For the dive attack, were we considering using one or more of these?
Dive (Ex): Once per hour, a fire falcon can move ten times its normal speed (900 feet) when it makes a flying charge attack from a higher altitude than its target.
Dive (Ex): A flying sword archon can make a diving attack, if it has 100 feet of clearance between itself and its target. If this attack is successful, the bite attack causes 2d10+9 points of damage. While diving, the archon gains a +3 circumstance bonus to its Armor Class due to its high speed.
Deadly Dive (Ex): When a crow's-nest dragon dives at least 30 feet and makes a successful bite attack at the end of the dive, it deals an extra 1d4 points of damage.
Swoop (Ex): Alguduir gain a +2 attack bonus when diving from the air to attack a land-based or underwater opponent.
Swoop (Ex): A noctral can execute a swoop attack that is similar to a charge action in all respects, except as noted here. The noctral must fly toward its target for a minimum of 50 feet in a straight line. If the swoop attack succeeds, the noctral can attempt to grapple the target without provoking an attack of opportunity or deal double claw damage (4d4+8 points) instead.
Swoop (Ex): If a flying hawkdragon charges or dives at a foe, it can make a full attack with both claws and its tail, dealing double damage with any attacks that hit. If either of its claw attacks hit it can attempt an eye gouge (see above).
