Least Invocation
1st Level Spell

You cause various bits of trash and junk in an area
- rotting garbage, old clothes, even dead animals
- to fly about and latch onto a target. The target
is entangled for 1 round per invoker level, or
until he makes a DC 20 strength check to escape.
Because this uses urban remains, it cannot be used
in wilderness areas.
