Power Dive

 
Prerequisite(s): Str 15+, fly speed (average maneuverability)
 
Benefit: When flying, you can dive and land on an opponent to deal additional damage. Using this feat is a standard action, and it can affect only creatures one or more size categories smaller than you. To use this feat, make an overrun attack, but the opponent cannot choose to avoid you. If you knock down the target, you may make an additional slam attack (at the usual +4 attack bonus against prone opponents). The attack deals the base damage given on the table below for your size category plus 1 1/2 times your Strength bonus (rounded down).
 
Size: Base Damage
Fine: 1d2
Diminutive: 1d3
Tiny: 1d4
Medium: 1d6
Large: 1d8
Huge: 2d6
Gargantuan: 2d8
Colossal: 4d6
 
Special: If you fail in your overrun attempt and are tripped in turn, you are knocked down, and you deal the slam damage for the attack to yourself.
