Let's say I have a weapon with 1000 ballistic damage to both ships and buildings... a special that gives +50% ballistic damage, and a second special that gives +50% building damage.
The damage to ships seems easy to calculate, it's simply 1000 x (1 + 0.5) = 1500.
However, when it comes to the building damage, does the bonus building damage only apply to the base damage of the weapon, meaning that bonus ballistic damage is only used for calculating damage to ships? Or does it all stack together? And if it does stack, is it additive, or multiplicative?
A. building damage = 1000 x (1 + 0.5) = 1500?
B. building damage = 1000 x (1+ 0.5 + 0.5) = 2000?
C. building damage = 1000 x (1 + 0.5) x (1 + 0.5) = 2250?
