Suppose I shoot a full health Y-wing (2 shields) with Plasma Torpedoes. I roll two hits. They roll no evades. Which occurs?
1. Attack hits. Trigger Torpedoes, lose a shield. Then they take the two hits from the attack. Result: YWing is left with zero shield and one hull damage.
2. Attack hit. Defender loses two shields. Trigger plasma torps for no effect since no shields remain.
