Alright.... I'll post this here since I feel like I need to ask. I'll spoil it, so if you don't want any potential spoilers concerning a 'Spiral Stone', don't read that.
Alright, as I was scoping out a mansion on the outskirts of town, far enough away from regular zombie spawns, I noticed an odd room. It had 3 counters on it; one had nothing on them, but the others had assorted weapons, including a katana(Squee!), and a few items I haven't seen before. One was, boringly, a candlestick, and the other was a Spiral Stone. I broke into the room, looted the Katana and a few gold rings and silver necklaces, and decided that I might as well take the Spiral Stone for kicks. It was getting late, so I went to a non open to the outside room and drank some vodka, where I noticed the first odd thing.
A message showed up, basically, 'Oh god, what's happening?' I was rather confused, then shrugged, taking another drink and started to read a book. That was when everything went nuts. There was odd graphical glitches, and the symptoms of schizophrenia, your mother and ant and zombie hallucinations, when I decided to take inventory. The only thing that seemed odd was, well, the Spiral Stone, so I chucked it and took a few steps away from it. Nothing changed, so I sat in a corner, tormented by images of my mother and zombies until it got dark and my character went to sleep. Afterwards, I woke up, and the symptoms were gone. I ran away from the mansion immediately.
At least I got a katana out of it. I'm using Darkling Wolf's mod; can anyone confirm that the Spiral Stone caused all that? And if it did, what the hell is it? Or, if that's too spoilery, should I go back and pick it up?
