Damage Formula?

[Boon]

Im sure i saw it somewhere but i cant seem to find it.

Does anyone have it? Im asking mostly because im curious as to how ammo mods work.

[Urukhai]

I may be wrong but from what I remeber I can explain you.

So...
I'm wielding a regular avenger minigun,  2 BRDs and one MRD

I see Boon under psycho and beer and all thoughnesses in CA MK2 with 75% dmg resistance, who is standing 25 hexes away from me, I'm aiming him and start shooting.
Probability of hitting the target: I forgot the exact formula but nevermind

If I hit you with 14 bullets of 5mm AP:)

minimal damage of an avenger is 12 maximal 15.

lets calculate the minimal damage: 12 + 7 (7 brd + brd + mrd)
19*14 = 266! but lets not forget, 5mm AP have 2/3 dmg modifier and -35% target resistance
I have to modify my damage because of AP ammo: 266*2/3 = 178!
But you are a fucking tank, so... lets calculate your resistance 75 - 35 = 40%
Now, I have to put away 40% of 178 = 107 on minimal damage (but don't forget that you have adrenaline rush I don't know how it works exactly after)
On maximal damage you will get 22 * 14 *2 / 3 = 205 - 40% = 123

So, If you are without adrenaline rush and any dermal implants nor a buffed CA. You will get in your face between 107 and 123 dmg
What about critical hit probability, I cannot tell you, because I don't know how it works, and it's better so !

I think I answered your question.

[Kaaon]

you forgot DT

[Urukhai]

yeah, damge treshold,
your Minimal damage you do - DT (the little number before your resistance in inventory when you are watching what armor you are wearing)
and olny then you calculate your percentage. So it must be lower.

[Boon]

Yup, that answered it all right, though i have another question.

I was fooling around with JHP and Finesse and it seems they can push the targets resistance to 100%
(which wiki says 90% is the cap) thus doing no damage.

Is 100% resist the true cap?

Say we're out in the wastes.
You're drugged out with CA and Avenger with 90% resist.
Im here with a jacket, finesse and 10mm pistol/AP rounds about to bring the pain.

Would i be up against:

Finesse 30% + 90% = 120% - 35% AP = 85% Resist
or
Finesse 30% + 90% = 100% - 35% AP = 65% Resist
or
I'm wrong about finesse and it DOESN'T exceed the 90% cap, thus:
Finesse 30% + 90% = 90% still - 35% AP = 55% Resist

[Urukhai]

I think that it's the first formula 

I tested before. No dmg happened always, when I was shooting with JHP ammo or when I used finess on a full tank. Just tank your self up to 75% and go farm Enclave or BoS. Stay one hexed in front af avenger minigun. The three first shots will be for no dmg, cuz these mobs are using JHP ammo

nope, they have AP ammo loaded defaulty, it was changed 3 months ago

- Changed default ammo type from JHP to AP for some weapons,

[Urukhai]

Omg I haven't farmed them for so much time xD

A part of combat.fos:
