Workshop

Hos, does it bother you that the upgrade only works once per game???

Lolda? Well, then, even more so! Turning the city into a paranoid herd that produces building materials in cosmic quantities and can't decide whether to use its own ability or wait for the EXHIBIT! Is this Mafia? It looks more like a bore, really.

The Mafia has the advantage that while one is killing, the others are leveling up.

But the upgrades are unique and work like an ability, so there's not much point, really.

And in general, Aragorn correctly pointed out that they are all warriors.

I AM A WARRIOR! I HIDE UNDER A CLOAK, CONCEALING MYSELF FROM THE ENEMY! I CONSTANTLY THINK ABOUT WHEN THEY WILL COME TO KILL ME, SO I CAN USE MY ABILITY, BECAUSE THE CITY WAS LEVELING UP ALL THE FIRST NIGHT! I THINK, I SEND THE ABILITY, I GET KILLED, HOW AM I A WARRIOR, DAMN IT, A BATTLE-HARDENED WARRIOR.
Well, in general - how it will be.

Hos, remove the upgrades and you'll see that, in theory, only Aragorn has a permanent passive ability, and there's just a city that shoots, Legolas. There's also an ambush with Faramir, but it's not just about protecting the target, but also blocking it!
With Éomer, the cavalry kills the attacker, the target doesn't save. Everything is fine.

Ah, yes. But there are also 3 maniacs, a journey to the mountain, a search, well, it's funny. One Uruk-hai will be killing, getting off on the chance of being unidentifiable.

And finally: are you trying to play my terrible game?

No. I just like the original Lord of the Rings universe + I want to help those who will play your terrible game get at least some fun.

And here it's like a computer game or real life in reality?

It would be better to write a book.

and also strengthen the Mafia by completely removing evidence against Lurtz.

In general, the ability with the absence of evidence is overpowered. Because it turns into a game of abilities/psychology, depriving the Hive Mafia of its main feature. And 100% unidentifiability is a powerful thing.
