Hello,

can some one explain why I shouldn't fire all of my ships weapons every time I am trying to destroy an enemy ship? Yes i do only 1 Critical Hit but that hit has a good chance to exceed the ships armor whit enough damage to destroy it, in one single shot! that don't make exciting battles...

Critical Hits are the best way for a weaker vessel to take on a stronger one, particularly if the other ship is undertaking Evasive Maneuvours, or it has a lot of shields. For the most part there's no real reason not to combine salvos in a standard combat.

Well it depends on the weapons and the target. A ship with a macrocannon and a lance. Is going to fire the macrocannons to take down the shields. The damage after the shields isn't often enough to damage the ship, but lances ignore armor and crits really well. The macrocannon paired with a lance can disable an opposing ship in a few rounds.

If your ship has 2 macrocannons then you generally always want to fire both to together unless your target has weak armor. If the target has weak enough armor, your crit chance is good, and you got good BS then the extra crit might be important enough to lose a little damage.

If I understand correctly, the chance to score a crit is given per weapon component, and is a separate stat from its strength.

What if one combines the fire from two different macrobatteries, with different crit-chances? Does the lowest count for the salvo?

On a different matter, but still close enough to be related to the topic:

What are good ways of increasing the chance to score a crit? Can the Rogue Trader perform the "Put your backs into it" extended action to add +5 to the BS test as well as his Exceptional Leader Special Ability (+10 to any test) free action?

Lowest crit rating technically applies, but you roll for each macrocannon separately.

Put Your Backs Into It, Lock On, Exceptional Leader, various weapon Components.

Aha, I was under the impression that you made one single BS-roll for the salvo. That is not the case, and I'm uncertain why I thought so in the first place
