Immobilize

Immobilized creatures are unable to move and are considered flatfooted. This effect cannot be resisted.

Opposite of the effect description while immobilized, a creature's modified dexterity score is overridden to 3 and is unchangeable. The creature's dexterity modifier, however, is not similarly overridden to the corresponding value (-4) unless the dexterity score is changed in any way after the application of immobilize. Once the immobilized effect expires the modifier are restored.
