Yesterday, someone pointed out to me that I lacked the achievement for getting killed by Brax, so in my current game I looked at the meager skills that I had and tried something that I'd never tried before. I used the "Skepticism" skill on Brax. Not only does it not turn Brax hostile, but it creates random items where Brax is standing. I could stand there all day waiting for the cooldown and reusing it. That's all it seems to do is create random items at no risk.
I've had it too, but didn't know if I should post this. Someone already talked about this in the 1.1.3 bete feedback thread if I'm not mistaken. I haven't had any problems with it while abusing it to get wands. I'm not sure if it's a bug tho.
