Make Evasion reduce damage by 1% for each percentage the hitroll missed the target. This would cap at the user's scaled CEL.
For example, if the target has 220 evade and the to-hit check on the autohit attack rolled 200, you would take 20% less damage. If you had 100 evade and the hitcheck somehow rolled a 50, but you had 10 CEL, you would not have 50% reduced damage, you would have 10%.
If this would be too low or too high for damage reduction, change the initial formula; Evasion could reduce damage by 2% per percentage, or evasion could reduce damage by 1% per two percentage.
