I have a simple question that I haven't been able to figure out... How much HP does vit add? Is it a constant value or does it scale with your vit or other numbers?

Btw, really good read. I've always been wondering how armor and resist values are calculated into damage reduction.

As for the post above saying how wizards can tank better...

1 str = 1 armor

1 int = 0.1 resist

3000 armor = 2x hp

300 resist = 2x HP.

I guess you can figure the math from here.

From what I understand, vitality adds life like this: Until level 35 vitality gives you 10hp. After lvl 35 it goes up by 1 every level, so at level 60 it adds 35 HP.

Or expressed this way:

IF ( Level <= 35 )

HP = Vitality * 10

ELSE

HP = Vitality * (10 + (Level - 35))

Of course your actual HP takes into account other stuff like +%HP and what-not.

i tried your flash link to see what I need more of but no matter what I do, it says I need vit...

even at 0 armor it tells me to value vit more..

whats the point of that java program?

Sorry I think I may have poorly explained what that app does. The bar chart (which I assume you're talking about) shows how much effective health is increased by one additional point of vitality or one additional point of armor. Armor will basically always be lower than vitality, but items have more armor than vitality on them. So lets say it shows vitality adds 5 EH and armor adds 1 EH. The relative weight is 1 vitality is equal to 5 armor. So when evaluating two gear choices. Take their vitality attributes and multiply them by 5, and their armor attributes (multiplied by 1) and add those two numbers together. Then compare those values across two pieces of gear and you get whichever one is better.

For example, if your ratio is vitality = +5 and armor = +1

Gear piece 1: 10 vitality and 100 armor (10*5 + 100*1 = 150 EH).

Gear piece 2: 9 vitality and 110 armor (9*5 + 110*1 = 155 EH).

So the first piece adds 150 effective health and the second piece adds 155 effective health, so gear piece 2 is better (defensively).

Also don't live your life by these charts. It doesn't take into account barb's natural res, block, dodge, and so on. It's just good to get a feel for things.
