Brain Eating. On devouring a humanoid brain, the gu'en deeko gains the knowledge of the victim. It also gains levels, spells, and abilities of the victim, including languages, etc.. These memories and skills fade after a year if not consumed, as in the case of spells, which cannot be relearned in a normal fashion. Hit points gained become permanent addition (limited to their monstrous nature, 6d10+18), and are regained upon resting.
