How much does each enchant armor protect?

I am wondering how much each enchant armor scroll helps.

Like does it erase 1 pt of dmg, or some sort of percentage, or what?

it ups your p.def by a certain amount, normally 1 or 2, above +4 its like 3 or 4 per, afaik.

+1 p.def. From +4 on it's +3 but it also has a chance of breaking resulting in crystals of the item's grade.

There's probably someone else around here who knows the p.def formula, let's hope they show up :)

well its really all about lvl
if you have 5 +'s on you armor at 20 you would prolly get like 6 extra pdef
at 70+ with the right masteries +1 could be as high as 5 extra pdef

Mastieries is an + addon at the end of the formulate, it dosnt mater what armor you have as it's not an % increse it's add the same to whatever.

it never gonna be more hten 2 or 3 P.def added for an +1 in the future for all classes.

You can read the formula there.

The difference gets bigger not with masteries, as ple pointed out, but with your buffs status and level. :D
