Vitalis of Milan's Chains

Origin
Vitalis was a very wealthy citizen of Milan who was buried alive in the first century for being a Christian and became a martyr.

Effects
These chains are the ones that he was bound in and buried alive with, allowing the user to lower the density point of any person they touch and phase them under the ground. They also release a howling scream of a man in pain that will not go away until the person becomes solid again.
