BCF: Dogfighting
At this level of mastery, your ability to weave through combat as is as carries over to anything you have in hand.
You gain the Evasion common feature.
Additionally, the benefits from this and your weapon specializations (all Specialization Passive/Critical effects) are kept and applied to your Mounts and Vehicles.
Evasion
You've learned to move quickly to avoid explosions, dragons' breath, and worse.
When you are subjected to an effect that allows you to make a Reflex Save to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.
.....It's surprisingly common.
