What kills a vampire?

Question

I'm looking to find a definite list of distinct conditions that can result in Final Death for a vampire. I have managed to get a list of most obvious ways, but some of them seem to be house rules and not reflected in the rulebook.

Note, that I'm looking for ways to die, not ways to kill, so "rake him with Gangrel Beast Claws" and "push him into fire" is for me the same answer - death by aggravated damage.

Below I'd like to put a community wiki answer, in which I will start with a list that I have completed in the first place. If you remove anything from it, please state a reason for removal for posterity.

Answer 1

1. Taking aggravated damage while in torpor.

If your character is reduced to Incapacitated via lethal damage, and she takes a further level of aggravated damage, she meets Final Death

2. Losing last level of health to aggravated damage.

Worst of all, a vampire who loses his last health level due to aggravated damage meets Final Death

That would actually include seemingly differing reasons, such as exposure to sunlight, fire or being diablerised.

3. Massive physical trauma (tremendous lethal damage)

An incapacitated or torpid vampire may also be sent to Final Death through massive amounts of bashing or lethal trauma (decapitated, trapped under a 10-ton rock, fed into a wood chipper, caught at ground zero of an explosion, crushed by deep-sea pressure, etc.)

Most of them kill a vampire even if it isn't incapactitated or torpid.

4. Heart removal

••••• The Heart of Darkness
A Kindred with mastery of Serpentis may pull her heart from her body.

It is implied that a vampire without access to this discipline would have a bad time removing his heart. It would make sense to assume ripping the heart out makes him go torpid, but I remember a Level 3 thaumaturgy ritual (Shaft of Belated Quiescence, page 237) that enchanted a wooden stake so that it splinters and grows into the heart as it is staked. The description claimed that un-staking is possible with multi-hour surgery, but attempting to remove it by force cause Final Death.
