Experiment

Experiments can be found in the Experiment Cave which can be accessed during Creature of Fenkenstrain quest. Completing the whole quest is not required to kill them, as you can simply push the farthest memorial from the castle and you will enter finding quite a few of them.

Varieties
The level 25 experiment hits very low and has a lot of health for its level, making it one of the easiest monsters to level up the combat skills. They have virtually no accuracy, strength, or defence whatsoever, so most people do not bring armour when fighting these. It was one of the chief training tools before Pest Control first came out, and since the recent updates to Pest Control which lowered the experience gained by about 30%, it is once again a chief training tool for players.

The level 51 experiment may only be killed once, (unless you drop the cavern key obtained by killing it), during the Creature of Fenkenstrain quest. It is significantly stronger than the level 25 experiments, with a max hit of 7.

Experiments are comparable to Hill Giants in free to play worlds in that it is normally a battle around each spawn point to gain the experiment.

Trivia

 * The half sheep, half wolf may refer to the saying "A wolf in sheep's clothing", or possibly a sheep dog.
 * The half man and spider may refer to Spider-Man.

Note

 * Training mage against the Experiments may not be cost effective considering they have no drops. This means the money spent on runes will not be covered. When possible, it is suggested to switch to Skeletal and Zombie hands instead.
