Extinctionist

|name=Extinctionist |number=63 |image=you_were_devoutly_aligned.gif |obtained=killing all the monsters in The Dungeons of Doom, save for The Master Of Thieves and the Mimic, 120 times. |text=You're entitled to the "Extinctionist" Trophy, for emptying out the Dungeons of Doom.}}

Notes

• Despite the trophy description and how it works in NetHack, killing 120 of each monster in the Dungeons of Doom doesn't stop that monster from appearing while you adventure there.

• Can be earned by killing monsters in the Dungeons of Doom over multiple ascensions.

References

• Extinctionist refers to the fact that, in general, no more than 120 of any creature may be generated in a single game of NetHack. Some players set themselves the task of making as many creatures extinct as possible.
• The image depicts the setup used by many NetHack players performing extinctionist runs - the player lures (summoned) monsters onto an altar surrounded by a boulder fortification and kills them, using the boulders to restrict the path of the monsters and using the altar to sacrifice their corpses for various rewards.
• The image name refers to the above setup, wherein the player would be rewarded by his/her god for sacrificing monsters on the altar. Curiously, the name is "Devoutly Aligned" rather than "Piously Aligned", the latter being the highest level of alignment.
