Monsters (by experience)
This is a list of monsters in NetHack sorted by base experience value, then by monster difficulty.
This table was generated with the use of a modified version of nhtohtml to calculate experience values as well, and are believed by the author to be accurate. If there are discrepancies between these and those listed in the articles, please correct the article.
In this table, "base" experience value refers to the number of experience points earned by the hero for killing the monster, assuming that the monster's level is equal to its base level. For more details about how the experience value of a monster is calculated in general, see experience points.
The giant eel, electric eel, and kraken are worth 1000 fewer experience points if you are wearing an amulet of magical breathing or are polymorphed into a form that cannot be drowned.[1]
