Oh look, that big belly I promised. What with me plugging in Nikola into settings like Fable, it's obviously she's going to end up in her usual shenanigans. Generally you're supposed to have to use silver weapons and stuff to kill balverines effectively, but stomach acids should do the trick pretty handily too, right?

Also, I guess technically you could say there are technicalities about this since it's a balverine and they're kinda beasts, but they weave back and forth into werewolf territory and sometimes it's a disease and sometimes it's not? Idk, Nikola's got a tough gut though, so she'll probably be fine.
