Do I understand damage reduction?

[Kep]

I build tanks in basically any game that allows for it so this is nigglin' my noggin a bit.

From the codex: "Damage Reduction functions as a percentage increase in effective Health. If you have 20 Armor and 200 HP, then your effective HP against physical damage would be 240."

Based on that example the game is saying 200/(1-X)=240 instead of 200/(1-0.167)=X, right?

 

[The Observer]

The exact formula is damage received = raw damage * 100/(100+relevant mitigation stat).

Effectively, every 100 armour gives you an extra healthbar vs. physical damage.

Thanks much, that lines right up with what I was figuring. It just threw me off but good since most games will give you a percentage and leave you to figure out survivability for yourself.
