While resting within telepathic range of a sentient creature you may siphon off their mental energy. You require a full uninterrupted hour to do this and when complete you are considered to be fed for the next 24 hours, the affected creature is not aware of you doing this and receives no side effects of being siphoned off. However, when you completed this siphoning you may feel the emotions and thoughts that creature had when you fed off it. Roll a d4, on an even result you learn, a small piece of information maybe pertaining to their backstory, their current emotional state, something that is bothering them, a particular fear they have, something they desire or a certain goal they wish to achieve. The choice is up to your Dungeon Master.
