How to extinct creatures
A creature is extinct when 120 of it's kind are born. The creatures do not have to be killed in order to be extinct. Once extinct, a creature will never be randomly generated again.
Therefore, you can extinct a creature simply by summoning, or reverse-genociding 120 of it's kind. Killing it is optional, but highly reccomended.
To extinct a creature, you must create it in a way that respects extinction.
Actions that respect extinction
- Reverse-genociding a monster.
- Casting create monster via spell, scroll or wand.
- Waiting around on a level for it to be randomly generated.
- Entering a level containing a special room such as a zoo, or beehive.
