@legion3:
Do you read the sub shot in the battlebox of the target you are shooting at?
:?
Example if I target a AC/CV should I roll the battlebox and look at the first dice in the #1 slot or the dice sitting in the AC/CV # 4 slot?
You look at the first die and apply its result to the target you chose before rollling. Ignore the units listed on the chart.
@legion3:
Also how does a subattack work on a BB? Since the BB has the first shot, no damage ability. Does the subshot count as hit # 1 or is it simply a wasted shot?
Otherwise the sub attack against a BB gains you nothing.
A battleship can only ignore one hit per turn. The first sub hit would cause no damage, but it would expend the battleship’s armor for the turn, causing any subsequent hit on the same turn (whether from another sub or in general combat) to do damage. Thus, it is only a “wasted shot” if no further hits are scored on the battleship during that turn.
