Poison damage calculator.xls I've recently finished work on a poison damage calculator for Diablo II. After a few revisions, I'm now reasonably confident that it's accurate (or at least, I've corrected all the errors that I've been able to identify myself). It covers poison damage from both skills and items (and combinations thereof) with +% to Poison Skill Damage, -% to Enemy Poison Resistance, Lower Resist and the target's Poison Resist % and Poison Length Reduced by %. Unfortunately it doesn't really cover duelling, but it can still be used to help calculate poison damage to your opponents. It's a Microsoft Excel worksheet. I've protected all the cells that don't need any input, and those that do require input are light grey or green. I've made some attempt to make it idiot-proof, but my expertise is limited (e.g. no list or check boxes) and it still operates mostly on the 'garbage in, garbage out' principle. It should (hopefully) be pretty self-explanatory and doesn't require in-depth knowledge (if you know that you can't equip two helms or socket a dagger with 6 perfect Emeralds, you shouldn't have any problems). If you do have any problems, let me know and I'll see what I can do. Here are some links which go into more detail about how poison works: Calculating Poison Damage Poison Skills Information Rabies Mechanics UPDATE 24 MARCH 2010 I've updated the calculator to take account of Poison Nova's increased damage in 1.13. UPDATE 30 SEPTEMBER 2012 I've updated the calculator to correct poison length calculation for Multiple Shot, Strafe, Blade Sentinel, Blade Fury and Blade Shield. However, I experienced an error when attempting to upload the new version and unfortunately I had already deleted the old version. The updated calculator can be downloaded by clicking on the following link: Poison damage calculator.xls Those who do not have Microsoft Office can still access this spreadsheet by downloading OpenOffice for free. UPDATE 24 NOVEMBER 2012 I've updated the calculator to add poison damage and length from charms and jewels, following an error report from Zyr of the Amazon Basin forums.
