Feedback ability with cold arrows

[XxJizzxX]

I need to trigger a feedback ability that drains 10mp x lvl of ability (which i know how to do) and it needs to be triggered because this unit also has cold arrows. How do i trigger the ammount of mana burned each time the unit hits someone?
TY +rep to helpers =)

What difference does it make if the unit also has Cold Arrows? It doesn't matter, you can still give the unit both Feedback and Cold Arrows and it should work fine. Why wouldn't it?

feedback counts as an orb effect as does cold arrows do they don't both work together. Thats what i need because this unit has both of the abilities.

You need to make a trigger that registers when a unit is damaged. This is a pretty advanced concept when done in a "good" way that won't leak.

Sorry if this is too complicated, but here goes:

You need dynamic triggers. That means triggers that create triggers.
You need a system that registers when any (all) units are damaged.
You need to check the source of that damage.

Then you apply your effect.

Edit: This is the best tutorial I could find on making attack-detection. WARNING: This uses the oldschool H2S() bug. Blizzard patched it and as such this tutorial is basically useless.
