Outside the tomb, Selket had a working cult among the living. Egypt's scorpions and venomous snakes were a real and constant hazard, and a class of priest magicians called the followers of Selket practiced the treatment of stings and bites as her sacred office, reciting spells that cast the sufferer's pain as a story in which Selket herself intervenes. The most famous of these texts, the Metternich Stela, is a tall block of magical spells and mythic narrative carved so that Nile water poured over it could be drunk as a cure, and Selket appears in it beside Isis as one of the goddesses who saves the infant Horus after a scorpion stings him in the marshes of Chemmis.
That story captures the paradox at the center of her cult: Selket both sends venom and withdraws it. Egyptian ritual texts sometimes have the goddess speak in the first person, commanding the poison to leave the body the way it entered, a formula that treats the goddess as identical with the venom itself rather than merely its mistress. Because of this, Selket was also drawn on protective amulets meant to be worn rather than read, small scorpion charms placed on children and travelers in regions where the insect was common.
She is rarely given temples of her own scale beside deities like Isis or Hathor, and her worship survives mostly at this intersection of medicine, magic, and mortuary practice, a goddess invoked at the exact moment danger is present, whether in a birthing room, a desert road, or a sealed tomb chamber two thousand years after her power was still thought to be enclosed within it.
