Interesting. I think the speed and Dex loss makes sense as well.

Slow Petrifying Gaze (Su): 30 feet, Fortitude DC X negates. On a failed save, the victim must continue to save each round thereafter and is slowed (as the spell) and takes a cumulative 10-foot penalty to speed and a -2 penalty to Dexterity, but gains a +1 enhancement bonus to its natural armor as its skin begins to harden. A successful save after the initial save does not negate the effect, but prevents any further penalties and eventual petrification. If the target fails three consecutive saves, the victim is turned to stone permanently. The effect can be reversed by a stone to flesh effect at any time. If used before complete petrification, no saving throw is required to survive the transformation. The save DC is Charisma-based.
