Damage Return

[hdm]

How can I make that skill Undead > Hero > Spiked Carapace return damage,not ony for melee, but for rangers also ?And how can I make this skill ( or any other that returns damage) to be used as an Item Ability (such as Blade Mail,DotA)?

Maybe a damage detect engine would work. I have never tried it, but maybe you can find it somewhere hear.
