- A reference guide and manual in Russian for Heroes 3.

The damage from ranged towers is affected by 3 factors: the Air Shield spell, petrification of the target, and the presence of a secondary skill or armor specialization on the attacking hero. All these factors should reduce damage, but they increase it – this is a bug.
There are no questions about the first factor (it is also mentioned in the physics engine), the second one is not frequent enough for basilisks or medusas to emerge from the castle and petrify the enemy, but the third one – a hero with expert armor does not receive a 15% reduction in damage from towers, but rather a doubling of the damage. The only question is that this bug does not always occur (although I once saw it mentioned in descriptions). I check on one PC – it exists, on another – there is not even a hint of it. The pattern is unclear. It does not depend on other factors, but when Air Shield and the armor skill are applied simultaneously, only one of them takes effect. That is, apparently, any of these factors can trigger the doubled damage from towers.
So, the question is – in what situations does the negative effect of the armor skill manifest itself, and how can this be dealt with?
