Immunity to sickness (also known as sickness resistance) is a property that appears in NetHack.

Description

A monster with immunity to sickness is completely immune to both food poisoning from tainted corpses and disease attacks from monsters like Juiblex. The following monsters have sickness resistance:

There are no items or corpses that confer immunity to sickness, but you can obtain the immunity by polymorphing into the above monsters.[1]

Disease attacks do not damage other monsters, regardless of immunity to sickness.

The following information pertains to an upcoming version (NetHack 3.7.0). If this version is now released, please verify that it is still accurate, then update the page to incorporate this information.

Per commit 017a868, disease attacks can now damage other monsters unless they have sickness resistance, addressing issue #594.

Green dragon scale mail and green dragon scales provide immunity to sickness.

Strategy

While the property itself is highly useful for specific cases (e.g. dealing with Pestilence and Demogorgon), the only methods to obtain it are polyself forms that are all but useless for combat and most other purposes.

The following information pertains to an upcoming version (NetHack 3.7.0). If this version is now released, please verify that it is still accurate, then update the page to incorporate this information.

Green dragon scales and mail make the property much more accessible, and some builds may consider it for their body armor if all other necessary properties are addressed, or else they are specifically on the hunt for Demogorgon.

History

In NetHack 3.4.3 and earlier versions, including some variants based on those versions, throne farming characters that set themselves up by a throne on an undiggable no-teleport level (such as a quest home level) and have enough Elbereth engravings and/or a boulder fort prepared may consider turning into a fungus or ghoul to cover the last remaining weakness using their immunity to sickness.
