EDIT 2.0: HAHA that's what i get for not testing the link line a newb. It should work now and will take you to a download page.
Always hear people having big lengthy discussions about evasion vs armor and pros and cons of each. I, being the type who loves numbers decided to make a spreadsheet that will crunch any numbers you toss at it for you.
It properly accounts for min / max dodge chance on crits and non crits, max armor damage reduction and elemental damages on hit with resistances. Any number of hits.
I know this doesn't tell you about HOW it works, and i cant use it to prove evasion isn't random, but the mechanics thread does that better than i could.
For a very approximate guess at the stats of white enemies your level, punch in your stats, raise Total Attacks to 10,000 or so and fiddle with their stats until the numbers line up with your character sheet.
Anyways, without further rambling, here ya go!
If you don't have excel you can use Google Spreadsheets (no download) or Gnumeric.
To open it in Google Spreadsheet click file, import and find the saved file.
If you see anything that is wrong or any features you would like to add, tell me and I'll see what i can do :D
