Do no act of an ov (type of medium)
“Do not turn to ghosts” Vayikra 19:31
A medium is one who performs some actions until the inquirer hears as if someone is talking to him from underground.
Also a person who takes a skull of a dead man and conjures as if a voice emerges from under his armpits and answers him.
The person who requests this and the one who is consulted both violate this prohibition.
This applies in all places at all times for men and women.
