Chatas
Chatas: In the Liber de Angelis, Chatas is named as one of the demons in service to the infernal ruler
Barchan. Chatas is summoned as part of the spell for crafting a Ring of the Sun. This potent astrological talisman requires the blood of a white bird during its construction. Once finished, it can be used to bind the tongues of enemies or to summon a great black horse to claim as one's steed.
Several of the spells connected with this talisman require animal sacrifice, and the magician is cautioned to wear this ring whenever he carries out these sacrifices.
