consider black dragon scale mail in particular to avoid being surprised by an offscreen disintegration blast - the property is still supersedable afterward by eating a black dragon corpse or tin (with the exception of foodless or vegetarian conducts), and some players may opt to genocide black dragons instead.
Pets and DSM
Humanoid pets, on the other hand, will appreciate certain "off-meta" colors of dragon scale mail more, depending on their own intrinsic resistances:
- Mind flayer pets are especially vulnerable to passive attacks due to their multiple hit dice, and yellow dragon scale mail in particular may be worth considering for them.
- If you lack a spare reflection source, black dragon scale mail can protect a humanoid pet against a black dragon's breath weapon.
History
Dragon scale mail first appears in NetHack 3.0.0. From this versions to NetHack 3.0.10, including variants based on those versions, there is only one type of dragon scale mail: it provides fire resistance while worn, and is created by polymorphing the corpse of any dragon.
NetHack 3.1.0 introduces the different colors of dragon scales and dragon scale mail except for silver, and establishes the current methods of creating dragon scale mail. Silver dragons, silver dragon scales and silver dragon scale mail are introduced in NetHack 3.3.0.
Variants
In some variants, dragon scale mail is phased out in favor of dragon-scaled armor, whose implementation is based on a proposal by dtsund. Instead of being made into mail of its own, the dragon scales are treated as a cloak, and reading a scroll of enchant armor melds them onto a worn set of body armor, generally augmenting that armor by adding its AC and conferred extrinsic properties to it.
Scrolls of enchant armor will always target worn dragon scales instead of other worn items: a blessed scroll will bless the body armor that the scales are melded to and repair any erosion (but will not erodeproof it), while a cursed scroll will cursed the body armor and lower its enchantment by 1 point. If the armor is already dragon-scaled, fusing another set of scales replaces the previous color. If reading a scroll of enchant armor while wearing scales without body armor, the hero will polymorph into the matching type of dragon, with polymorph control allowing you to choose whether to transform - if read while confused and wearing both scales and body armor, the scales fuse into the armor before your character polymorphs into a dragon.
Dragon-scaled armor is implemented in NetHack Fourk, xNetHack, EvilHack, and Hack'EM - these implementations differ from the proposal and from each other, and are covered in detail by the article linked above.
Several variants also give dragon scale mail additional properties while worn, and may even introduce other forms of dragon scale armor. Variants with object properties and/or partial intrinsics can also shift the use of other colors of dragon scale mail as well, generally creating more useful options.
SLASH'EM
SLASH'EM introduces two new types of dragons, and thus two types of dragon scales and dragon scale mail:
| Color | Extrinsic |
|---|---|
| Shimmering | displacement |
| Deep | drain resistance |
SLASH'EM also makes several changes with regards to how dragon scale mail can be made or obtained:
- Baby dragons are more common to encounter in the dungeon, but take much longer to grow up into adult form, and polymorphing for monsters works as it does for the hero, meaning that pets cannot be polymorphed or otherwise reliably farmed for scales.
- The Wyrm Caves generates several adult dragons at level creation, providing a plentiful source of various scales.
- Shopkeeper services for used armor dealerships may include the ability to enchant armor - this allows illiterate heroes to obtain dragon scale mail without wishing, though only 1⁄4 of such shopkeepers will offer it.
- There are sources of guaranteed gray dragon scales/dragon scale mail in the Lawful Quest and the black market, respectively, though both are quite difficult to liberate from their owners.
- Some gnolls can be generated with dragon scale mail:
- Gnoll warriors have a 1⁄20 chance of receiving orange dragon scale mail.[4]
- Gnoll chieftains have a 1⁄10 chance of blue dragon scale mail.[5]
- Gnoll shamans have a 1⁄10 chance of silver dragon scale mail, and otherwise have a 1⁄5 chance of generating with red dragon scale mail.[6]
Though gray and silver are still popular colors of dragon scale mail, strategic uses of other colors are more common as well, especially for heroes that seek to obtain magic resistance and reflection by other means: SLASH'EM features several more level-draining threats, such as the wand of draining and the breath weapon of deep dragons; shimmering dragons are tougher to hit than other monsters, while making displacement obtainable without sacrificing the cloak slot typically used for MC3; and stronger acidic threats such as the shoggoth and giant shoggoth make yellow dragon scale mail's acid resistance much more viable.
NetHack brass
In NetHack brass, dragon scale mail weighs 250 aum and provides 8 AC.
GruntHack
GruntHack's implementation of object properties makes it possible for dragon scale mail and other magical items to have an additional property, unlike implementations of object properties in later variants. Since it is possible and commonplace to wish for an item that provides both magic resistance and reflection (e.g. usually "blessed greased +3 dragonhide cloak of magic resistance and reflection"), the remaining properties are usually covered via other wishes.
The result is that the choice between gray and silver dragon mail (or most other colors) for wishes is rendered moot: assuming a first wish to cover both magic resistance and reflection such as the example provided, yellow dragon scale mail of decay (which adds drain resistance) is the most common secondary wish for a majority of heroes, as it blocks two of the most pressing remaining threats: drain life and acid blast, which hostile spellcasters of certain levels can have access to. Most heroes that obtain wishes can also tailor their dragon mail choices to fit other desired builds - heroes of laying races that cannot wear body armor, such as giants, will have to consider a different series of wishes altogether for their property coverage.
SporkHack
SporkHack adds gold dragon scale mail, which act as a permanent light source while worn. Most sets of dragon scales and dragon scale mail are also given a secondary extrinsic:
| Color | Extrinsic | Secondary extrinsic |
|---|---|---|
| Blue | shock resistance | speed |
| Black | disintegration resistance | passive blinding attack |
| Gold | light source | none |
| Gray | magic resistance | none |
| Green | poison resistance | passive poison attack |
| Orange | sleep resistance | passive slow attack |
| Red | fire resistance | +1d6 to all melee damage |
| Silver | reflection | none |
| White | cold resistance | freezes water and lava under foot |
| Yellow | acid resistance | stun and confusion resistance |
dNetHack
In dNetHack, notdNetHack and notnotdNetHack, dragon scales can made into dragon scale shields as well as dragon scale mail - reading a scroll of enchant armor while confused will harden worn dragon scales into a shield. All dragon armor and corresponding scales are given one or more secondary properties similar to SporkHack and other variants, with some being exclusive to particular types of scales or armor. Dragon scales and dragon scale mail also weigh 150 aum. Deep dragons and shimmering dragons are added along with their scales and armor.
UnNetHack
In UnNetHack, dragon scale mail confers only 5 base AC. The powers of dragons and their scales (and thus scale mails) are also randomized in each game:
| Appearances | Powers (randomized each game) |
|---|---|
| tatzelworm | "magic" |
| amphitere | "reflecting" |
| draken | "fire" |
| lindworm | "ice" |
| sarkany | "sleep" |
| sirrush | "disintegration" |
| leviathan | "electric" |
| wyvern | "poison" |
| glowing* | "stone"** |
| guivre | "acid" |
| chromatic | all |
A glowing dragon will always emit light within a 2-square radius of itself - glowing dragon scales (and glowing dragon scale mail) do the same while worn. The dragon that produces stone dragon scales will always have a breath weapon that creates lava.
UnNetHack also makes significant changes to wishing rules: In particular, dragon scale mail and other magical items can only be obtained by a wish from a wand of wishing; dragon scales are non-magical and can be obtained from any wish source in UnNetHack. Any set of dragon scales or its corresponding mail can be wished for by appearance, e.g. wishing for "guivre scales", or "guivre scale mail" from a wand of wishing, will always work. To wish for dragon armor by its corresponding power, the armor must be formally identified first, e.g. by using a scroll of identify on dropped dragon scales (which identifies the matching scale mail along with it) or by witnessing the dragon use its breath weapon. The name of the power can then be used in the wish, e.g. "reflecting dragon scale mail".
FIQHack
FIQHack implements the shimmering dragon and its scales (and scale mail). Dragon scale mail now weighs 300 aum, and the weight of all worn armor is halved.
Dragon scale mail (and corresponding scales) confers additional benefits while worn:
| Color | Extrinsic | Secondary extrinsic |
|---|---|---|
| Blue | shock resistance | speed, slowing resistance |
| Black | disintegration resistance | drain resistance |
| Gray | magic resistance | none |
| Green | poison resistance | sickness resistance |
| Orange | sleep resistance | free action |
| Red | fire resistance | infravision, warning, see invisible |
| Shimmering | Displacement | stun resistance |
| Silver | reflection | behaves like vanilla reflection (reflects dragonbreath and rays from wands used at Skilled or higher) |
| White | cold resistance | automatic searching, swimming, magical breathing, wetproof inventory |
| Yellow | acid resistance | stoning resistance |
Encyclopedia entry
Stephen had argued, and the expert armorer had grudgingly
admitted, that dragonscale shield or armor, provided it proved
feasible to make at all, ought to offer some real, practical
advantages over any metal breastplate or shield -- gram for
gram of weight, such a defense would probably be a lot
tougher and more protective than any human smiths could
make of steel.
