The horned devil, &, is a major demon that appears in NetHack. It is considered the weakest of the major demons, with a lower monster difficulty than even the barbed devil despite having a higher AC. It is also ranked as weaker than the water demon, which has weaker attacks and a comparably good AC; this is likely because the water demon is faster, can swim, and may potentially appear much earlier.
The horned devil is flagged to only appear in Gehennom, but no lawful creatures can be randomly generated there; thus, they are effectively never randomly generated. This trait also occurs with barbed devils and the erinys.
These devils lack any real special abilities, though they
are quite difficult to kill.
