Wing Bounce

FEAT 4
Activity 2 actions
Archetype Winged Warrior

You rush forward, flapping your wings for a bit of lift, and can use that momentum to knock down a foe. Leap, and if you land within melee reach of at least one enemy, you can attempt to Trip that enemy. You don't need to have one hand free. If you successfully knock the target Prone, you can Leap again. If you have a fly Speed, you can Fly instead of Leap.
