Selective Evasion?

I need to make it so evasion will only effect piercing attacks. Any1 know how to do this?


Im pretty sure you need triggers for this, sry for posting here if you dont

argh! Im not sure there is a way to tell if the attacker has a pieced atack! My best idea is to improvise : when a unit is made with a piercing attack, set its custom value to piercing, or something. Then when the hero is attacked, check the attacker for the custom value. If its there, do the 30% evasion check.

There's probably a much better way...
