Hand of Glory, a macabre twist.

I was surprised what this word meant, and particularly how it was used. I would imagine it would work,  if only out of sheer fright but if you read on, it was supposed to make the holder invisible.

Hand of Glory, n.
[‘ Originally: a charm made from or consisting of the root of a mandrake (see the etymology) (now rare). Later: a charm or talisman made from the dried and pickled hand of an executed criminal, used esp. (with a specially prepared candle placed within it) to render the occupants of a house motionless during a burglary.‘]

Various stories and legends exist concerning the preparation and use of the Hand of Glory.

A detailed description followed by many later texts is given by Francis Grose in Provinc. Gloss. (1787) 73-5. See also Scott Antiquary (1816) II. ii. 46-7.
