Awesome post if you havent read it already great for players.
http://armadagaming.com/showthread.php? ... ive-HealthIf you dont want to read it basically shows that there is a 1/10th ratio for armor vs natural resistance.
Also armor reduces elemental dmg as well, and all resistances reduces attack damage as well.
So lets say i have 1000 armor and 50 fire resistance. Since my armor/10 = 100 my fire res needs to go up to 100 before armor would be useful there.
Ugh i hope that wasnt too confusing.
