Description
A unique monster that is generated and then killed usually will not be generated again, although it is usually possible to reanimate most unique monsters from their corpses or using stone to flesh on their statue, provided they leave a corpse (and are not corpseless) and are not immune to stoning in the first place (e.g. as with most quest nemeses). The Riders in particular are capable of resurrecting from their own corpses.
Unique monsters cannot have figurines generated of them, and wishing for one will result in a random figurine being given instead.[1] If the corpse of a unique monster would be left in a bones file, it is replaced with the corpse of a doppleganger, and a statue of a unique monster found in bones will turn into a doppleganger in the guise of that monster if revived via stone to flesh.[2][3] Trying to wish for a statue of a unique monster and reanimating it will also produce a doppelganger disguised as that monster.[4]
The primary exception to the rule of not being generated again after death is the Wizard of Yendor, who can resurrect himself one level stronger after each death.

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.

Since commit dc9fe0d8, scroll of scare monster on the ground and Elbereth no longer scare unique monsters.  Note that although the commit message only mentions the scroll of scare monster, Elbereth is also affected because it is handled in the same function.
