Jump 5 ranks, WIS 13, base attack bonus +6,
The Raptor School feat enables the use of three tactical maneuvers. Eagle's Swoop: To use this maneuver, you must charge a foe or jump down on your enemy from at least 10 feet up (see page 77 of the Player's Handbook). Make a Jump check as a free action immediately before your next attack. Prior to making the roll, determine the DC of the check: either DC 15 for a chance to deal 2 extra points of damage or DC 25 for a chance to deal 4 extra points of damage. If you fail this Jump check, you miss your target, and if you fail this Jump check by 5 or more, you fall prone in an adjacent square. Falcon's Feathers: To use this maneuver, you must be wearing a cloak. As a standard action, you can whip the cloak around you in a distracting fashion. Make an attempt to feint in combat (see page 68 of the Player's Handbook), using your base attack bonus instead of your Bluff modifier. If you succeed, your target is treated as fl at-footed for the next melee attack you make against it. Hawk's Eye: To use this maneuver, you must spend at least 1 full round observing your foe. While doing so, you can take no other actions. The next melee attack you make against your foe gains a +2 bonus on the attack and damage rolls for every round you have just spent observing the foe, to a maximum bonus of +6 (for 3 consecutive full rounds of observation). If the target of your observation attacks you while you're observing, or if you don't make the melee attack within 3 rounds of the end of your observation, you don't get the benefit of the feat.
