Is there an EHP calculator for D2, I can only find ones for D3 online.

Or could anyone help me with a formula that only factors in Hp/Armor, and assumes all other variables are the same. Trying to compare items, but can't tell how much EHP I'm losing vs damage.

reason for that is that armor works totally different in both games:
in D3, armor decreases physical damage (similar to damage reduction in D2, which is just a strange wording for physical resistance)
in D2, armor just decreases the chance that you get hit by attacks. the chance to hit depends on your armor (which is called defense in D2), the opponents attack rating and the levels of both characters. see here for more details:

which items?

Curious Effective health of enigma vs fort on a 20 defiance/20 holy shield paladin. Need to factor in HP gain from enigma strength, combined with using it in a lower str armor, vs a higher strength armor with fort and losing the 70 str in enigma that could go vit.

The life base on level for fort does not benefit from BO. ~142 to life

Enigma has ~70 to strength. which would be 210 to life. This would receive benefits from BO. So the 210 could be 350-500ish.


Fort gives you chilling armor though which is more defense. I'm not sure if this will be needed if you already have shout, defiance, and holy shield. The level of shout may be important here. If shout is only level 6-10 vs level 40-50 it makes a big difference.

Further, Which enemies are you fighting? if it's basic mobs you would need less defense to get them to %5 hit chance vs someone running ubers or dueling.

I think the answer is do you need teleport? If no then use fort. If yes then use enigma.


Enigma is insane and hard for it to not be BIS on any char.

D2 is much more complicated than d3.

To factor in how defense affects your eHP, you need to know your opponents level and how much AR they have.

But even that’s a simplification assuming you aren’t just melee Vs melee

for example, enigma is going to give you more eHP than a higher defense armor vs most opponents bwcwuse the ability to teleport will allow you to take less hits.

Anything you know about d3, does not apply to d2. As d2 is vastly more complicated than d3.

The term eHP is only typically used for zons due to their dodge/avoid/evade + 75% block mechanic. A 3500 HP zon has a 92.2% chance to avoid being hit by a melee attacker, that as capped AR to Def ratio to them. Giving them an eHP of roughly 48,500.genenralt speaking, a melee attack won’t hit capped AR to Def ratio (thus giving them a 95% hit rate) vs a zon. Thus lowering their hit rate. And thus raising zons eHP even more.


The 92.2% block is derived by:
(1-(block rate)) x (1-(dodge %) x (1-(enemy miss rate)
Where common values for the following are:
Block rate = 75%
Dodge = 67%
Enemy miss rate = 5% (At capped AR vs Def ratio, miss rate is floored to 5%. Or another way of expressing this phenomenon is that the opponent has capped hit rate of 95%)

Makes sense, still is there any rough estimate people use for EHP in terms of just health and armor in a purely melee situation? Something like (1 life = ~15 Defense) ?

No. As it’s completely dependent on your Defense value vs your opponents AR. And you genenralt will not know your opponents AR.

Your opponents Hit rate is a ratio of your opponents AR vs your Def.

Well assuming AR is the same in all situations, isn't the only variable for EHP health/armor?

For your opponent to cap their hit rate vs you (where cap is 95%), they need 20x as much as AR as you have defense.

Without knowing both your defense and your opponents AR, it’s impossible to know how much value you get from 1 defense

And then assuming you know your opponents AR, you also would need to know your opponents damage values to know how much 1 defense equals in terms of life.

Long story short, the term eHP is a pretty useless term outside of zons.

D2 is much more complicated and that term does not work with how d2 works mechanically.


Where melee = zeal Paladin , concentration barb, fury druid, jab zon
