How does damage bonus work?

[Meridian]

Let's assume the Bow has 10 base damage (instead of 0).
Let's assume the Bow user gives it a damage bonus of 40.

What is the final damage spread?

a/ 0-100 ? (10+40 => 50 => 0-200% => 0-100) ...also, if this is the case, does the 0-200% get applied at the end or on both components separately?
b/ 40-60 (10 => 0-200% => 0-20 => +40 => 40-60)
c/ 10-90 (40 => 0-200% => 0-80 => +10 => 10-90)
d/ other?

I think a) is the proper answer. Might also be, a') (0-20)+(0-80), so 0-100 but more consistent. Need to ask Yankes, who wrote the code to be 100% sure...

[Yankes]

a) bonus damage is added to weapon power and rest of game logic follow normal rules of weapon damage.

What about stuff like hammers with +50% stun?

Is it:
a) calculate main weapon power (ie power + stat bonus), multiply by 50% and then subtract armor

b) calculate main weapon power, subtract armor, calculate actual damage, multiply by 50% and apply that extra

The first option is not really useful as the target's armor goes up, whereas the second always remains relevant.

[Dioxine]

b) is true for smoke & Stun weapons. All lethal weapons multiply the Stun damage caused by Fatal Wounds instead.

Oh? So that makes it sound like I shouldn't rely on weapons with +100% stun to stun things.. It sounded like it'd work well (do anything above 50% of health as damage and that would stun the target), and in fact it did work rather well

I couldn't find in the code where the game calculates damage dealt, or extra stun damage, so I don't really know how much stun it actually means. In UFOPaedia.org, it says 0-4 damage is dealt on per hit, but that's so low that even with +100%, I wouldn't expect to stun much of anything.

and in fact it did work rather well

In fact it does work rather well, and that's everything I need to know. It doesn't work reliably but it shouldn't.

How to make the weapon amplify the power of the ammo? That is, for the same ammo to have different strengths in different weapons
