Both the rules and the official FAQ state that when doing a Destabilization check you roll every die from every column with a blast at the bottom. These are referred to as the circuit dice.
The rules state that
Roll the circuit dice until either the Bomb explodes or the circuits have been passed, checking the following after each roll:
- If at least one 'X' is rolled and no blast, the circuits have been passed.
- If at least one blast is rolled, the Bomb explodes"
The way I read this is that you roll all the circuit dice together and keep rerolling until you EITHER get at least one 'X' with no blasts OR you get at least one blast.
The official FAQ on the other hand states that
The active player now needs to roll all the open circuit dice one by one until either a Blast or X symbol result is rolled to end the destabilization process.
A roll of X will successfully end the destabilization process, while a roll of a blast will trigger an imidiate explosion.
If all open circuit dice are rolled without one of these results the bomb does not explode...success.
So far we have been playing it by the rules as written but I wonder if the FAQ should be considered errata. The method in the FAQ obviously makes it easier to pass the check since each die at most will only be rolled once and since rolling an 'X' prevents the remaining dice from being rolled (snd possibly showing a blast).
If the FAQ is the correct way, then I assume that the player gets to choose in which order the dice are rolled. That way you can at least leave the red dice for last since they have two blasts each.
