Effect: Area burst 1 within 10. The burst creates a zone that lasts until the end of the encounter. Whenever a creature on the ground enters the zone, it must succeed on a saving throw or fall prone. When forced movement moves a creature into the zone, that forced movement increases by 1 square, and creatures in the zone take a -2 penalty to saving throws to avoid entering hindering terrain.
Special: Recognizing the zone requires a hard Perception check.
