WC3 Armor System Confuzzlement

[Lohengrin]

I'm confused as to what happens when a unit's armor is reduced below zero.

If a 850 HP unit has 7 armor and loses 5, or if this same 850 HP unit has 20 armor and loses 5, the eHP loss is the same. But if this 850 HP unit has 3 armor and it's reduced to -2, then the eHP loss ceases to be the same. At least when you are using this formula: eHP = HP*(1+(armor*0.06)).

que?

Im not sure what u meant in the 2nd line, but from what i believe, the unit will take extra damage.

 

[Maker]

Damage increase with -armor is calculated with
2-0.94^(armor)

Where armor is |armor value|.

For example if your armor value is -4 then the damage increase is 2-0.94^4 = 1.219... -> about 22% damage increase.

I see, but I'm still not sure how you would calculate a unit's eHP using that information.

So I guess a better way to phrase my question is, how do you calculate the eHP of a unit that has an armor value of below zero?

In other words, how do you calculate how much physical damage a unit that has negative armor can take?
