[FAQ] • [doc]

Experiments are found in the Experiment cave, which is accessed during the Creature of Fenkenstrain quest. Completing the quest is not required to kill them, as you can simply push the farthest memorial from Fenkenstrain's Castle to access the area. In total, there are 18 experiment spawns in the cave: 7 sheep-dogs, 5 spider-men, and 6 wolf-women.

The wolf-women can only be killed during the Creature of Fenkenstrain quest. Attempting to kill one afterwards results in the message: "You don't have the heart to kill the poor creature again."

An experiment must be killed to obtain an experiment bone for the Rag and Bone Man's wish list, and to complete the Lab Clean-up Assistant achievement.

  • The sheep-dog experiment is a reference to a sheep dog, a breed of dog used to guard livestock.
  • The spider-man experiment is a reference to the Marvel superhero Spider-Man.
  • The wolf-woman experiment may be a reference to the Japanese anime Fullmetal Alchemist, specifically the character Nina Tucker, and her dog, Alexander.
  • Before the Evolution of Combat, experiments were a very popular training method because they had 1 Defence, max hit of 1 and had 1000 life points.
  • Experiments still use the old sounds for wolves and spiders when in combat. Additionally, they use older graphics for their models.
