Keywords on attacks add to the entire take pool, as it doesn’t matter what dice make hits. If you add DLT to the stormtroopers attack pool, and both red dice blank out, the white dice will still get impact against armor.
all of this is true for except 1 keyword, “High Velocity”. It only counts on the dice for that weapon and not the attack pool. In fact every weapon in that pool must have HV to be unable to dodge. Why?? why is this the only keyword in the game that is lost if other weapons are added to the pool?
