For example, the Hunter´s Surprise, says nothing about which action uses to be activated.
Hunter’s Surprise (Ex)
Benefit: Once per day, a rogue with this talent can designate a single enemy she is adjacent to as her prey. Until the end of her next turn, she can add her sneak attack damage to all attacks made against her prey, even if she is not flanking it or it is not flat-footed.
Same thing with this other EX
Redirect Attack (Ex)
Prerequisite: Advanced talents
Benefit: Once per day, when a rogue with this talent is hit with a melee attack, she can redirect the attack to strike at an adjacent creature with a free action. The creature targeted must be within melee reach of the attack that hit the rogue, and the creature that made the attack against the rogue must make a new attack roll against the new target.
So, which type of action we must make to activacte those tow abilities above??
