Devour Brain

One creature that you can see must be dead. The unconscious target is unaware of its surroundings, though it can still hear you telepathically.

Once you have eaten the brain, you may receive the answer to one question that the consumed brain knew the answer to. The answer will allow the target to recall the event with perfect clarity and exacting detail.

You must telepathically speak to the target to describe which of its memories you are searching for, and it must be able to understand your language for them to locate the memory. Its mind fills in any gaps in the details of your description.
