My players were looking to kill a Whiphid bounty hunter who had a datapad which they needed. They were alone on a landing platform, and he didn't know that they were enemies. So they decided to run over him with a landspeeder. (Fitting decision, he would have been hard to kill) They got in the speeder (not threatening, so no initiative yet) and then they said that they were going to run him over. The Whiphid got the second initiative slot. So the player in the driver's seat, acting first, tried to ran him over.
So, question 1: How do you assemble dice for running someone over in a landspeeder?
I decided it they would roll piloting-planetary (of course) vs. his coordination. I reduced the difficulty by one for easy it is to hit using a larger vehicle. I also spent a destiny point, as I didn't want to give them such an easy win.
And they got 1 success, 2 advantage, and despair after cancelling.
So, question 2: How does a speeder-running-over deal damage?
Using the rules for head on collision, I gave each a crit. Converting with the vehicle to personal scale is x10, generally, so poor Whiphid got a crit at x10. Dead.
And also, the despair damaged their speeder, and they suffered 8 wounds in the crash. (That put a PC over his wound threshold, so he lost a leg!)
Anyway, are there any rules that I forgot about? How would you have handled it?
