Headcage is a spell that the casting Seeker can utilize to protect themselves or another person from a spell or ability that targets their mind, whether it is an attack or another type of mental penetration. The spell takes the form of a green aura which surrounds the head of the target. This aura vanishes after the spell has taken effect. This spell is strong enough to prevent the Professor from controlling Dante Vale's mind.
