Thanks for helping, yes I am looking for the "increase" as a ratio as given in your second formula

(100/(100 + (armor * .65))) / (100/(100 + armor)) *But you have it backward for what im checking*

And this is going to be different for every enemy you target since most chances they will not have the extact same armor.

I don't think it's safe to say this value stays pretty constant around 10% within a range of 60-250 armor.

Lets you the use a base, lets say its an AD Spell that does 500 damage before armor reduction and the enemy has 250 armor.

Plug in the numbers for the above formula but with the 500 raw damage and 250 Armor too. (and not backward)

(100/(100 + 250)) and (100/(100 + (250 * .65))) =  0.286 and 0.381

(500*0.286)/(500*0.381)

143/190.5

= .752

And (1-0.752) = 25% increase from 140 to 190.5 damage this is without the base armor or base damage changing.

Alot more then 10% increase in damage more then double at this armor level.

if you use the formula I gave (it's basicly simplified of above I think.)

(35)*[1-(100/350)] =  25% damage increase, it's the same thing number.
