Prerequisite(s): Investigator 7th level

Benefit: When the investigator deals damage with studied strike, the opponent must succeed at a Fortitude save (DC = 10 + 1/2 the investigator's class level + his Intelligence modifier) or be slowed by the crippling blow. A slowed opponent's movement speeds are each reduced by 5 feet (to a minimum of 5 feet) until the creature is healed through the application of any spell that cures hit point damage or with a successful DC 15 Heal check. Multiple slowing strikes stack, to a minimum of 5 feet.
