How does the Abyssal Armour interact with the "Wolf kill", "Witch kill", and dying because of other reasons?

The Abyssal Armour grants night immunity to the bearer, in the same way that a role such as a Vampire is night immune. This automatically prevents deaths from normal attacks (e.g. wolfpack kills) once per game attacks (e.g. witch potions) and will prevent roleblocks (e.g. Direwolf) or redirects (e.g. Succubus).

As the bearer is night immune, the armour cannot be destroyed by an attack from another player, although it doesn't stop the item being robbed, or the player being lynched.
