Rise of the Demon Lord
Skull of Hamfel
A large, demonic skull
The Skull of Hamfel is actually a helmet that magically adjusts its size to fit any size of head, so long as the wearer is humanoid. The outside of the skull is covered with boney spikes and is cold to the touch. Inside the skull are smaller spikes, half an inch in length. When the skull reshapes to fit the wearer, these internal spikes penetrate the wearer’s flesh and burrow into the bone.
The Skull of Hamfel is used as part of a ritual. It drains the powerful soul, or essence, out of a demonic entity and absorb it into the wearer.
