(sorry to add this so soon)
How does Blood Rage interact with damage that can't slay a unit? Does "can't slay a unit" functionally mean "if this damage would reduce the unit's HP to zero, instead reduce it to 1", or something else?
Lemme rephrase: since Blood Rage triggers on going to zero, and the unit is specifically not slain, can abilities like Plague reduce a unit with Blood Rage from 1HP to 0HP? My intuition is that they cannot, but if you were to ask me why I couldn't give you a great answer.
(but yeah these abilities obviously can't slay a unit that has reached zero hp, activated Blood Rage, and is now at zero hp but not slain yet, and apologize for not making my question clearer)
