Nightmare Steel Cage (3.5e Spell)

Those caught within this spell’s area are first trapped within the area of effect by a massive cage made of solidified iron, which keeps all who would attempt to bypass it in or out. All within must then succeed at a Will save each round or be paralyzed for that round. Those paralyzed by this spell become visited and traumatized by nightmarish visions, taking 1d6 points of damage per caster level each time they fail a saving throw.
