DESCRIPTION
You concentrate the force of gravity in an area, causing it to begin crashing down on all within it and crushing creatures and objects to the ground, dealing 1d4 points of bludgeoning damage per caster level (maximum 15d4) to all creatures in the area when the spell is cast who hit the ground. Affected targets weigh twice as much as normal, can move only at half speed, jump only half as far as normal, can lift and carry only half as much as normal, and are staggered and knocked prone. Any flying target has its maneuverability worsened by two steps (from good to poor, for example; minimum clumsy) and plummets to the ground unless it succeeds at a DC 25 Fly check to remain in the air. Freedom of movement negates the effects of this spell.

A successful Fortitude save halves the damage taken and negates the staggered condition and are not knocked prone.

Regardless of a successful or failed Fortitude save, the zone of concentrated gravity remains until the spell ends or is dismissed.
