Editing Damage (section)

==== Secondary skill factors – variables R<sub>2</sub> and R<sub>3</sub>====
Similarly to the variables I<small>2</small> and I<small>3</small> variables R<small>2</small> and R<small>3</small> denote how [[Armorer]] and specializing in the skill affects the value of final damage. The reduction due to Armorer is not dependable on the attack type, but is the same for both ranged and melee damage. R<small>2</small> can receive values 0, 0.05, 0.10 or 0.15, respectively indicating that a hero does not posses the skill, has it on basic, advanced or expert level. The three heroes with an Armorer specialty - [[Mephala]], [[Neela]] and [[Tazar]] - increase the effectiveness of Armorer secondary skill by 5% for every level. Thus, as can be seen from the following formula, they double the effectiveness of the Armorer skill when they reach level 20:

<big><code>R<sub>3</sub> = 0.05 &times; Hero level &times; R<sub>2</sub></code></big>

Armorer has two unexpected side effects. First, heroes with Armorer take extra damage from [[arrow tower]]s. The damage reduction is reversed, as if the sign within the parenthesis would be plus instead of minus. Second, damage is reduced by 1 if creatures from a hero with Armorer take an amount of damage that is exactly an integer value. Thus, if 100 [[Peasant]]s attack a stack of Peasants commanded by a hero with basic Armorer (and the ADD is 0), damage is not 100 &times; 1 &times;(1 - 0.05) = 95, but 94. If the attack had instead been performed by 99 Peasants, the damage would be 99 &times; 1 &times;(1 - 0.05) = 94.05, which is not an integer value and therefore rounded off in the usual way, that is, to 94.
