Hey, crits aren't always kills. And even if so, technically in fire emblem there is no differentiation between killing someone or knocking them out, mechanically you just always deplete the persons's health and the story decides if you killed anyone or not. For example, in fire emblem rekka no ken there were several boss characters you could fight and they wouldn't necessarily be dead, like Erik in chapter 14, you kick his ass and he lives until fire emblem 6.


But, if you don't think it was a crit, we'll just say that was a really good knockout blow.  Game mechanics don't always got to be 1-to-1.
