Yes.

I more think about how my character works in terms of mechanics, and Vitality and life force have been used interchangeably for so long I've forgotten the difference between the two. I was thinking that the target of her kisses take some of their "Hit points" and then said hit points are used to close her wounds. If you have a suggestion that most closely matches that, I'll use it when making edits.

Ah, I get it now; so it's indeed life force. In that case we're on the same page. As said, she probably wouldn't be able to suck the life force from a Miseria but there's nothing saying she can't try so that's fine. That should be everything clarified unless I missed something, so she's good to go in the Character Tab.

I usually think of someone's energy when "vitality" is mentioned. So not life force per se but sucking their energy and leaving them lethargic.
