Can a arrow go through a deer's skull?

Yes, an arrow can potentially penetrate a deer's skull, especially if it is shot from a close distance with enough force and the right type of broadhead. However, the deer's skull is relatively thick and designed to protect its brain, so a direct hit is necessary for penetration. Factors such as the arrow's speed, weight, and angle of impact also play a significant role in whether it can successfully go through the skull.
