They get an EXTRA kill every 30 percent.
That can't be right if I do the math.
Staxed died, that leaves us with 80 percent.
Both the wolves and us can potentially kill a villager each, and we may be left with 40 percent.
This grants the wolves two extra kills from our loss of 60 percent, granting them two extra kills. We'll be at 0 percent!
As we lose more than 90 percent they get an extra kill, we'll be at negative 20 percent.
They gain an extra kill, leaving us at negative 40.
This is in total 6 kills for one night if two people die tonight, leaving all villagers dead, except potentially a villager that has a candle.
If we get a candle to save someone...
We'll be down to 60 percent, the wolves get an additional kill, leaving us at 40 percent, three villagers have been killed.
Of course the math would be different if we kill a werewolf, but if this was true the villagers would lose guaranteed.
To conclude, this cannot be true.
Or I am just too tired and I'd have to go to bed.
