This spell reverses gravity in the spells area, causing
all unattached objects and creatures within it to fall upward and
reach the top of the area in 1 round. If some solid object (such
as a ceiling) is encountered in this fall, falling objects and
creatures strike it in the same manner as they would during a
normal downward fall. If an object or creature reaches the top of
the area without striking anything, it remains there, oscillating
slightly, until the spell ends. At the end of the spell duration,
affected objects and creatures fall downward.
Provided theres something for them to hold onto,
creatures caught in the area can attempt Reflex saves to secure
themselves when the spell strikes. Creatures who can fly or
levitate can keep themselves from falling.
