Damage Mitigation Calculator 1.2.xls - 28.0 KB
This is the calc sheet (excel file) i use to plan the equipment for my characters. You can use it to min-max the amount of damage you're "avoiding". You can play with the numbers, check which configuration between AC, Dodge, Incorporeal gives you the best results.
As a general guide line try always to have more than 70% total mitigation for every melee character that want to step into an high level Epic Elite. How to do it, it's up to you: more dodge, more AC or more PRR?
The Calc Sheet comes with two builds already inside. The first one it's a Melee FVS, the second one it's the DDD build i'm using on my tank. Feel free to modify the numbers, copy & paste the formulas.
This very simple work is based on this formula, though i considered the complement to 1 of the same in order to get the mitigation percentage, and not the damage you're taking. The component that calculates the percentage to get hit based on AC and the monster attack bonus has a minimum in 0.95 not in 1: as far as i know you always mitigate 5% damage despite how low your AC is.
