Mafia 11. X-men

The Zubr was killed, not healed, but, miraculously, he's alive! It must be that 50% of the damage was negated.

Or maybe the Sabretooth only has 50% defense?;)

Wolverine is the protector of Arandor (some kind of animal - definitely not a Beast, not a Cat, but compared to the 3rd night - it's Wolverine).

The Sabretooth could be an animal, that's one thing. And secondly, if the defense didn't work, then there might not be any mention of it. See the rules.

"THEY" - the poison from the Apocalypse maniac didn't work, and a person from the same group came to finish the job - the maniac, Zlyden.

Maniacs are loners, that's one. The victim (i.e., me) says "they" himself. That is, they were there at that moment. Considering that the apocalypse probably didn't come to me twice, "they" are the Mafia.

I still can't see the clue about the murderer of Cash.

That's because there's no clue pointing to me.
That's why no one is particularly eager to mention the first night so that they can quietly hang me...
