Magical Damage vs Magical Defense

[JC Helas]

Can any of you give me the very common equation for this I was thinking that I would be better if I put this feature to my project game..

I already separated the physical and magical damage,, thanks to bribe.. by only using the brace,, hahaha awesome..

anyway about the physical they said that 1 positive armor will reduce damage by 5.7% hmmmm
but I wonder how 5.7% came when they use this equation (armor)*0.06/(1.0+0.06*(armor) hmmm

(armor)*0.06/(1.0+0.06*(armor) is the reduction factor.
The taken damage is 1 - reduction.

hp lost = damageAmount - damageAmount x damageReduction.

You also might have to consider negative damage reduction equation, if your project supports that.

each armor point provides +6% ehp, not 6% damage reduction.
