Nairu was isolated, Wolfset was probably blocked. (Or not?). And who blocked him? "According to the description of the block, it looks like it's the ultimate ability of one of the Barbarians - an incomprehensible language." She must have used her ultimate ability, right?
Toria was drugging the bar-bot. In each of the three nights, there is someone who is drunk; the only thing left is healing.
In my opinion, the killed Vesper was a cheater. Since the maniac killed him, there should be some evidence. By the way, I found a suitable clue on Toria.
Again, a table is needed. Something should be clear on it. ;)
