How does accuracy vs evasion work?

I've been wondering what the formula is to calculate how many hits you will land against a target using your accuracy and their evasion.

Example: I have 3500 accuracy and my enemy has 4000 evasion. How often would I hit my target?

    There is an unconfirmed chance to hit equation here:

    So I calculated it and it shows about .0081 hits... but thats out of what?

    And is that a ratio of how often he will hit or miss...?

    So many missing things.

    I'm not sure why you are calculating hits since none of the formulas in that section calculate that.

    Try again with this
    chance to evade = 25 * target evasion / ( attacker accuracy * attacker level + 25 * target evasion)

    Sorry Asterelle I edited it after you quoted me b:chuckle

    But what is missing is op's attack lvl.

    Then we can calculate it better.

    I do wish u were in Lost City where my main is. I learned a lot from u there. b:kissb:victory

    It says "attacker level" not attack level. In the OPs example he is the attacker and you can tell from the avatar he is level 100.

    it doesnt matter how much eva or accuracy got u can still get hit or miss alot.
    i can get 9k accuracy on my barb and still miss alot on a low lvl char or arcane user.
    its just luck based.. evasion has been sorta broken forever.

    Simple miss look.. I was multitasking a lot...
    but either way this is what I came out with:


    25 * 4k / ( 3.5k* 100 + 25 * 4k) = 100k/(35k + 100k) = 100k/135k = .740740etc....

    So the chance to evade is .740740etc.....

    Hummm so does it mean the mob will have only .740740 chances to evade the attack?

    So it seems that you will hit the mob pretty much all the time.b:thanksb:pleasedb:thanks
