As the links of chain in your hand dissipate
to feed the arcane energies of your spell, a
multitude of ribbonlike shadows instantaneously
explodes outward from an indicated
point nearby.

Creatures in the area that fail a Will
save are entangled and unable to move.
Breaking free of a shadow binding
requires a DC 20 Strength check or a
DC 20 Escape Artist check, taken as a
full-round action.

Material Component: A few links of
iron chain.
