Azucar Skull

Tiny skulls made out of sugar and pieces from a dead humanoid's body such as skin flakes, hair, eye lashes, fingernails, etc. If consumed by a creature that knows a language and has an intelligence score above 3, the creature can communicate with the spirit of the dead humanoid that the skull was made out of. If the creature does not share a language that the humanoid knew when they were alive, it can still communicate through psychic visions that are more vague than spoken word.

These items are mostly created by hags, but some secret, magical markets have people that can make them for you.
