The manifester can use
power points to boost his or her Strength, Dexterity, and Constitution modifiers as a free action. While the
duration lasts, the manifester can use
power points on a round-by-round basis to boost any or all of his or her physical
ability score modifiers (not the actual
ability score) by a number equal to half the
power points he or she expends for that round as a free action. The manifester doesn't have to boost an
ability modifier every round to keep the power in
effect-as long as the
duration lasts, he or she has the potential to boost his or her
ability modifiers on any round.
