For the destroy minions quest, which minion deaths count towards my quest progress? For example, what about these cases?

* If I cast a spell that destroys an enemy minion.
* If I cast a spell that destroys my own minion (like Sacrificial Pact, or maybe even Power Overwhelming).
* If my minion attacks another minion and the other minion dies.
* If my minion attacks another minion and my minion dies.
* If another minion attacks my minion and the other minion dies.
* If another minion attacks my minion and my minon dies.
