Gain the Advantage
We use this house rule.
Gain The Advantage (CSR)
Pilot Only Maneuver
Requirement: Speed 1+
Target one starship or vehicle in Close range and make an opposed Piloting check against the starship or vehicle’s pilot.
Upgrade the check for each point of Speed your starship or vehicle is travelling faster than the target, and downgrade the check for each point of Speed your starship or vehicle is travelling slower than the target. Add Boost or Setback die as normally determined by the starship or vehicle’s Handling rating.
On a successful check, combat checks from your starship or vehicle against the target are upgraded and you may choose the defense zone targeted.
I see you changed it to a maneuver which makes sense to me, but your description doesnt say how long the effect lasts. I believe in the beta it lasted until the enemy ship countered you, which makes it really useful...but it was nerfed and changed to only last 1 round in live
