I read on page 223 about vampires entering torpor due to aggravated damage that the vampire will burn all the remainder of the blood they have to try and fix the damage. Once depleted they enter torpor as above.

That would mean they remain in torpor as long as their remaining Humanity dictates unless they are fed blood from a vampire with higher blood potency.

My situation is this: Players have a torpid vampire on their hands who has full aggravated damage track and no blood left. They want to wake the vampire from torpor and they have access to higher generation blood to do so.

What are they facing under these circumstances?

• Do they need to feed the vampire in torpor a lot of some source of regular blood over successive nights to allow them to mend their aggravated damage first and then the high potency blood to wake them earlier than their Humanity dictates?
• or, does failing to repair themselves place them in a standard torpor state that they can be awakened from immediately because the end of the second bullet point indicates that failure to mend they are in torpor "as above". Would that would mean, somehow, all their aggravated damage disappears?

The rules on this don't seem to be clear. I lean toward the first bullet on this but am interested in other opinions in ruling on it.
