Description: Prevent new spells from being cast in a square for a limited time.
Uses: Casting Entangle (Green) on the opponent while at the plant-overgrown square in Exam 6 will cause him to become trapped, to which he will respond by trying to free himself with magic. Following up with this spell is likely to thwart these attempts, keeping him trapped for even longer.
