Good Afternoon,
One further clarification if you can.
Always replace before modifying. In this case, the weapon's Attack Value would remain 4 because it's replaced before the ship's PWV is modified to 6. When new replacements and modifications are introduced you always recalculate so the order of effects does not matter.
If this is the case would not the ship's PWV be increased to 6 during the activation phase?
Based upon a ruling for dispersive armor it would appear that the Attack Value is set when the weapon is utilized.
2) If the attacking ship is using a secondary weapon that uses the ship's primary weapon value for it's attack value, is this value adjusted due to the effect of Dispersive Armour?
2) The Attack Value of the weapon is calculated each time the weapon is used. If my normally 5 PWV is changed to a 4, the weapon's Attack Value is calculated as a 4, unless something like printed Primary Weapon Value is specified.
Therefore; if I am reading this correctly:
Beginning of Activation Phase: Merridor "Increase this ship's Primary Weapon Value by the same amount this game round."
Combat Phase:
1) Utilized Federation Torpedoes to attack and the weapon checks the value of the ship's PWV; in this case it would be 6. Then it adds +1 making the value of the Federation Torpedoes 7 (Replacement).
2) Modify: Donatra at Range 1 yields +1 Attack Die and Tactical Station Discard yields +2 Attack Dice for a total of 10 Attack Dice.
Thanks in advance,
