If some tool won't work for some job, just increase the power level. What could possibly go wrong?
GM: What are the rest of you doing while Luke and Leia are chasing troopers?
Chewbacca: I wait quietly for them to return, while pondering our plight.
Han: I fortify the area! By chopping down trees and erecting poles.
C-3PO: I initiate an uplink to Admiral Ackbar to report our status.
R2-D2: I roll around the clearing to level up my forest movement. Trust me, I need it.
Han: Spiked poles that stop bikes.
Han: A bit like the trees.
GM: What are you chopping down trees with?
Han: A blaster?
Han: Okay, fine. I see that plan won't work. I'll get an ion cannon from the shuttle.
R2-D2: An ion cannon just to shoot bikes?
[SFX]: < whrooop poppy bababing ping >
Han: No, to make the spiked poles.
