Killing Intent Experiment

Killing Intent Experiment is a form of experiment conducted by Ainz Ooal Gown.

Objective
Opponents tended to be sensitive to the emotions of strong beings like Ainz and end up getting dominated by fear. Thus it was possible for opponents to read others. Ainz Ooal Gown learned about this when he began receiving arms training with Cocytus. However Ainz himself couldn't sense the killing intent of others.

Procedures
To test out whether he could, Ainz forced Cocytus, who loathed the idea, to direct killing intent towards him.

Results
After the experiment, Ainz did end up feeling some pressure. However, he was not sure if it was actually killing intent that he felt. The Overlord hypothesized that perhaps the undead were just not good at sensing those kinds of things as they were completely immune against mental effects. He believed that sensing killing intent could be counted as a mental effect in a broad sense.

Trivia

 * It can be noted that Ainz's theory might not be true as, Shalltear Bloodfallen could sense it just fine. Though Cocytus believes that being a warrior allows one to detect it easier.
