How do Shadow Shifter and Avoid stat stack with each other?

>.>

4 types of avoid.
Avoid. Which is the stat in your window. This calculates an Evasion Rate.
Avoid Rate. Which multiplies your avoid by whatever percentage it is, this contributes to the Evasion Rate.
Dodge Rate. This is a flat chance to avoid an attack.
Evasion Rate%. This multiplies your evasion rate by whatever percentage it provides.

Evasion Rate is the rate of a monster missing you. Suppose you had 6500 avoid and 10% er%. 6500 avoid calculated itself to say, 62% evasion rate for Horntail. Take the 62% multiply it by 1.1 and you get 68.2% evasion rate. Now suppose you had Shadow Shifter, which is 45% dodge rate. Take 100% - 68.2% = 31.8% and multiply that by .45 which is 14.31% chance that it will proc.

So Shifter's proc rate is calculated on the remaining hit chance... alright, thanks.
