Molecular Immobilization

 is the ability to freeze someone or something in place. This state halts all physical, verbal and conscious reaction. When mortals are unfrozen, they are unaware of having been immobilized.

Examples

 * Endora used this power many times so she could cast a spell on Darrin.
 * Samantha cast a spell to freeze Darrin, Larry and the client, Jesse Mortimer, so they could not see Santa Claus arriving for a visit.
 * Aunt Minerva froze Adam's friend Roger Bennett.
