How much armor is equivalent to 20% physical recistance?

[SimonZes]

Anybody know?

[Aleera]

Armor stops anywhere between 50% of the armor value to 100% of the armor value for non armor piercing damage.

So for a attack without any armor piercing, armor would need to be 40 to be 100% to lower by 20% all the time. But with luck you only need 20 armor.
On average though, 20% physical resist is equal to roughly 30 armor vs non ap.

Goodness that is a tough calculation... But AROUND 30 Armor

[DarkFenix]

About 27 armour. Armour gives a random % reduction between the full number and half of it, so 27 armour gives an average reduction of ~20%. Of course, that comparison is rather moot, since AP damage ignores armour but doesn't ignore physical resistance, and pretty much everything has at least some AP damage.

Not everything has AP dmg do. So that is why I am asking. Was wondering just how much 20% physical recistance that alot of daemon faction unit has has compared to a unit with just alot of armor. Like bloodletters vs chaos warriors. Was just curious so not moot at all I would say.

on average it equates to 26.7 armor
but you have to take it as an average since armor is variable while resistance is always just its %

The damage reduction provided by armor is on average 75% of the armor value (it's a random number between half the armor value and the armor value, uniform distribution). The calculation is thus 20 / 0.75 = ~26.67 armor.

It looks like some helpful peeps have already answered your question, which is very nice of them.

Almost as nice as it would be of CA to give us Hotseat mode.

Very few units don't (I actually can't think of one off the top of my head). Even most non-AP units will have, say, 15 normal damage and 3 AP damage or something. AP units simply have the balance of their damage types skewed massively in favour of AP damage.

Every unit has AP damage, even zombies have 2 AP damage per attack and as far as I know, they're the weakest. Even peasant archers have 3 melee AP.

I assume the OP thinks unit's without the icon of armor piercing have none. But everything has some AP damage. Ethereal unit's in game 3 will have no base damage though, full AP.

^as said above, everything has at least a bit of AP damage (only spells can have 0% AP) and therefore answering 26.67 armour is plainly incorrect. The lowest AP percentage have "weak against armour" and as you know there's not that many units with this mention in the game. Most units have between 25 and 50 % AP afaik. And 20% physical resistance is going to remove 20% of that damage as well. Assuming a 40% AP in average, you can redo the calculation with the idea that 20% physical resistance remove 20% of the total damage which is then identical to 33% of the non AP damage rather than 20%.

so 33 /0.75 = 44 armour rather than 27.

And bear in mind that generally, the scariest enemies that threaten your units the most are heavily AP. So while the number I just took above of 40% aims to be relatively fair, it is in no way representative of how much 20% physical resist is valuable since it removes 20% of the damage from the scariest enemies, which 44 armour... does not. Some non ehtereal enemies have up to 80 % AP, in which case having 20% physical resistance is better than having ... 260 armour.

Also, armour gets lowered by fatigue by up to 30% for exhausted units iirc . physical resistance do not and stay consistant.

So 27 armour is just plain wrong. Counting fatigue and AP, you probably can consider something closer to 50+ armour tbh (unless the unit has perfect vigour obviously, but even then count at least 44).

[Ashardalon]

the scariest enemys have magical attacks
so they have 100% ap to physical resist

[Caramel_Clown]

It depends on how much armor unit has already. If it's a unit with 0 armor then around 33. Ingeneral physical resist is quite a bit overrated. Yes, it does negate AP, but armor also block magic damage from both spells and magical attacks. So having lots of armor is generally better than very low armor and a tiny bit of resist.
BTW, formula is as follows. Chance to block non AP damage is equal between half the armor value and full value. So, for 50 armor it's between 50 percent and 25 percent. You can calculate the average yourself.

[Cyiel]

Physical resistance also decrease piercing damages but Armor doesn't do that. So it depends alot about the base damage/piercing damage ratio.

That's the kind of answer that can completely mislead players who don't understand how it works. :/
Magical damage are just not reduced by a physical resistant and... that's it. Magical damages are still reduced by armour (and Magical Resistance of course).

[Ashardalon]

no the thing is, yes every attack has a tiny amount of ap damage
letting them ignore a little of the armor
but if they have any form of magic damage they 100% ignore all of the physical resist
as mentioned ghosts will have 100% ap damage and thats special and scary, but its rarely mentioned that ghosts also have magical attacks wich gives them 100% physical resist negation
yet people dont think thats significant
the scary scary 100% ap doing the exact same thing to armor as any magical damage does to physical resist

Yes I know that almost every unit do a little ap damage but that seems negligible. But what I am trying to figure out is for general use. Who would take the least damage a unit with say > 100 armor or a unit with almost no armor and 20 % physical res. Where is the sweet spoot! :-) But as you all pointed out there is alot to to consider to get an answer for this.
