How exactly the damage depends from attack/defend ratio?

[Keneth]

Yes, you're right, it's not the ratio between numbers, just the difference. I've checked the damage script just now.

Here's how it works, first the game calculates raw damage checking for any applied effects like bless that give you max damage or outputting a random number if there are no such effects and multiplying it by the crit factor if applicable. Then the damage is reduced by resistance if any (max resistance is 95% btw). Then the damage koeficient is applied which is the unit's attack * (any racial bonuses (which are all percentile hence multiplication) + holy rage bonus) - target's defense. And lastly the damage is multiplied by any damage factors of the unit. So basically the equation goes something like this:

damage = rawdamage * (1 - resistance / 100) * x * dfactor

x = (1 + k * 0.0333) if k > 0
x = 1 / (1 - k * 0.0333) if k < 0
x = 3 if k >= 60
x = 1/3 if k <= -60

Uhhhhh... Could you translate the last please?
I perused the russian forum (I am not russian but know the language well) and they think there are 2 different cases:
1. If the attack>defense then each point (atck-def) gives +5% damage but not more then 200% bonus including the bonus from artefacts if any.
2. But if the defence>attack then the calcualtion is much more complicated. They say the damage dealt per point depends on the difference. The more difference is the less damage per point is dealt. So if the (def-atck)=1 point then the damage is reduced with certain percentage. But if the (def-atck)=11 points then the damage reduced by much higher percentage.
This seems logical as the devs try to prevent making allmighty armies from zillions of lowly units. And obviously if the hero is a warrior with high enough attack even the lowly peasants will deal huge damage.
BTW - I killed both Kraken and the Spider Queen using (among the others) 2 stacks of lowly thorns. And 700 thorns dealt much more damage then 100 royal snakes although I am just a mage.

It works exactly how I wrote it, this is not from the manual, it's from the actual script of the game's mechanism. Stepsongrapes has already put it in words, I just added the eqation and a few things that are also considered in the calculations. For every point of difference the damage is increased or decreased by 3.33% and maxed out at 300% or 33.3%.

My summation above, which appears to match Kenneth's formulae, is correct IIRC.

"Perhaps I should have clarified that each point that attack exceeds defense grants a 3.3% damage bonus. If defense exceeds attack, then it is a 3.3% damage penalty."

Caps of 200% bonus (i.e., triple damage or 1/3 damage) on either side.

I far as I've seen, there is no multi-tiered complex formula for either attack or defense, beyond the cap.

Hmmm... May the game balance be changed in the english version?

Will read more in the russian forum... yes... it seems the english version has the above mentioned formula which starts from version 1.6.2 and above. The russian patches are using this too so both versions are the same again.

Which is good...
