Like the serpents, these men are mere dupes of the loa! This Conjurer's Sphere will not hold them physically, but it should contain Damballah! 
The Conjurer's Sphere was a spell that created a mystical sphere to contain arcane threats without physically restraining others.[1]
History
When the serpent demon Damballah attacked Doctor Strange with possessed men, Strange used the Conjurer's Sphere to safely contain Damballah's thralls.[1]
To capture Clea, Baron Mordo disguised himself as a cat, snuck into the Sanctum Sanctorum, and trapped Clea in the Manacles of Mokarr. Baron Mordo then attacked Doctor Strange with eldritch energy that Strange formed into a Conjurer's Sphere.[2]
