Effect

When you cast flux density, choose rise or sink. If you choose rise, each target ascends 10 feet per round, or if you choose sink, each target sinks 10 feet per round; this movement doesn’t provoke attacks of opportunity. In addition, each creature must attempt a Fortitude save each round it’s moved by this spell; a failure causes the creature to gain the flat-footed condition and to take a –2 penalty to attack rolls until the beginning of its next turn.
