Alright! My inquiries have been answered, and since they were answered in bullet point format, I'mma do the same in response to each part. 

1.) Mmmkay, so compatibility can lead to fun stuff.
2.) Gotcha. Head-shots are nasty business.
3.) And okie dokie. Also I don't care if Unlives is a word or not, as that is a fairly good description for it. 

Anyhow, if you wouldn't mind just noting those in your character sheet, that'd be dandy.
