Critical Strike Sound Announce?

Real quick, simple one: Is it possible through regular triggers to detect when a critical strike goes off, for the purpose of playing an announce sound to that effect? I have a hero that has a -very- low chance for a -very- high crit, but I wanted to have an amusing sound play if they manage to do it.

You can go to your Object Editor and adjust "Sound - Effect Sound" under the ability, but that only takes the default sound sets. As for using triggers, the "Unit - Specific Unit Event" Event trigger only takes active skills, and not passive ones. I'm pretty sure there is a way around it involving more advanced methods, but I wouldn't know.

wouldnt it be possible to use "a unit takes damage", and then check if that damage is "alot" higher then the min-max dmg? If so it'd probably be a critical strike. (would probably be rather hard to use with lots of other +dmg abilities/items)

Well, actually, there is no way to properly detect min-max damage. I'm pretty sure the only way to do this is if you trigger your own critical strikes (which isn't that hard).
