How exactly % reduced armor pen works?

Who remembers how it works exactly? If for example I got 4 k armor and 10% reduced armor pen, does it translates to 400 armor? Or it depends on attacker's armor pen? Or how does it works?

I searched for "warhammer online combat formulas" and got
viewtopic.php?t=971 this link. It's old and covers all parts of the combat formula, but I have high confidence it is still useful.
TLDR: if you have 4000 armor and enemy hitting you has 50% armor penetration, you apply your 10% reduced armor pen resulting in an attack on you that ignores 40% of your armor. You'll have to read more in that link for more info, but that's the basics.

Correct.
Just a reminder to anyone looking at armour formulas that "armour penetration" is its own unique thing and should not be additively combined with effects that ignore or by-pass armour.

So for tactics that ignore 50% of enemy armour, how would an additional 20% armour pen from WS apply?

Ignore 50% armor, then pen % of remaining armor, I believe.

Pretty much.

Based on this it should work like this:
Code: Select all
armor = armor from gear - static debuffs + static buffs
armorEffective = armor * (1 - (<armor penetration%> - <reduced armor pen%>))
So if you had 4000 armor, 10% reduced armor pen and the attacker had 0 WS and other armor penetration it would be 4400 effective armor.
Code: Select all
armorEffective = 4000 * (1 - (0 - 0.10)) = 4000 * (1 + 0.10) = 4000 * 1.10 = 4400
I'm not sure if the implementation on RoR is different though.
