A basic question that came up during a game on Saturday and, after studiously flipping through the book for five minutes, I couldn't find an answer.

How is the difficulty of a piloting check in hazardous terrain determined? Is the pool made up of speed/silhouette with the smaller of the two pools upgrading the difficulty dice to the appropriate challenge dice? For example, would a Silhouette 3 ship traveling at Speed 3 require a check using a pool of three red challenge dice?

Actually it would be 1 purple and 2 red. The Silhouette value is halved, rounded up.

So a TIE Fighter going through hazardous terrain at Speed 5 means 3 purple, 2 red.

Keep in mind, failure only means that the ship slows down by 1. Despair may mean a collision, and threat can also be spent to represent stress. It's not an automatic hit something and die... In fact, only really bad despair results might end up that way.

Pg 240.

Difficulty is equal to vehicle Speed or half it's Sil (rounded up). Bigger number is purple dice, smaller number is upgrades.

So a Sil 3 ship moving Speed 3, is going to have a difficulty of 1P, 2R.

You then add setback (black) dice to adjust for exact terrain difficulty.

Awesome. Thanks all!
