eHP vs Resist/Armor

  • #1
    I am new to Diablo and new to DiabloFans forum.

    I have read quite a bit about D3 mechanics but I still have doubts and do not understand the above.
    I would like to ask some questions regarding the above topic.

    I am trying to built my char for survival and I read that I will need to add to the above stats.

    So my question:
    - when I upgrade 1 of my item, my Resist/Armor stat drop but my EHP increase

    For the above case, EHP increase, must I also increase resist/armor on the same item to be consider an upgrade?

    On a different topic, which are better or are they about the same?
    example
    - 800 AR and 5000 Armor
    - 1000 AR and 4000 Armor

    Bottomline, if I cannot find items to increase my ARMOR stat, can I upgrade my AR to compensate the ARMOR?

    Thank you.

    Try out d3up.com it will help you see how things work.

    As per your questions, AR is 1/10 of armor so you can treat 1000 armor like 100 AR. It's most optimal to keep these in even ratio with each other, so don't just stack one.

    EHP is a combinatino of your total life (HP) and total damage reduction (DR).

    Total DR is based on "DR from armor", "DR from resists", and "Other DR". Other DR are stats like "reduce damage from melee attacks by %". So, to answer your question, you want to increase BOTH armor and AR.

    10 armor = 1 AR if you have armor and AR at a 10:1 ratio. If you have 5000 armor and 800 AR, adding in 100 AR will provide more total DR than adding 1000 armor. If you have 2000 armor and 300 AR, adding 1000 armor will provide more total DR than adding 100 AR.
    OFFENSIVE STATS: 126K Unbuffed DPS • 183K Buffed DPS • 2.25 APS • +24% Movement Speed
    DEFENSIVE STATS: 1.07M Unbuffed EHP • 102K Life • 2,269 Life on Hit • 674 Life per Sec • 23.5% Dodge

    Either theres a mistake or i don't understand somehting :)
    When armor is lower and AR are higher (10:1.6 in your example) then adding armor should be stronger, because of the diminishing returns of higher resists, until the point when the ratio is 10:1 again.

    In your second example the ratio is 10:1.5, but you're saying armor is better this time.
    If im wrong i'd really like an explanation, cheers

    I wouldn't worry about the 1:10 ratio too much. While it's certainly "optimal" to keep them balanced, it's not always possible for a variety of reasons. Regardless of the "optimal" ratio, more is always going to be better, and your gold will let you get a lot more armor than resists, even if you violate the ratio, you will still be better off getting the armor or just more vitality/life %. A better way to analyze it is to ask, "How much % EHP increase do I get for X gold?" If you accidently eventually stumble on the magic 1:10 ratio, great. If not, don't worry about it.

    Thanks for all the replies.

    I have further read that found something like what unReality said.

    There are:
    Armor Damage Reduction = A%
    TotalArmor / ((50*(Creature Level)) + TotalArmor)

    Resist Damage Reduction = B%
    TotalResist / ((5*(Creature Level)) + TotalResist)

    Total Damage Reduction = 1-(1-A%)*(1-B%)

    Of course increasing both will definitely be better, but when you are put to a choice to increase ARMOR or AR, then you might want to whip out the calculator and see which is better for your total DR.

    The above definitely helps me, hope it will help others.
