How exactly the damage depends from attack/defend ratio?

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.

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.
