The subject of this spell is bound in place, helpless, by the instant formation of half a dozen magical bands of darkness. He or she is aware and breathes normally, but cannot take any physical actions, even speech (the bands cover and restrain any part of the subject that might be able to move). The subject can, however, execute purely mental actions (such as casting a spell with no components). At the end of the duration, the bands fade away.

A winged creature who is bound cannot flap its wings and falls. A swimmer can't swim and will float to the surface. The bands can be destoyed before the end of the spell by a spell of 3rd level or higher with the [Light] descriptor, but the immobile subject suffers the same amount of damage without benefit of any sort of saving throw.

Material Component: A ring made of black steel.
