It is only a short time before you reach the access point that leads into the underwater caves and toward the planet's core.
Dive dive dive! You sense some anxiety from King Evand as the water rises outside the craft's windows and swallows the submarine. Even the clean blue waters of Naboo dim the light as you descend, and soon you are moving into the mouth of a great submerged cave.
"Are you sure you can drive this thing?" King Evand asks.
The cave network branches off in several different directions, but a combination of your Jedi senses and, more importantly, the maps provided for you help you navigate in the right direction.
The issue here, then, is time! Some routes are easier but slower, while others are decidedly more difficult but quicker for getting to the Gungan city. Also, how fast you are driving the submarine.
So I will need a plan- how fast are you going and what route do you want to take?
Combined with Dexterity, that is a pool of 7 dice, on which you roll two successes as you zoom along through the submarinal caverns. You aren't pushing yourself so you spend some time navigating the caverns, going deeper and deeper into the planet's crust.
The sensors blurt out a warning signal, and you feel uneasy.
The Kings Guard is a better pilot than I am, no?
Denz will shunt power back into the engines and attempt to shake the giant fish-thing off.
Wait did you say ray-shielding? Those would be impractical on an underwater craft, particle shields would be more effective and helping keep the crushing depths at bay, and even protect repel solid objects. Who designed this thing and decided to give it ray shields is an idiot. -Denz thinks.
Trozen is about equal. You do not have room to switch pilots.
The submarine has particle shields as well, but an electrified hull would be impractical and fry the entire system.
It will be a Pilot roll to throw on the thrusters and try to break free. Three successes is enough as the craft's propulsion steams the water around it and shoots into the creature's mouth. You jet free!
The monster isn't giving up so easily. Your sensors pick it up coming after you.
