Detect Killer

[0.to.the.9]

Hello!

I'm trying to create a spell, something like absorbing souls.
And I got 1 short question.

Event: unit dies
Condition: if 'killer' has an 'ability'
Action: add 'N' health to killer

The problem is in killer detection.
'Damage source' wouldn't work, right?

How can I detect killer using GUI or CustomScript?

Also, there are little notes in gray when selecting function which describes what it does and when you can refer to it.
